I know you're half joking because this seems like a tired subject, but it's something that, at least in this very specific niche of short barrels, for short range, when using a suppressor but still supersonic ammo, I have a lot of questions about. I think if you really really want to optimize that you might go with something like 6.8 SPC in a 9 inch barrel, but if we're keeping with regular 5.56 brass and magazines, I'm torn between which caliber to keep next to my bed.
@@tuongtran4862 I mark all my converted 223-5.56 magazines with a big colorful stripe around them, and with the words 300 AAC in big black letters. They will never see a NATO round or anything else in that caliber.
You forgot that it may cause excessive ammunition expense or excessive time lost reloading. You’re going to definitely have one or the other. $1.25/rd for 110gr vmax or $0.35/rd to load the same ammunition. Those are not the cheapest ones that you can find for that load, but it’s what I have seen the last time I looked. I don’t shoot much supersonic.300 blackout. It’s mostly just for self defense and varmints.
Working on a PSA Phoney Badger build. 8.5” 300 AAC collapses down to 24” and is the best truck/backpack/brush gun around. 5 years on and this video is still the best on YT.

@user-pe3mp6nx5e Update to my platform. I saved up and was able to get a Sig Rattler in. 300 BLK. Same uses as stated in my OP, but in a much nicer and smaller package.
You put an enormous amount of time to make this video, especially looking at you board with all the ballistics. You have done the best research that I've seen yet!
I have a 16" BLK and I use it to hunt. I load my own ammo, like he says 110gr to 125gr. Drops deer to 200 yards and super cheap to load. I love this round
@@Bmxr1991 I believe the full burn is only for subsonic powders. You would gain at least 200 fps out of a supersonic round going from a 9 to 16 inch barrel.
I reload 300blk subs for 12 cents per shot. I load a powder coated cast bullet that will shoot moa @ 100 yards. If you buy a blackout buy a reloader, it will pay for itself.
The fact that this never became a top comment astounds me. I still can't believe people complaining about the price of blackout but refuse to handload.
@@nnerrfman6326 If you are talking about blackout, I use H110 for supers, and CFEBLK for subs. For the primers I use either the chlorate based if I'm going to shoot a lot (because hey are corrosive and you have to clean it out with water) or the non-corrosive yellow stuff (I forgot the name of it, but it is in the primer handbook from the 1950s)
I need to get back on this. 8 years ago i was starting to work up a load with cast powder coated bullets but then the powder shortage happened and I just decided to put a pause on reloading and hoard all my powder and lead. Still have about 6# of IMR4227. Need to actually find a good 200+gr hollow point boat tail mold and get back on this.
My blackout with a 10.5" barrel is probably my favorite rifle. Fun to shoot, easy to pack and operate, and seems to be a heavy hitter. Not to mention the vast bullet weight options and the subsonic abilities.
@@ryancoker6834 I wouldn't know, not a hunter, but I've heard good things. Mine is a cheap Grid Defense upper, 1:8 twist with M-lok in FDE, pistol length DI gas. Lower is a PSA with a SBA3 brace. Have a Trig MRO and a set of HK style Troy flip ups on top. Internally it's got a Titanium-Nitrite BCG from Brownells and a placeholder charging handle (not really a fan of either, but they work, so...). What is yours, if I may ask? 🙂
YorktownUSA looking back, I should have gone the less expensive rout. I got way too excited when it came out and got an AAC rifle costing a few thousand. Now, although I love it, that’s $ I could have used elsewhere.
Nicely Done. Would like to add, one of the main factors in making 300Blk so effective with shorter barrels and less gassy than 5.56 and x39 is due to the limited case capacity all 300 Blk loadings are using a much faster burning powder. Some of the best loads use magnum type pistol powders and you are achieving 100% burn in 10 inches or less. PLEASE do not confuse 100% burn with optimal barrel length as the gasses are still expanding and providing increased velocity.
You mean like 30 caliber loaders have been doing for decades? 308 is the most re loaded center fire cartridge there is. There are many recipes to make a 300 blackOut and you just shoot out of an AR10, the cartridge just looks different. The advantage is when you want to shoot the more powerful 308, you can. The fact that this is being explained means you don't load your own ammo, or you're really really new to it.
For hunting I like to use 125 grain out of a 9" barrel suppressed with a 3x prism scope. Where I hunt there is to much thicket and you'll never shoot further then 50-60yrds. It just drops white tale. Awesome round. Great presentation.
Cleetis McDougall second that; if you could, add 16 inch barrels. Guessing reliability will go to the AK and Suppression will go to the 300 blackout. Love my MCX - the Gemtech One suppressor makes it a joy to shoot. Took two trips to SIG factory for warranty work before it became 100% reliable (kind of shitty). Using subsonic RUAG ammo keeps you under supersonic. Sold my AK and possibly looking to get one again; so a video on the topic would be great.
Brother I had to revisit this one because my next project is going to be a 7.5" 300 Blk: Bag/CQB gun...I wish I could've served along side you when I was in the Army, you are crazy with the gun talk brother...🐐
I have 3 college degrees in two fields (none of them "arts" degrees); I can confidently say that I gleaned more from this than any course that contributed to that. It's rare that I can sit through an entire video and not find myself annoyed, this guy gets it and breaks it down succinctly.
I have lost count of the number of times I've watched or listened to this video, it is so informative. And every time I've done so, I get something out of it that I either missed or that didn't soak in the times before.
