This just goes to show that not only are FMJ subsonic bullets just for plinking, but so are OTM subsonic rounds.

And at the very least, Hornady Sub-X (but even those leave a good bit to be desired)
So happy to see this test! You're doing gods work. I haven't watched video yet, I hope this ammo does great, I want AAC to succeed sooo bad. Hopefully they'll crank out 7.62x39 steel cased. Ok, so I watched your video. I know whats wrong with your group sizes. 1 in 8 twist is not enough for those 220gr bullets. You should repeat test with a 1 in 7 twist. I think that will help. Might even cut group size in half.
I’m not a ballistics expert by any means but it looked like your velocities were all over the place one was in the mid 800s and the other high 900s all for the same barrel length conversely your group spread seemed to be wide up and down which to me denotes and backs up the point that the inconsistent velocities may be the reason the groups were so bad. I looked back at the groups and left and right they were basically in the same area minus maybe a bit of user error.
In my experience, 1/8 twist will not yield very impressive accuracy with heavy subs. 1/7 is better but also not super impressive. 1/5 twist gets factory 220gr to about 1.5-1.75 MOA in my use case. Handloads get close to 1 MOA. I think this is due to a couple of factors, first being that the expanding gasses impinge on the rear of the projectile more severely than would be so in a supersonic application. This will induce a slight wobble to the projectile. This is also why groups generally seem to tighten when supressors are used with subs, as supressors slow the gasses down. The other thing is gyroscopic stability. The faster the projectile spins - construction and materials strength permitting - the more stable it can be. Gyroscopic stability factor for 220gr SMK @ 900fps 1/8 - 1.97 1/7 - 2.58 1/5 - 5.05 Food for thought
I just put a 300 Blk build together and I’m glad I did my homework regarding the twist rate. I’ve seen multiple people online talking about how a 1:5 twist is pretty much required if you want to accurately shoot subsonics. Credit to the people at AAC (and now Q) who seemed to first discover this, hence why the Honey Badger/etc have it. Thankfully now some more 1:5 options have become available-Faxon, Black River Tactical, Tactical Kinetics (albeit not direct from their website for some reason), and Ballistic Advantage to name a few.
@@archipelago93this is just not true😂 only if you’re going super short, is it true… think about it if you have more rifling you’re getting more spin… what he said in the video is true…my 9inch barrel gets 1.5 moa easy with these rounds with a 1/7
For 300 BLK, me personally I’d shoot the 110gr copper TSX like bullet. If subsonic is your route there’s a couple expanding copper subs that I believe still penetrate 12”+
If you want a dedicated suppressed, subsonic carbine for defense you would be better off going with a 9mm or .45acp. For example 147gr 9mm Federal HST has better terminal performance than just about any subsonic .300blk.
Well, think about this... for close quarters, you can achieve 150ft/lbs more muzzle energy with a 10.5" 300blk and a 110gr V-Max (or 110gr Barnes TAC) than you can with a 20" 5.56 shooting M193. For home defense, nuff said? Lol
I have a 7.5" 300bo SBR. I run 147gr for plinking and 220gr Hush ammo for low db levels and HD. I don't know if its your mic or the ammo,but my rig with 220gr Hush ammo is definitely more quiet ,just comparing videos.
I run the 220gr Hush too and like it. Very quiet, but cycles my 10.5" with or without a suppressor. It's very smokey, but i like the quietness and reliability.
These bullets are supposed to work at low velocity, most Guy's are having the same results, over penetration flying out of the block sideways. Nice work Buddy ❤
Ammo Inc 220gr StelTH ammo shoots extremely well out of my 1:7 twist 300BLK. PSA sells it as well as other places. Currently on sale for $0.85/round. StelTH 147gr 9mm is nice also.
I ensemble chip ar15 with BCA upper ss 20" Barrel and PSA lower and with this sierra mach ammo 220 make 1 1/2" group @100 yard all time . that is perfect for me because I not hunt more that 150 yard.
I bought a bunch of these AAC 220grn from psa and every single one gets jammed in the chamber in both 300 blackouts I have. I’ve had the gun checked and every other brand 220 grn works flawlessly. The casings have excessive wear from being chambered once then I have to mortar the charging handle to get them out. Not sure if it’s a bad batch or what but both firearms have higher end barrels so I’m at a loss and have a bunch of money worth of ammo I can’t shoot or return
@@BuffRANGEI could be wrong but I thought psa had a thing saying no returns on ammo but I emailed them anyway to try to start the return process so we’ll see.
@@chrisfly777300ER Indeed I know that's what you meant. Even so that tumbling needs to happen very very soon, like 1-2" in, and I don't personally see that happening. But at some point if I get more of their 125gr we can try to test it
Twist rate matters, especially for Subs. You need a 1:5 twist rate for subs, granted very few manufacturers do that twist rate... however, Black River Tactical does.
