6arc bolt gun

[SKWERLZ]

It's fine to disagree. Here's a pic of the difference. That's literally it!. The only difference is that ppc shoulder is .045 forward on the ARC. Otherwise, they are identical.

So closer to 22 arc length

So closer to 22 arc length

Yes, barely. The 22 ARC is exactly a 22 Grendel and the shoulder is an additional .030 forward, so .075 longer than a PPC. Different prints may show it as .070 but you get the idea. The 6 Arc is in between a ppc and 22 ARC(Grendel). So yes, you are correct that a 22 ARC is longer than a 6 ARC

I've been pretty fortunate competing in sr br with a 6 Grendel for several years now. I can load it just like a ppc but can get slightly better speeds if I step on it a bit. I can't say that one is better than the other. They both flat shoot. Started shooting a 22 ARC last season but haven't had time to get to know it well yet. It's bad fast though, in a bolt gun. With the right powder, pretty sure I can get 55's to 3900fps. I've seen 3830fps so far and it shoots but hard on brass with n133 at that speed. I'll play with it more soon. That's not book data, so work up with caution and certainly not in a gas gun.

The 6ARC is shorter than the 6.5 Grendel. To sidestep the established 6mmAR (aka 6mm Grendel), Hornady barely tweaked the case geometry so that it could rename … I mean name its newly created proprietary cartridge. With the 6ARC being shorter it eliminates the potential risk of loading a 6.5 Grendel into its chamber and closing the bolt. Lesson learned from 300BO fitting inside chamber for .223/5.56 and blowing up barrels.

Unlike the 6mmAR, there really hasn’t been an established .22 Grendel in the market. Hornady simply necked down a 6.5 Grendel and named it 22ARC. This is why 22ARC is longer case than 6ARC.

I have this one.

View attachment 1651652

It is a Savage 110 action with a Shilen 28" Bull in 7.5 twist Four groove. It is shooting 105gr Berger Hy-brid bullets over Leverevolution powder. Running at appx. 2780fps. It is used for a target league at ranges of 100 to 300 yards.

For a varmint gun I would most likely go with a 22" Varmint weight barrel with the 7.5 twist. Have not really shot any factory loads so I cannot comment on that.

Dadgumit.. I had about talked myself out of rebarreling my 6ARC with another 6ARC barrel. And then you throw a picture up of that beauty.

Hi Txbowhunter409, how many rounds did you put on the 1st 6arc barrel and is it shot out? E.

It has 180 round on the barrel.

So you haven't given much detail on the rifle you are fooling with. Tell us more.
Action, barrel, stock/chassis.

That rifle I posted, I purchased used and it was supposed to be a very low round count. Since I reload, I put together a good number of test rounds and factory rounds. Never could get it to shoot. After barrel change, shoots light's out.

Another I know is shooting a 20" Varmint profile, suppressed, lighter factory loads using a thermal sight for dogs at night. Very successful with it.

Oh the rifle was just an experiment and intended to be a plinker. Cheaper to reload for, less recoil and according to some, extremely accurate.

The gun itself is a Brownells Howa mini barreled action. Hell I have more in chassis (MDT Oryx), Jard trigger set at 0.3 ounces, Leupold rail, Vortex rings, Athlon scope, MDT Oryx bipod and Silencerco ASR muzzle break. So nothing fancy, but definitely more than what the barreled action cost.

If you were building a 6arc bolt gun, what barrel length and twist rate would you go for on a dedicated coyote rifle? Majority of my shots are 80 to 150, i don’t I’ll ever be able to shoot past 300 in my area.

Is there any good factory ammunition? I don’t like to blow big holes in them.

I won a custom rifle and I’m drawn to the 6arc

I'd build a 1/9" twist. 20" bbl. Run 65g to 95g bullets and it will drop coyotes all day accurately.
Kinda like my 6x6.8 builds and I run those to 600 yards.
Don't need a fast twist or longer bbl

I have a Savage 18" 7.5 twist that shoots very well .5 and under. I shot a moose with it at 100 yards in the neck and it dropped like you hit it with a hammer in the head.. 6 arc is definitely not a Moose gun but it went through the entire neck and was under the hide on the far side 108 hornady