Very well done. I interpreted the 9” barrel rule as the minimum length you need to have the benefits of all the different types of ammo you can get for 300 blk out. Definitely interesting perspective
My understanding was that 9" was all that was needed to get complete powder burn. That doesn't mean you won't gain velocity with longer barrel lengths, you still have tremendous preasure in the barrel. I think many have confused this with being the best length. The length should be determined by what you are going to do with it. IMHO
Been watching your channel for for a few years now. Your reviews are generally in my range of budget, comprehension, and area of interest. This video is full of awesome insight on 300blk. Just finished my build and your video definitely had a hand in it. Thanks for your hard work!
@@Mrgunsngear is this the right home defense load for the AR-15? Or would something more like the .458? I know cost plays a part because practice, practice, and more practice helps the odds for a better outcome. But the slow speed and mass of the .458 reminds me of a 12 gauge slug
@@bret9741 the .458 socom like a 12ga would be a poor choice for home defense. They have way too much penetration and will go thru multiple walls. You want a round that will create a large wound cavity and a reduced chance of penetrating walls. One of the best options would be a .223/5.56 with a hollow point bullet in the 45-60 grain weight. They tend to break up in walls while still being effective.
@@bret9741 try ammobuy.com it let's you search by caliber. They show a website that has Black Hills 50 grain TSX 50 round box for $100 in stock.

God for bid we actually say it or youtube will delete this comment.
Loved the video. Lots of details and data, as well as, relative comparison between the 5.56 and 7.62x39 rounds. Reminds me of a Paul Harrell Video when he tells you this is the boring part, and that’s the part we love the most. Outstanding information for anyone looking to make a next firearms purchase. Every time I watch your videos I learn something new.
To be fair the effect of decreased barrel length on 300 BO is less than 5.56. That said, longer barrel pretty much always means more velocity no matter the round.
3rd time watching this. I'm very interested in building a 300blk pistol for my home defense gun. This video is extremely helpful with barrel selection, ammo selection and general info. Really, this is one of your best video's yet.
Did you ever build it? If so, what size barrel did you end up choosing? I'm trying to put on together now. I've got everything except the upper. I can't decide if I want a 7.5, 8.5 or 10.5.... I'd like a smaller options for shoving in backpack or car. But I don't want to sacrifice ballistics.. although according to this vid, there isnt a huge diff between 7.5 and 10.5...
Finally someone who tells it like it is. I got more answers to my questions in this 27 minute video than 27 hours of watching TH-cam videos on the subject. I am a 300 BO fan and have 2 uppers for my one lower. I am also a subscriber now. thx for the info. I reload all of my 300 BO cartridges so I get a bit more range time than the normal shooter. My "go to" cartridge uses the 115 gr. Lehigh Controlled Chaos bullet for "varmint" control. I also practice with 155 gr bullets. I have a 1:8 twist barrel that I fire lapped with David Tubbs components. I was able to get sub MOA groups with the 115 gr Lehigh bullets in the AR platform. I have been watching and implementing some of the recommendations of Grand Thumb in set up. Your video is the icing on the cake!!!!
Great video Mike. I took a hog in Missouri with my 16” barrel .300 BO rifle with a pistol length gas system using 125 gr. Hornady American Gunner ammo. One shot at 80 yards. Hog down and done instantly.
I consider you one of the most informed and best in youtube when it comes to information on firearms and everything related to them. Thank you Sir for what you do.
The thing behind 8.5 or 9 is that the round achieves full burn at those barrel lengths but it will still benefit from a longer barrel since the gasses behind the round are still expanding even up to 16 inches
@@ssspencerjr I've shot it outdoors without ears on and it's doable. Indoors I'm sure it would hurt, but if I had to pop off 10 rounds I don't think it would cause permanent damage which is why I went with this set-up.
@Nick 718 Yes, I found out the hard way it doesn't stabilize Hornady 190gr Sub X rounds. Tore up my can and had to send it Dead Air for repairs which they were great about.

@Nick 718 Yeah I was pissed to say the least! Now I make sure to test out new ammo without the can on first 😂 live and learn! I'm planning on making a video about the experience and will test out the new subs on it as well
One reason you may want a 16 inch 300 blackout is legal issues. In Florida you can have long guns loaded and openly displayed in your vehicle but pistols must either be on your person or locked in a container. If you want a truck gun in 300 blackout it would have to be locked in a container if the barrel is less than 16 inches. Also, with the pistol brace rule from the ATF all of your 300 Blackout pistols are now illegal or you have to ditch your brace or have to be registered with the ATF.
I have a Wilson Combat 18" Barreled upper its accurate and I've taken a few hogs with it. I have found that once you get up past 150 Gr bullet weight the projectile drops significantly and you need at least a 30mm scope if your shooting at longer ranges or you'll run out of elevation adjustments. I like to stay around 110 to 125 gr bullet weight that seems to be the most optimum bullet weight for hunting.
I as well - I have settled on the 115gr Lehigh Defense (Controlled Chaos) = Fragmented Bullet - so there is mostly never a big issue of over pentation and going through walls & hitting a family member. I have 6 pre-Loaded 30rd mags for Home SD - each mag contains 20-CC rounds & 8 -194gr Maximum Expansion rounds - placed through out each magazine. Hunting mainly Wild Feral Pigs & other annoying Predators - I choose the 110gr & 120gr TAC-TX. My range is only out to 200yds with my Holosun HS510C - This is Perfect for my needs! -- I don't pretend to be a wanna be sniper - the 300BLK & 200yrd range is ideal for my physical capabilities. Lastly for the Moment SHTF - My son & I have more then we can carry (30round mags) - loaded with a variety of 110gr to 147gr. (What ever we could find over the past 15yrs. We both shoot via 16" barrel - Mine has a 1-7.5 twist.
