I’ve told You in the past that I like the way You load. You don’t waste bullets. You don’t waste a lot of time. I like Your systematic approach. Also, I appreciate that there isn’t a bunch of foul language. THANK YOU. I appreciate You!
Agreed. I been crying over the lack of content on 6mm mongoose for a while now but I guess arc is what people are willing to take mainstream. The 6mm mongoose actually can match velocities by the inch but you can use your 223 bolt and mags. Oh well, the fate of a wild cat
Hey Jeff totally agree with Johnnys professionalism and no foul language, his videos are very informative to us reloaders. Keep up the great videos Johnny
Very encouraging. Really appreciate all the time, energy & resources you are putting into these tests. Great job. Excellent data. Liking this chambering alot.
Thanks for the writeup Johnny - I've been sticking with 105Bergers/W748 and 105Bergers/LeverLoution. Problem right now is brass. I've been making PILES of 6ARC brass from starline, just processed 220 cases yesterday and have another small pile to go. 223 YOUR FIRED!!! - I dumped 223 loading.
This is some nice content. I've been loading for about 30years, wish I had time to do tests like this. I have a 6DTI upper coming and am having a good time checking out all the similar 6mm AR cartridges. 75grv max and Benchmark is going to be my first try. Really wanted to start off with H4895 but the stuff is not possible to find. I considered the 6mm ARC but the DTI/WOA/6x6.8 has a little higher velocity with the 65 to 85gr bullets that I will be using. Nice shooting BTW
Speaking of short throats, i have been loading for my new M70 270Win and just the other day checked my seating depths with a Hornady modified case (should have done this from the start). The listed seating depth on all 3 bullets i have tried so far have been longer than my throat’s maximum. I had been testing all my loads just to find out i had been jamming every single one into the lands, some as much as 0.075!! The gun shot decent (not great) and didnt show any signs of overpressure on the cases, even going above max listed loads. Crazy. Just shows that before you EVER load up a single round, CHECK YOUR THROAT! Even factory Fed ‘blue box’ ammo was jamming the lands.
Shooting like this, We try and alleviate the variables. I’ve been using the same Rockchucker for decades. I never would have thought a press could be a problem, as long as it was a quality build.
Congratulations 👏 agin on 100,000k Awsome video on light bullets must guys loading heavy 103-110 gr. Love the noslers in 243win. Winchesters use load them factory as Ballistics Silvertip. Actually just pick up a box of nosler Silvertip Ballistics at local shop to load for 243win in 95gr. Also had the original purple tip 90grs. Also had some ttsx all coppers
I enjoyed your video and results. I bought ammo (Hornady Black) because 6mm ARC brass is unavailable. I look forward to seeing how my new 18" CMMG barrel works on my newly constructed AR-based gun. I am going to try Win 748 just because I have a ton of it. I have a bunch of bullets to try from that are from 80 to 95 grains.
I run the 75 and 87 grain vmax in my 243 over IMR 4451. Get 1/2 MOA groups from both bullets with that powder. May be worth a shot to try in the 6mm arc as well. I'm headed this weekend to test 90 gr gamechangers in my 6mm Creedmoor.
My Hornady brass makes the same smear and sometimes burr in Grendel, way below max loads. The Starline, in comparison, doesn't seem to show ejector marks nearly as easily.
@Johnny's Reloading Bench - In my reloading 6.5 Grendel using Hornady brass I've had some issues with the cases stretching and showing signs of case head separation within 3 to 4 firings where others in the same lot have made it to 6 or 7 firings with no problems at all. Another TH-camr who goes by Hazzbro has had the same problems. I don't have a way to test it for hardness but it makes me think some of the cases are a lot softer than they should be. I'm wondering if you have had any similar issues with Grendel or 6mm ARC Hornady brass?
The beauty of the 6mm is, you can change the mission with the grain of the slug. But, 6mm is hampered by the desire to retrofit it into the .223 platform.
Some weird outliers here or there, yeah, there's barely a difference between the two - this is pretty comprehensive! I've been trying to find a way to compare my RCBS Summit Press with my other RCBS press, but it's a lot more difficult than you think.
I would assume the accuracy would be hit and miss with all of those lighter bullets as the 6mm arc is a 7.5 twist and geared toward heavys. Awesome video. Thank you for the content. I just put together a 20in Faxon heavy flute barrel 6mm arc and I am following your channel to help me learn. So thank you sir.
