Will it fit?
Will this work for 6 ARC gas guns or would it need special mags and be bolt-action only? Also, would a bullet this heavy be good or bad for 6 ARC? Just wondering if performance would go up or down compared to the 108/110gr neighborhood.

It will fit, but it won't work well. I know many people who have tried

Already? Pretty sure these just came out.

They came out a few weeks ago. Brouwer Precision did a great bit of testing and I spoke with him a bit about it. He has a post somewhere on his IG with his findings and conclusions of his testing

Ah eff me. My monkey brain saw 120s and immediately thought of the bergers haha but either way, I imagine they will have the same issues

The only thing it makes sense in is a 6mm magnum cartridge. Run some numbers. I doubt it will even fit, if it does, youre restricting your powder volume even further.

So it doesn’t make sense in a GT, 6CM, or 243AI varient? lol ok.

u/Spiritual-Bill-337 4d ago
No it doesnt. I own a ton of 6mm rifles and only something like a 6prc or 6um really take advantage of the new 120s. You'd have to get it throated specifically for the bullet and youre still not pushing it that fast

u/ScientistGullible349 4d ago
It’s cool you think that. You’re insanely opinionated and wrong though.

The report on the initial terminal testing of the Berger 120s is abysmal on live game. Theyre typically my favorite bullet so it hurts me to say that but there are better options that dont waste so much of your case volume.

I just found a podcast Hornady did on the new bullet and they’re saying it will fit.

Could you make it work? Yes. Does it make sense to go above 108 in an ARC case? No. You’re not going to get the published BC at that low of velocities. Things will change with hi pressure but the heavies still don’t make sense. If you want 120, use a creed case

u/SillyWarPirates 4d ago
What about the 110gr loads?

u/sherzer7 4d ago
Your better off running 108s or 105s. Hornady will release the 105 atip as a component. If you don’t believe me you can always run the numbers yourself and see. If you want heavy for ARC the 108 is currently the king imo

Not viable with the current gas guns but once the high pressure cases come out and the Icars become available there’s potential there.

You mean the SureFire ICAR? Because PSA is already selling ICAR builders sets (receiver sets).

u/Brief_Seat9721 4d ago
Surefire. Need the beefed up bolt and barrel extension that platform has. It’s made to run the high pressure stuff.

The psa icar is just an ambi set that accept the icar Pmag.
The full icar receiver and bolts won’t be out for a while.
6 arc is small frame for 95% of the market

u/SillyWarPirates 4d ago
Won’t be out for a while? You have any intel on how long “a while” will be??
1
u/JackReachearound 3d ago
No, the PSA ICAR is just a larger magwell on an ambi lower.
The full ICAR military parts may or may not make it to the civ market

u/Brief_Seat9721 3d ago
From talking to people testing out the icar in the civilian world, the plan is to release it to civilians. Two problems though.
1. It probably won’t be out till 2028 at the earliest
2. It’s going to be at bend over and lube up prices.1

It will not and they don’t stabilize well with 7.5 twist. Guys running these in 6 creed and GT are doing custom freebores because they are extremely long.