U always give us fantastic content and your "grunt work" is obviously extensive thank U for doing it so we dont have to. Thanks for the term grunt work 406 mountain man.
Thanks for answering my question! I’m glad to see that I was on the right track on something I have little experience with. Obviously, there is a ton of information I will need to continue to research.
Talk about a guy who really knows his stuff... excellent video. I own a BCM 9” 300 BLK I use Gorilla’s 110 grain Varmageddon and Hornady’s Black 110 V-Max for self defense, home defense and most other situation along those lines. Subsonic end, Gorillas Silverback 205 grain and Hornady 190 grain Sub-X. Practice ammo is Sellier & Bellot 124 grain FMJ and 200 grain FMJ. Using an AAC 762-SDN-6 suppressor I can say I’ve ever had an issue running any of the ammo mentioned above. Also just in case from my experience mentioned above, the BCM 9” that I own came from Bravo as a 1:7 twist and buffer which I believe is an H1 buffer weight for anyone concerned about not stabilizing and or feeding issues. No issues at all suppressed or unsuppressed. Thank you so much for all your videos and work that you put. We greatly appreciate you my dude!
The recce? I have a BCM recce 9. I totally agree with your comment. I watched some videos today going over buffer weights. They seemed to think if you shoot suppressed the buffer should be an H2 at least. But I haven't had any problems with the H1. I thought about putting in an H2 because they say it'll help some recoil (not that it's an issue) but nothing to do with the cycling using a suppressor. The only issue I've had at all with the gun is because I bought 1k rounds from a guy who loads. Somehow on a few of them after the primer is fired it comes out of the round then gets stuck between the bcg and the lower jamming it up. Other than those shitty rounds it's pretty solid
Ive come back and watched this video 3 times now. One of the best videos you’ve made @mrgunsngear . I wish youd make a part two of this video where you’re comparing the accuracy and range capabilities of the 300bo cartridge offerings out on the range.
Jason J. Ayala P. LMFAO Brother, we can’t even buy gen 4 or gen 5 Glocks because “They’re not on the roster” of approved pistols. It’s literally why Glock is still manufacturing new gen 3s
I'm absolutely new to 300BLK, I have learned many many things in this video and appreciate it very much. In my country a semi-auto in 300BLK is easily available but 5.56x45/7.62x39 is harshly regulated (like a class 3 in the U.S.A) and the minimum length for the barrel must be 18", finding informations for long barrels in 300BLK online was complicated and depressing, this, again, was really useful thank you a lot Mrgunsgear, watching another of your video also compelled me to buy a "lock" for my Beretta 1301 bolt release to avoid the dreaded turbo-jam. Regards.
Thanks, from all of us 300 fans. The Gorilla ammo is great, and I've invested in the copper rounds too. 16 inch barrel, supersonic. Works great. Mine is strictly for defense. I appreciate all the research you did on this.
Built. Finally. Took me 2 months, first build from scratch. Can’t tell you how much this channel has helped me learn. Now time to play super super while I wait for the government.
Funny how these things just turn into either or conversations. Just get one of each! I will say though, my 8.5" SBR in 300BLK with subsonic & can is obscenely fun.
Federal HST+p 230 grain rounds hurt your hand while shooting with a handgun. I know 300 BO has better terminal performance, plenty of videos discussing that. But I would definitely consider a .45 pcc with +p rounds for self defense.
Expected a comment section full of blackout hate, surprised to see the opposite. Great video. Blackout is a great round and the prices are starting to get reasonable.
Hi. I love so much your very informative and educational videos. Could you make the same detailed video for barrel length velocity/energy for 223/556 as they are also so popular these days?
Man what a thorough presentation. Excellent job. Yeah everything is a tradeoff, but I think the handiness/maneuverability with a suppressor is worth the slight loss in velocity. A case for 8-10" barrels
I had a friend ask me about the gas mileage with my Dodge Hemi pickup I told him if I was worried about gas mileage I would have bought a Neon same applies here. I shoot enough to be proficient but not enough to worry about cost, besides I reload so I can shoot a lot on the cheap. I know some don't have the time or confidence to reload but it ain't rocket science and a lot of fun.
I bought an AR earlier this year (300 BLK with a 16' barrel). People in an AR group I was in on FB were talking trash about the barrel length. From what I understand about this caliber and why people buy shorter barrels is because they generally use a can. I have no intention to buy a suppressor. I cared about having something that packs a helluva punch up close and can still pack that punch at some distance. I also caught a really good deal on the gun.
Next, compare it to 6.8 SPC and 7.62x39; the 300 Blackout will show it's true colors. Good for short barrels and good for suppressor use, but when you start using longer barrels, there are better cartridges.
@Nick 718 While 300 Blackout wasn't intended for longer barrels, it, like all other calibers, do benefit from longer barrels. 6.8 SPC was also designed for CQB, and it achieves that and then some; the ballistics are better than 5.56, 300 Blackout, and 7.62x39. And while we're talking about it, no, 300 Blackout does not out perform 7.62x39; when comparing similar grains, 7.62x39 has more energy than 300 Blackout or 5.56 62 gr green tip at 300 yards.
Nick rockz a 5.56 is flatter shooting and cheaper. But, I rarely shoot beyond 200 yards because I don’t see game at longer distances here in the Texas brush country. Within these distances the.300 is measurably more effective on game.