Not true my 1/7 8.5 inch runs these 1moa at 100 yards… this guy either doesn’t know how to shoot or it’s his upper because no way it’s that round I’ve shot that load many times and it’s very accurate. SMK is a proven load there’s nothing to debate in here. And you only need a 1/5 twist if you’re going super short like under 8.5 or 7.5
@@mrgrump2534exactly. At distances under 300 yards, twist rates between 5 - 8 aren’t usually even noticeable unless the velocity is really low due to a short barrel.
AP by whos terms ? Military or in general anything with a core or penetrator designed for armor work? Defeating level IV first strike without a purpose built projectile is not easily. A heavy magnum rifle round like 338 Lapua or 300 Win Mag would impart a LOT of energy on a plate that’s hard to handle but may not break through the plate on the first shot.
@@BuffRANGE in terms as in a civilian purchase i know i can get ss190 that can punch through cheap level 4 but its hard to get without an ffl or being police (thank you for commenting back you make great videos)
@@Unsername6785 ss190 is 5.7 and it’s ability is limited to level IIIa pistol armor :) commercially your best ammo choice to defeat armor is to keep shooting the same area :)
I really hope AAC, hell any company, comes out with a projectile in the 190-220 grain weight that’s not match grade for bulk 300blk. I get it that it’s another sku and all that’s associated with it, but there isn’t a need a match grade projectile for range ammo when most of us are just blasting it for fun.
It's a shitty short barrel, less pressure, it doesn't have time to transfer the energy needed to recharge the charge. I assume. I'm curious how it will go with the silencer, there the pressure in the barrel should hold a little longer. Hope this helps. Or choose gunpowder with a shorter burning time and higher pressure. In any case, a bad choice for combat or homedefense. Shooting like this, I'm already dead. Manually load cartridges into the chamber.. never. The cartridge is obviously suitable for another weapon. I am from East europe... here we use good old AK-47 or SKS. Hard-chromed barrel, does not jam, can withstand mud and snow. Can take a shot underwater. I saw a video where a guy shot from a depth of 1m at a mannequin on the pier. It was a nice shot, the projectile went through the head like butter. Without noise, of course. These .300 BLK cartridges look like a copy of the Russian ammunition used by the Russians in a very old military silent sub-sonic sniper rifle "VINTOREZ". If someone comes up with something better for survival, I'll definitely buy it.
I shoot other loads with this same bullet. I've never had a round ricochet as easily as this. It will bounce off of plain dirt and go flying for a mile.
1:8 twist isn't enough for heavy pills. I'll be swapping out my 7.5inch 1:8 PSA barrel with a Faxon 6.5 1:5 twist shortly. I can't get any subsonic ammo to group better than 3 in at 50 yards.
@@BuffRANGE faster twist should better stabilize heavier bullets. So in theory a 1:7 should be slightly better than 1:8 and noticably better than 1:9. The 1:5 is purpose designed for 175gr+ bullets.
@@BuffRANGE You most definitely should use at least 1 in 7 twist rate. ^^ I had remington 220s leaving ovalish holes at 100 yards with a 10 inch barrel.

@@mrgrump2534 It does matter, when the bolt is unlocking, a 'DI' gun has way more gas from the gas tube, gas key, bolt tail, and carrier gas ports. A piston gun has none of that, only back pressure from the bore. Did you ever see a DI AR blow through a thick wall of mud cake on the port when unlocking? A short-stroke piston gun like HK416 doesn't do it; a long-stroke AK doesn't do it either.
@@mrgrump2534I agree. Most of the gas blowback from a suppressor comes from the barrel when the bolt opens. It can be even worse in a piston gun because less gas is allowed to leave the barrel into the piston. The gas from the gas tube into the bolt carrier is vented out the side of a non-piston AR, and then closed off when the bolt closes.
Factory subs are usually made to be subsonic out of 16” barrels, but it does look like these are slower than they could be. But, they also had crazy velocity variation, and at least one was almost super.
That accuracy and gel performance is a perfect example of how subsonic .300 blk should be considered more of a pistol round. Some subsonic hollow point pistol rounds actually have better terminal performance.
Military Arm Channel has a pretty good demonstration showing the difference in terminal performance of a 5.5" 1:5T vs more traditional BCM 9" barrel. With subsonic loads, the 5.5" barrel performed MUCH better, likely due to the rotational energy of the tighter twist rate leading to greater hydrostatic shock. A number of other videos have shown the same thing. th-cam.com/video/rTxhMFqzqV0/w-d-xo.html
At subsonic velocities that "rotational energy" transfer stuff is very minimalistic compared to the same subsonic at slower twist rates. Someone on the 8.6 BLK forum calculated it out and the "energy" per say was not leaps and bounds.
That was probably just a roll of the dice: one bullet happened to yaw in the watermelon, and the other didn’t. It could just as well be the reverse in a second test. Realistically, it should be expected that a bullet with a slower twist would yaw sooner than an over-stabilized bullet from a tighter twist.
This just goes to show that not only are FMJ subsonic bullets just for plinking, but so are OTM subsonic rounds. For people using subsonic rounds for home defense, it is a MUST to get more expensive expanding ammo, especially copper expanding ones such those from Lehigh Defense or Maker Rex. And at the very least, Hornady Sub-X (but even those leave a good bit to be desired)