I'm working on a load for my 6arc as well I can't seem to get consistent groups. I feel like my barrel is a bit short to the lands but have only measured with the hornady coal gauge I've tried 223 and lever Rev for powder and I have tried 80 sierra varmiter 90 nosler accubond and 95 nosler bt. Even the 3 factory loads don't group. Thought it was my suppressor at first so I have been running without it. Main question is do you clean between groups or run all those shots without cleaning? Any other advice? Thanks! Keep the videos coming!
I know this an old video but what others and I have found is ejecter swipes in gas guns are just how this cartridge behaves. Even with lighter loads. Its more a timing issue rather than loads being too hot.
6mm ARC! I finally found ammo for mine...wish there were other companies making the brass. Maybe try not wrapping your thumb around the back of the grip...just rest it to the right side like a bench rest shooter. I find that gives me a more consistent trigger press.
The non-uniform tips will cause slight variations in BCs. While muzzle SD may be quite consistent, down range each bullet will be shedding speed at a slightly different rate. This probably doesn't account for much of your deviation between muzzle SD and 100y SD, but it certainly will have an effect, and becomes more pronounced the further the distance.
Give N550 a try, having good luck with it. I started at 30 grains with the 90 gamechanger. Haven’t tried it with the heavies yet but my speed matches leverevolution
@@jmkhenka Hornady brass is not crap you are comparing hornady to the best brass you can get. If you think hornady brass is crap use winchester or remington, or any other popular ammo manufacturer's brass they are shit compared to hornady.
Hey Johnny I got a question that would be great if you can answer it. I want to build an AR for long range and hunting. Which do you recommend? 6mm ARC or 6.5 Grendel. Thank you.
Do the long seating depths from the manuals cause loaded rounds to get stuck in the chamber? My 75gr Vmax are getting stuck and I'm mortaring the bolt open.
How about the 85gr TSX and 90gr GMX. I haven't found anyone working up lead free hunting loads. I'm especially interested because Savage will be offering their Axis II bolt gun in 6 ARC later this year.
Congrats on the subs.... How about a comparison of the 6 ARC vs 6 PPC? Maybe take some 68 Barts and compare velos and accuracy with charges of N133, BenchMark, IMR 8208 seated the same off the lands? While not a BR gun per se, I bet your AR in ARC could do reasonably well.
Yep, my dad was a .243-win shooter and I have a boatload projectile to shoot. The most of them are 85-90 grain and wasn't sure if 6mm ARC was for me. I am 6.5 Grendel fan and will stay one. I guess I will be looking for a new barrel and get the dust off of the boxes of .243 bullets. Get job on the ARC
For the most part all the projectiles show promise with som minor tweaks and maybe drop some of the fast powders. The heavier V-Max is what I want to work on.
I'm behind the times..oh well..Benchmark is excellent powder with the correct percentage of case fill. 8208xbr excels right above high pressure signs,hard on brass with best accuracy loads
Says something about Arc when you can grab 10 bullets a random charge weight of 10 powders and get 1/2 of them to shoot under 1 moa. And I’m betting a couple more were the result of a loose suppressor or switching dies. Can’t wait to build one
Q: How do you go from extremely excited to extremely disappointed in no time flat? A: You find primers online from a dot com site that looks American, but then scroll to find in bold print: "Will not ship to the US."
I wouldn’t read much into these groups. They were just fire forming loads. It still remains to be seen, what JRB can squeeze out of each of these bullets, with proper load development.
Maybe try resizing some starline 6.5grendel brass down to 6arc? I had bad ejector swipes with hornady brass even with mild loads for 6.5 and 22grendel. The 6.5grendel starline brass has been much better. Seeing everyone's success with 6arc has me thinking about selling my 6.5grendel.
i know this is a little late, but did you ever find out why your brass got so messed up? my hornady brass also got really beat up with loads that should have been well under pressure. (6mm arc, 87gr vmax lvrevo)
answer me this, you said 2 different presses, wouldnt you think more of a difference woiuld be from the dies and the bullets, such as the bullet might seat different bc the ogive or bullets are not exactly the same. what i mean is i know for a fact the COL could be different from each round just bc of the bullet and how the die seats it?