To Start right off, I don't do a lot of Human hunting anymore....(former XVIII Abn Spcl Warfare SkyDragon here, waaaay back (VN))so when I built my *first AR* style (back in the 'old' days, AR's weren't worth shit in the bush-but they got better) I went for the 300BLK, but also built it with a 20" barrel (kind of amazing what a decent reloader can achieve with this set up). I can make single round reliable game kills up to around 250 yards or so under 'field' conditions (no bench rests lol.) With a good rest of some kind, bout a 100 to 200 more depending on other std enviro concerns...wind, temp, altitude, lighting etc. With a good bench, and the time to dial in a good scope, I can punch paper out a fir distance more than that.
This vid was very helpful for deciding the final specs for my build. I finally finished it, tested it at the range - and it worked! Thank you so much for getting into the specifics!
I've been researching my next gun/parts quite frequently and this covers so much of what I've been curious about. Thank you for this great information, sir.
I have 8 deer in the freezer which are proof of the effectiveness of the 125gr Nosler BT out of a 16” barrel (2200fps). Also, 300BLK supersonic suppressed is MUCH quieter than 5.56 suppressed.
Picked up my 300 BLK pistol from my FFL today. Thank you for the info needed to go down this road. I have some 110gr Noveske with the Nosler Varmageddon bullet to start and the 150gr Fiocchi for the range. I'll now spend a lifetime testing 300 BLK rounds for fun.
Adam Huffman 300 yards is really about the limit of any intermediate rifle caliber like 5.56, .300 blk, or 7.62x39 anyway. Honestly, I prefer to cap them all as 200 yard cartridges for an ethical behind the front shoulder kill on a small to medium size adult whitetail deer. Considering the wooded areas I hunt, that’s usually plenty of range. At 300 yards and beyond, I’d rather step up to a true rifle caliber like .308, .30-06, .270, etc. Now, it’s certainly true that deer can be put down with lesser calibers like .17HMR, .22WMR, or even .22LR. You’re talking about critical shot placement into the brain in order to keep a deer from running forever before dieing at that point though. I’m not talking about what can be done especially if it’s taking game for survival. I’m talking about making a clean ethical kill in a non-critical hunting environment.
Im using a 300blk for deer season this year. I also chose winchester 150gr deer season xp. I'm use to a 30-06 with 180gr corelokt so I'm just wondering how those deer rounds worked with your 300blk?
Funny how this was made in March of 2019--which is 5 years before I'm writing this very comment--and I'm watching this literally 2 minutes after ordering a 7.5" .300 Blackout barrel with a 1:5 twist. Thankfully it looks like I made the right decision! Yes, I know you can get better terminal ballistics with longer barrels, but it just seems like the best velocity & energy per barrel length ratio. Man, .300 Blackout is such a great cartridge if for no other reason than how it does *great* with shorter barrels!
I don’t mean to take away from what this video is about. What watch is that you have on? I’m an avid watch collector/lover. Thanks in advance, and this has to be the absolute best and most informative video on 300 blk on TH-cam. Great job!
I keep a suppressed 8" 300BLK with subsonic rounds ready for home defense. And I keep a 16" unsuppressed upper for hunting with supersonic rounds for hunting. And a .22lr dedicated upper for plinking. Got rid of the .556/.223 uppers to mitigate the 300BLK rounds accidentally being loaded into a .556/.223 upper. Only need one braced lower for all of them. Takes up less space in the cabinet, lol
@@---tx9xx subsonic 147gr 9mm is 326 foot pounds Subsonic 220gr 300blk is 520 foot pounds Not to mention the length and weight of the 300 bullet is better. And it’s much more reliable than a pcc
Excellent info Mike! Very informative.. I’ve been eyeballing the SR-30 in 11.5” to compliment my incoming SR-25 so I’ve got something to share that can with, trying to get as much info before throwing some cash towards the project. This video came in at the perfect time 👊🏼

@@YorktownUSA it's a pig killin machine too.. I find myself shooting it more than any rifle I own
@@ryancoker6834 I wouldn't know, not a hunter, but I've heard good things.
Mine is a cheap Grid Defense upper, 1:8 twist with M-lok in FDE, pistol length DI gas. Lower is a PSA with a SBA3 brace. Have a Trig MRO and a set of HK style Troy flip ups on top. Internally it's got a Titanium-Nitrite BCG from Brownells and a placeholder charging handle (not really a fan of either, but they work, so...).
What is yours, if I may ask? 🙂
YorktownUSA looking back, I should have gone the less expensive rout. I got way too excited when it came out and got an AAC rifle costing a few thousand. Now, although I love it, that’s $ I could have used elsewhere.
@@scott2228 At least you can brag. I plan to purchase something sweet in 5.56 in the next year or so. Expensive yes, but worth it :)
Nicely Done. Would like to add, one of the main factors in making 300Blk so effective with shorter barrels and less gassy than 5.56 and x39 is due to the limited case capacity all 300 Blk loadings are using a much faster burning powder. Some of the best loads use magnum type pistol powders and you are achieving 100% burn in 10 inches or less. PLEASE do not confuse 100% burn with optimal barrel length as the gasses are still expanding and providing increased velocity.
Thank you for understanding basic physics.
300 blk is a re loaders caliber if there ever was one . It is also a fun caliber to reload since you have so many options .
It is a very versatile cartridge to reload.
