Anyone out there shooting 6mm ARC?

[sell33]

I’ve been reading and researching on 6ARC. There is almost no content on here about it. Anyone have any first hand experience with it?

I am thinking of building an AR in it. I think it seems about perfect for an AR style varmint/deer gun without stepping up to an AR10.

I reload, so not super concerned about ammo, though finding a box or two on shelves once in awhile would be nice.

I ordered a Proof Research barrel as soon as they were released. I wanted a longer range Varmint cartridge for coyotes. No complaints. I am not a re-loader, but I think someone that did re load could really optimize the performance from this cartridge. The 108 and 103 grain Hornady all work for me. Biggest downside, it’s loud! Not running suppressed…yet. That said, I’m not shooting a high volume of rounds.

ARC is on the left.

Isn't this basically a 6mm Grendel? Another cartridge based off of the 7.62x39mm case?

IIRC they are basically the same out to 500yds then the 6.5 Grendel takes over.

I would go with the one that has the most available ammunition and best price for it and if you reload components.
I doubt you'll find much difference between 6mm ARC and 6.5 Grendel.

I wish I had the funds to have/own/stock/shoot it! :-D

Yes. I shoot it in AR. I reload 6.5G brass into ARC and shoot fast 65-70 grain loads. Smashes wild dogs on the spot.

Long before 6mm ARC, there was the 6mm turbo, close to the same thing but he didn't have the big name behind him

I campaigned one in high power competition for two years. I sold it after it broke the extractor the second time. The bolt face/extractor have to be hogged out to accommodate the larger cartridge.

I’m putting one together myself. It’ll be a little while until it’s completed.

What twist rate? How many fps are you getting?

I have a buddy that built an AR in one and he loves it. I was seriously considering it before I built my 6.5 Grendel, and probably would have if ammo was more available and cheaper.

The larger bullet also factored into my choice since I only hunt deer with it. If I didn't have a varmint rifle already, I would have leaned harder towards the 6mm ARC as well.

1:8 20 inch. 65 bullets at 3265 on benchmark. 70 is 3082 on CFE 223 and 3150 on leverevolution. SD from 5.8 - 14.3.

Been shooting the arc in a bolt gun for about a year. I love the caliber I did just also build a gas gun for it. So far playing with heavy 105+ projectiles. It really likes extruded powders for low es/sd numbers. But higher velocity with ball powders. I have found varget, RL-15, benchmark to be good. But best accuracy was 8208 xbr. Lever evolution, powerpro 2000mr, and cfe .233 gave best speed. But es/sd numbers weren't great. Also barrell length should be given a lot of thought. An inch of barrell is huge in arc for speed.