“Let’s not screw it up...put that last shot right in the middle.” The kiss of death.
Premium production quality as always. Thanks for the 6mm ARC coverage!
Congrats reaching 100,000 subs! It was a pleasure watching you and I learned so much. They say the first 100,000 subs is the hardest. Cheers!
Hey Jeff totally agree with Johnnys professionalism and no foul language, his videos are very informative to us reloaders. Keep up the great videos Johnny
loving this 6 arc series cant wait for more!
so glad to see you doing the 6mm arc your data is what got me on the 6.5 grendel and I still love it 2 years later keep up the great work
Congrats on100k Subscribers!! Had a good time watching all day on the Live feed. Keep the video's coming on YT.

Great vid Johnny. Look forward to every one ya make
Great info Jonny. Thank you for all that you do!
Yup. Totally agree with you that fast powders spike very fast. One has to be careful. Great video.
Thank you for doing this for us!
Great stuff Johnny !
Your videos are the absolute best in detail for loads and round info. Thanks for the effort you put into them.
Can't wait to see more!
Thanks for recording all your work.

Love to see the BL-C(2) hanging tough. Yup, an older "ball" propellant too.

I would like to see you do the Hornady 103 eldx if you could that would be a great addition to the line up. And try a few powders. If you would!
I would love to see this style of videos done with 22 ARC.
How the heck did you get all the bullets? Love the content. Plus one like
About damn time.. I want to see this in a 16inch barrel with 90grains
Does the 1-7.5 twist like the longer heavier bullets and not the short light ones ?
The beauty of the 6mm is, you can change the mission with the grain of the slug. But, 6mm is hampered by the desire to retrofit it into the .223 platform.
Some weird outliers here or there, yeah, there's barely a difference between the two - this is pretty comprehensive!
I've been trying to find a way to compare my RCBS Summit Press with my other RCBS press, but it's a lot more difficult than you think.

Ha my Uncle used to work at Sierra back when they were in Whittier.
6mm ARC! I finally found ammo for mine...wish there were other companies making the brass.
Maybe try not wrapping your thumb around the back of the grip...just rest it to the right side like a bench rest shooter. I find that gives me a more consistent trigger press.
Come back, we miss you.
With a 7.5 twist barrel I didn't expect the lighter bullet to do as well as they did.
real man real bullet thank god.
I wish there was this variety of powder in the stores. 😥
Good stuff. How are you trimming your 6 ARC brass?
The non-uniform tips will cause slight variations in BCs. While muzzle SD may be quite consistent, down range each bullet will be shedding speed at a slightly different rate. This probably doesn't account for much of your deviation between muzzle SD and 100y SD, but it certainly will have an effect, and becomes more pronounced the further the distance.
Got to keep in mind that these light bullets are loosing a LOT of speed from muzzle to target.
Give N550 a try, having good luck with it. I started at 30 grains with the 90 gamechanger. Haven’t tried it with the heavies yet but my speed matches leverevolution
Looks like the gun likes those 68grains, have you given thought on trying the RCBS Summit press?
I got similar brass damage to my 6.5 Grendel initially. I had to increase the buffer weight/spring to reduce it.
hornbady brass is crap.. my bolt action howa screws up the hornady brass like nothing, while lapua in the same load is fine.
@@jmkhenka Hornady brass is not crap you are comparing hornady to the best brass you can get. If you think hornady brass is crap use winchester or remington, or any other popular ammo manufacturer's brass they are shit compared to hornady.
@@masonkaye5 well we mostly have Norma and Lapua here with truckloads of GGG/seller&bellot...
You should consider doing a gel test of the best heavy and light loads you find; just this one time for the 6mm Arc series.
Hey Johnny I got a question that would be great if you can answer it. I want to build an AR for long range and hunting. Which do you recommend? 6mm ARC or 6.5 Grendel. Thank you.
If more manufacturers would offer ammo for this caliber I believe it would be more popular