You mean like 30 caliber loaders have been doing for decades? 308 is the most re loaded center fire cartridge there is. There are many recipes to make a 300 blackOut and you just shoot out of an AR10, the cartridge just looks different. The advantage is when you want to shoot the more powerful 308, you can. The fact that this is being explained means you don't load your own ammo, or you're really really new to it.
@@kalidileriousor he prefers the more widely available ar15 quality parts
For hunting I like to use 125 grain out of a 9" barrel suppressed with a 3x prism scope. Where I hunt there is to much thicket and you'll never shoot further then 50-60yrds. It just drops white tale. Awesome round. Great presentation.
Cqb’in deer, nice🤘🏽
Do a 300 blackout vs 7.62x39 video, suppressed and unsuppressed. Both with like 10.5in barrels. Subsonic and Regular ammo.
Cleetis McDougall second that; if you could, add 16 inch barrels. Guessing reliability will go to the AK and Suppression will go to the 300 blackout.
Love my MCX - the Gemtech One suppressor makes it a joy to shoot. Took two trips to SIG factory for warranty work before it became 100% reliable (kind of shitty). Using subsonic RUAG ammo keeps you under supersonic.
Sold my AK and possibly looking to get one again; so a video on the topic would be great.
@@fnhcat6714 I was talking about AR uppers.
7.62x39 is like 300bo, barrel length doesn't affect velocity very much at all.
@@TCarstens1 certainly not past 12" anyways, there's chrono out there of draco vs akm vs rpk and they're all around the same velocity

Brother I had to revisit this one because my next project is going to be a 7.5" 300 Blk: Bag/CQB gun...I wish I could've served along side you when I was in the Army, you are crazy with the gun talk brother...🐐
How many course credits do we get for watching this video?
I will give you a doctorate. I gave myself one 🤣
I have 3 college degrees in two fields (none of them "arts" degrees); I can confidently say that I gleaned more from this than any course that contributed to that.
It's rare that I can sit through an entire video and not find myself annoyed, this guy gets it and breaks it down succinctly.
🤣
All of the credits
Lifetime
I have lost count of the number of times I've watched or listened to this video, it is so informative. And every time I've done so, I get something out of it that I either missed or that didn't soak in the times before.
Very well done.
I interpreted the 9” barrel rule as the minimum length you need to have the benefits of all the different types of ammo you can get for 300 blk out.
Definitely interesting perspective
Not really a perspective more of a fact.
My understanding was that 9" was all that was needed to get complete powder burn. That doesn't mean you won't gain velocity with longer barrel lengths, you still have tremendous preasure in the barrel. I think many have confused this with being the best length. The length should be determined by what you are going to do with it. IMHO
10.5 is. From all my research lately
I really appreciate the time you took to explain all this stuff.
Can’t remember if this is the 4th or 5th time I’ve watched this video! Best 300 blackout video out there!! Thank you
This video educated me and debunked the myths I had come to believe. Thank you again for your hard work brother
KNOWLEDGE, DATA, DETAIL, AND EXPLANATIONS ARE GREAT. AND NO OPIONS BASED ON "JUST BECAUSE". A GREAT HELP.
How have I not come across your videos is beyond me, you mentioned onther channels I watch daily. Appreciate you man.
Been watching your channel for for a few years now. Your reviews are generally in my range of budget, comprehension, and area of interest. This video is full of awesome insight on 300blk. Just finished my build and your video definitely had a hand in it. Thanks for your hard work!
Humble, educated AR expert. Really
This was really informative. I'm looking for a 300 blackout for home defense, and this really helped.
Subscribed!
welcome!
@@Mrgunsngear is this the right home defense load for the AR-15? Or would something more like the .458? I know cost plays a part because practice, practice, and more practice helps the odds for a better outcome. But the slow speed and mass of the .458 reminds me of a 12 gauge slug
@@bret9741 the .458 socom like a 12ga would be a poor choice for home defense. They have way too much penetration and will go thru multiple walls. You want a round that will create a large wound cavity and a reduced chance of penetrating walls. One of the best options would be a .223/5.56 with a hollow point bullet in the 45-60 grain weight. They tend to break up in walls while still being effective.
@@richardcontinijr9661 .. the only difficulty is finding .223 hollow point right now :(
@@bret9741 try ammobuy.com it let's you search by caliber. They show a website that has Black Hills 50 grain TSX 50 round box for $100 in stock.

I just bought a DDM4 300BLK 16” (I’m in CA with limited barrel options). Thank you for all this info!! It’s exactly what I needed.
How you like it?
im so sorry you live there
Dude this is the best informational 300 blackout video on TH-cam... Now I'm trying to find a budget suppressor..
I’m building my first AR now. Gonna go 300 blackout for home defense purposes. Did you find a good suppressor?
this is probably my favorite video you've done so far. I appreciate a good data dump. And all in one take?! Dude!
😁
Never noticed that the first couple of times I watched this. Nice.
Loved the video. Lots of details and data, as well as, relative comparison between the 5.56 and 7.62x39 rounds. Reminds me of a Paul Harrell Video when he tells you this is the boring part, and that’s the part we love the most. Outstanding information for anyone looking to make a next firearms purchase. Every time I watch your videos I learn something new.
To be fair the effect of decreased barrel length on 300 BO is less than 5.56. That said, longer barrel pretty much always means more velocity no matter the round.
This was probably the most informative video I have seen on this topic. Really appreciate the time spent here. Very impressive.
3rd time watching this. I'm very interested in building a 300blk pistol for my home defense gun. This video is extremely helpful with barrel selection, ammo selection and general info. Really, this is one of your best video's yet.
Did you ever build it? If so, what size barrel did you end up choosing? I'm trying to put on together now. I've got everything except the upper. I can't decide if I want a 7.5, 8.5 or 10.5.... I'd like a smaller options for shoving in backpack or car. But I don't want to sacrifice ballistics.. although according to this vid, there isnt a huge diff between 7.5 and 10.5...
Finally someone who tells it like it is. I got more answers to my questions in this 27 minute video than 27 hours of watching TH-cam videos on the subject. I am a 300 BO fan and have 2 uppers for my one lower. I am also a subscriber now. thx for the info. I reload all of my 300 BO cartridges so I get a bit more range time than the normal shooter. My "go to" cartridge uses the 115 gr. Lehigh Controlled Chaos bullet for "varmint" control. I also practice with 155 gr bullets. I have a 1:8 twist barrel that I fire lapped with David Tubbs components. I was able to get sub MOA groups with the 115 gr Lehigh bullets in the AR platform. I have been watching and implementing some of the recommendations of Grand Thumb in set up. Your video is the icing on the cake!!!!
Good info and great video. You should do a pros and cons or versus video for 5.56, 7.62x39, 300, 6.5 and 6.8.
Great video Mike. I took a hog in Missouri with my 16” barrel .300 BO rifle with a pistol length gas system using 125 gr. Hornady American Gunner ammo. One shot at 80 yards. Hog down and done instantly.
How was the performance for you vs hog gunting with .223?
I consider you one of the most informed and best in youtube when it comes to information on firearms and everything related to them. Thank you Sir for what you do.
The thing behind 8.5 or 9 is that the round achieves full burn at those barrel lengths but it will still benefit from a longer barrel since the gasses behind the round are still expanding even up to 16 inches
One of the best aspects of the Blackout is that there is such a wide range of bullet weights that lets you match velocity to your barrel length.
For HD I'm running a 8.3" 300blk with 110gr Barnes tac tx and a Dead Air Sandman S can. Amazing setup, amazing round!
I wonder how loud that is indoors.
@@ssspencerjr I've shot it outdoors without ears on and it's doable. Indoors I'm sure it would hurt, but if I had to pop off 10 rounds I don't think it would cause permanent damage which is why I went with this set-up.
@Nick 718 Yes, I found out the hard way it doesn't stabilize Hornady 190gr Sub X rounds. Tore up my can and had to send it Dead Air for repairs which they were great about.
@Nick 718 It runs lighter grains perfect, and I've shot about 100 220 grain Hush subs from Freedom Munitions prefect. I just picked up 100 rounds of MagTech's new 200 grain subs but haven't had the chance to try them out yet.
@Nick 718 Yeah I was pissed to say the least! Now I make sure to test out new ammo without the can on first 😂 live and learn! I'm planning on making a video about the experience and will test out the new subs on it as well
One reason you may want a 16 inch 300 blackout is legal issues. In Florida you can have long guns loaded and openly displayed in your vehicle but pistols must either be on your person or locked in a container. If you want a truck gun in 300 blackout it would have to be locked in a container if the barrel is less than 16 inches.
Also, with the pistol brace rule from the ATF all of your 300 Blackout pistols are now illegal or you have to ditch your brace or have to be registered with the ATF.
I cannot say enough about this cat. He is like an interesting teacher plus a great self defense buddy
thanks 😂
I have a Wilson Combat 18" Barreled upper its accurate and I've taken a few hogs with it. I have found that once you get up past 150 Gr bullet weight the projectile drops significantly and you need at least a 30mm scope if your shooting at longer ranges or you'll run out of elevation adjustments. I like to stay around 110 to 125 gr bullet weight that seems to be the most optimum bullet weight for hunting.
Have u used it for deer?
I love my 300blk and i always use the lighter ammo for that extra velocity and energy .
I as well - I have settled on the 115gr Lehigh Defense (Controlled Chaos) = Fragmented Bullet - so there is mostly never a big issue of over pentation and going through walls & hitting a family member. I have 6 pre-Loaded 30rd mags for Home SD - each mag contains 20-CC rounds & 8 -194gr Maximum Expansion rounds - placed through out each magazine.
Hunting mainly Wild Feral Pigs & other annoying Predators - I choose the 110gr & 120gr TAC-TX.
My range is only out to 200yds with my Holosun HS510C - This is Perfect for my needs! -- I don't pretend to be a wanna be sniper - the 300BLK & 200yrd range is ideal for my physical capabilities.
Lastly for the Moment SHTF - My son & I have more then we can carry (30round mags) - loaded with a variety of 110gr to 147gr. (What ever we could find over the past 15yrs. We both shoot via 16" barrel - Mine has a 1-7.5 twist.

How?
10.3/10.5 inch 5.56 for general use and 7.5 inch .300 for home defense
Thanks for answering my question! I’m glad to see that I was on the right track on something I have little experience with. Obviously, there is a ton of information I will need to continue to research.
🇺🇸
Correct me if I'm wrong but the 308 boat tail bullets are more aerodynamic too than Soviet 7.62x 39 .