have you ever used any Barnes Copper bullets? i was looking at the 85 gr tsx hollow point.

Sd from muzzle and at target difference is atmospheric and bc related I would think.?or just electronics??
I think its clear that the Military should have developed a 6mm round for the m4 platform
can you do a video on the speer 308 168 gold dot?
I have always liked the sierra bullets. I use 165 gr sierra game king for my .30-06 Glad to see a 6mm ARC SGK shoot so well.
The 6 ARC looks like it will be a shooter
For the most part all the projectiles show promise with som minor tweaks and maybe drop some of the fast powders. The heavier V-Max is what I want to work on.
Recent hornady brass has been very soft, like bubble gum soft, I'm only getting 2-3 from my 6.5 prc loading light.
I only got 1-2 firings from hornady 6.5grendel brass. Switched to starline and couldn't be happier.
I was surprised you did not single load the rounds that used fast powder.
I'm behind the times..oh well..Benchmark is excellent powder with the correct percentage of case fill. 8208xbr excels right above high pressure signs,hard on brass with best accuracy loads

How about working up some Ramshot TAC loads?
I’m surprised at the 87 Vmax loads. My 243 loves them, and I know your barrel loves CFE223. Maybe a different seating depth would work better?
I wouldn’t read much into these groups. They were just fire forming loads. It still remains to be seen, what JRB can squeeze out of each of these bullets, with proper load development.
I'd like to see the 87gn v-max with lever loads.
Those look more like bolt-gun loads. You really need a Uintah Precision 6ARC upper for your AR. Incredible, accurate true-bolt upper.
Maybe try resizing some starline 6.5grendel brass down to 6arc? I had bad ejector swipes with hornady brass even with mild loads for 6.5 and 22grendel. The 6.5grendel starline brass has been much better.
Seeing everyone's success with 6arc has me thinking about selling my 6.5grendel.
Did I miss it? What brand of barrel and length did you use? And twist rate?
“Don’t screw it up”
We all know what’s coming next! Lol
Is this odnin works barrel worth 340 dollars? Seems like it is picky on ammo.
Just picked up 100 6.5 Grendel cases, pressed a dozen down to 6 MM ARC.
I shoot one at a time they loaded fine for fire forming.
Accuracy was ok
Ok, you're stating velocity at 3350 and it shows 2875 on the screen. Is that the number at the target??
87 Berger vld it's well worth a shot
Is it just me or did your Grendel in the Faxon outshoot the 6 arc? I'll need to go rewatch the 6.5G series again.
If grendal shoots .75 at 100 yards at 2700fps, how will that compare with 6mm traveling 3300fps after 1300 yards?
i know this is a little late, but did you ever find out why your brass got so messed up? my hornady brass also got really beat up with loads that should have been well under pressure. (6mm arc, 87gr vmax lvrevo)
replying to myself, my barrel was WAY over gassed. turned it way down and my brass isnt bad
I hope you cover the 22 grendel....
OMG my oden works barrel with a borescope looks terrible,it shoots terrible too
Seems like groups get progressively worse till the break at 68gr barts Ultra. I think barrel temp was a factor here
What is the target system you’re using?
answer me this, you said 2 different presses, wouldnt you think more of a difference woiuld be from the dies and the bullets, such as the bullet might seat different bc the ogive or bullets are not exactly the same. what i mean is i know for a fact the COL could be different from each round just bc of the bullet and how the die seats it?