Talk about a guy who really knows his stuff... excellent video. I own a BCM 9” 300 BLK I use Gorilla’s 110 grain Varmageddon and Hornady’s Black 110 V-Max for self defense, home defense and most other situation along those lines. Subsonic end, Gorillas Silverback 205 grain and Hornady 190 grain Sub-X. Practice ammo is Sellier & Bellot 124 grain FMJ and 200 grain FMJ. Using an AAC 762-SDN-6 suppressor I can say I’ve ever had an issue running any of the ammo mentioned above. Also just in case from my experience mentioned above, the BCM 9” that I own came from Bravo as a 1:7 twist and buffer which I believe is an H1 buffer weight for anyone concerned about not stabilizing and or feeding issues. No issues at all suppressed or unsuppressed. Thank you so much for all your videos and work that you put. We greatly appreciate you my dude!
The recce? I have a BCM recce 9. I totally agree with your comment. I watched some videos today going over buffer weights. They seemed to think if you shoot suppressed the buffer should be an H2 at least. But I haven't had any problems with the H1. I thought about putting in an H2 because they say it'll help some recoil (not that it's an issue) but nothing to do with the cycling using a suppressor. The only issue I've had at all with the gun is because I bought 1k rounds from a guy who loads. Somehow on a few of them after the primer is fired it comes out of the round then gets stuck between the bcg and the lower jamming it up. Other than those shitty rounds it's pretty solid
Ive come back and watched this video 3 times now. One of the best videos you’ve made @mrgunsngear . I wish youd make a part two of this video where you’re comparing the accuracy and range capabilities of the 300bo cartridge offerings out on the range.
Thanks for the info. I am working on a 10.5" build right now and you answered many questions.
All this time later, are you satisfied with the 10.5 or do you wish you got a different size?
@evanclark6547 oh wait this is 300blk. I have a 9" MCX now. Amazing gun.
Thanks for all the effort you put into your videos. Definitely good stuff with no fluff. Very much appreciated.

Why would you have a 16" 300 blackout.... because you live in California
Or you hunt. Or you cast bullets, cause you like to shoot alot for cheap, but still want decent performance.
Or NY 🤦🏼♂️
Are AR pistols not sold in CA?
Jason J. Ayala P. LMFAO Brother, we can’t even buy gen 4 or gen 5 Glocks because “They’re not on the roster” of approved pistols. It’s literally why Glock is still manufacturing new gen 3s
@@smith8124 Thanks. Been studying CA laws this past week. Fun stuff. Didn't know about the gen 4/5 stuff.
I'm absolutely new to 300BLK, I have learned many many things in this video and appreciate it very much.
In my country a semi-auto in 300BLK is easily available but 5.56x45/7.62x39 is harshly regulated (like a class 3 in the U.S.A) and the minimum length for the barrel must be 18", finding informations for long barrels in 300BLK online was complicated and depressing, this, again, was really useful thank you a lot Mrgunsgear, watching another of your video also compelled me to buy a "lock" for my Beretta 1301 bolt release to avoid the dreaded turbo-jam.
Regards.
Thanks, from all of us 300 fans. The Gorilla ammo is great, and I've invested in the copper rounds too. 16 inch barrel, supersonic. Works great. Mine is strictly for defense. I appreciate all the research you did on this.
Built. Finally. Took me 2 months, first build from scratch. Can’t tell you how much this channel has helped me learn. Now time to play super super while I wait for the government.
Funny how these things just turn into either or conversations. Just get one of each!
I will say though, my 8.5" SBR in 300BLK with subsonic & can is obscenely fun.
I'd love to see a gel test comparing a couple .45 acp rounds versus .300 AAC subsonics
Federal HST+p 230 grain rounds hurt your hand while shooting with a handgun. I know 300 BO has better terminal performance, plenty of videos discussing that. But I would definitely consider a
.45 pcc with +p rounds for self defense.
Thanks a lot, finally someone who understands 300 BO supersonic ammo. Love the Barnes 110g black tip.

By far the BEST 300BLK video on the internet.
Hi. I love so much your very informative and educational videos. Could you make the same detailed video for barrel length velocity/energy for 223/556 as they are also so popular these days?
This is going to be my go to referral link any time someone asks me questions about BO from now on.
Man what a thorough presentation. Excellent job.
Yeah everything is a tradeoff, but I think the handiness/maneuverability with a suppressor is worth the slight loss in velocity. A case for 8-10" barrels
That and portability and concealment. A small AR pistol is very convenient to wear in the woods.
Yeah, I think I must agree.
I had a friend ask me about the gas mileage with my Dodge Hemi pickup I told him if I was worried about gas mileage I would have bought a Neon same applies here. I shoot enough to be proficient but not enough to worry about cost, besides I reload so I can shoot a lot on the cheap. I know some don't have the time or confidence to reload but it ain't rocket science and a lot of fun.
Wow. It's really rare to find information of this depth and quality on a youtube shooting channel. Thank you very much.

@@Bajajaba480 im doing psa 300 blkout with a red dot
I choose 16 inch barrel for more velocity, better terminal ballistics and general purpose usage.
I bought an AR earlier this year (300 BLK with a 16' barrel). People in an AR group I was in on FB were talking trash about the barrel length. From what I understand about this caliber and why people buy shorter barrels is because they generally use a can. I have no intention to buy a suppressor. I cared about having something that packs a helluva punch up close and can still pack that punch at some distance. I also caught a really good deal on the gun.
Great info
He toughed it out in Dallas to shoot at PA’s range day during NRA convention. Nice guy.
I know I'm late to the show on this video, but I'm just getting into 300 Blackout. This video was VERY helpful. Thank you.
Next, compare it to 6.8 SPC and 7.62x39; the 300 Blackout will show it's true colors. Good for short barrels and good for suppressor use, but when you start using longer barrels, there are better cartridges.
@Nick 718 While 300 Blackout wasn't intended for longer barrels, it, like all other calibers, do benefit from longer barrels. 6.8 SPC was also designed for CQB, and it achieves that and then some; the ballistics are better than 5.56, 300 Blackout, and 7.62x39. And while we're talking about it, no, 300 Blackout does not out perform 7.62x39; when comparing similar grains, 7.62x39 has more energy than 300 Blackout or 5.56 62 gr green tip at 300 yards.
Hell yeah man thank you! This is exactly what I needed to hear 👍
Love 300 blk in a 16" rifle config. 110gr barnes out of it are vicious
nice
Agreed it’s a wicked round
I'm using the same setup for several years now, very effective. I think of it as the modern modular 30-30. Great woods gun.
Ian Mather why not just 5.56? cheaper and more velocity and more flat shooting.
Nick rockz a 5.56 is flatter shooting and cheaper. But, I rarely shoot beyond 200 yards because I don’t see game at longer distances here in the Texas brush country. Within these distances the.300 is measurably more effective on game.
To Start right off, I don't do a lot of Human hunting anymore....(former XVIII Abn Spcl Warfare SkyDragon here, waaaay back (VN))so when I built my *first AR* style (back in the 'old' days, AR's weren't worth shit in the bush-but they got better) I went for the 300BLK, but also built it with a 20" barrel (kind of amazing what a decent reloader can achieve with this set up). I can make single round reliable game kills up to around 250 yards or so under 'field' conditions (no bench rests lol.) With a good rest of some kind, bout a 100 to 200 more depending on other std enviro concerns...wind, temp, altitude, lighting etc. With a good bench, and the time to dial in a good scope, I can punch paper out a fir distance more than that.
This vid was very helpful for deciding the final specs for my build. I finally finished it, tested it at the range - and it worked! Thank you so much for getting into the specifics!
I've been researching my next gun/parts quite frequently and this covers so much of what I've been curious about. Thank you for this great information, sir.
I have 8 deer in the freezer which are proof of the effectiveness of the 125gr Nosler BT out of a 16” barrel (2200fps). Also, 300BLK supersonic suppressed is MUCH quieter than 5.56 suppressed.
i will watch the entire video because of your shirt alone ! love it. audit the FED!
One of the best videos on 300 blk on youtube
Picked up my 300 BLK pistol from my FFL today. Thank you for the info needed to go down this road. I have some 110gr Noveske with the Nosler Varmageddon bullet to start and the 150gr Fiocchi for the range. I'll now spend a lifetime testing 300 BLK rounds for fun.
The Winchester 300 blk Deer Season XP 150gr round is awesome! Expands perfectly and very accurate in several 300BO I’ve shot it through... 👍🏻
What yardage are you shooting out to? From my understanding, it's only really effective to 300 yards or less.
Adam Huffman 300 yards is really about the limit of any intermediate rifle caliber like 5.56, .300 blk, or 7.62x39 anyway. Honestly, I prefer to cap them all as 200 yard cartridges for an ethical behind the front shoulder kill on a small to medium size adult whitetail deer. Considering the wooded areas I hunt, that’s usually plenty of range. At 300 yards and beyond, I’d rather step up to a true rifle caliber like .308, .30-06, .270, etc. Now, it’s certainly true that deer can be put down with lesser calibers like .17HMR, .22WMR, or even .22LR. You’re talking about critical shot placement into the brain in order to keep a deer from running forever before dieing at that point though. I’m not talking about what can be done especially if it’s taking game for survival. I’m talking about making a clean ethical kill in a non-critical hunting environment.
Im using a 300blk for deer season this year. I also chose winchester 150gr deer season xp. I'm use to a 30-06 with 180gr corelokt so I'm just wondering how those deer rounds worked with your 300blk?
Been waiting for this one! Thank you for taking the time to be thorough.
Lots of effort put into this - appreciate it!
Funny how this was made in March of 2019--which is 5 years before I'm writing this very comment--and I'm watching this literally 2 minutes after ordering a 7.5" .300 Blackout barrel with a 1:5 twist. Thankfully it looks like I made the right decision! Yes, I know you can get better terminal ballistics with longer barrels, but it just seems like the best velocity & energy per barrel length ratio. Man, .300 Blackout is such a great cartridge if for no other reason than how it does *great* with shorter barrels!
I don’t mean to take away from what this video is about. What watch is that you have on? I’m an avid watch collector/lover. Thanks in advance, and this has to be the absolute best and most informative video on 300 blk on TH-cam. Great job!
I keep a suppressed 8" 300BLK with subsonic rounds ready for home defense. And I keep a 16" unsuppressed upper for hunting with supersonic rounds for hunting. And a .22lr dedicated upper for plinking. Got rid of the .556/.223 uppers to mitigate the 300BLK rounds accidentally being loaded into a .556/.223 upper. Only need one braced lower for all of them. Takes up less space in the cabinet, lol
subsonic 300BLK, what advantage does it have over just suppressed subsonic 9mm, in say, a PCC?
@@---tx9xx subsonic 147gr 9mm is 326 foot pounds
Subsonic 220gr 300blk is 520 foot pounds
Not to mention the length and weight of the 300 bullet is better. And it’s much more reliable than a pcc
Excellent info Mike! Very informative.. I’ve been eyeballing the SR-30 in 11.5” to compliment my incoming SR-25 so I’ve got something to share that can with, trying to get as much info before throwing some cash towards the project. This video came in at the perfect time 👊🏼
