Real world 6 arc speeds

[Jake Leibke]

Looking at getting a 6 arc bolt gun 18” barrel. I’ll be reloading for it. Looking for some real world speed numbers. Specifically with 95 tmk’s but welcome all data points.

Sierra lists 3000 fps with a 24” barrel. My experience with the 22 arc and Hornady data shooting the 75 eldm at max listed load I’m getting very close to the speed shown but out of an 18” barrel. Can I expect the same type of results with the 6 arc?

Didn’t see a threads specifically for 6 ARC, so figured I’d get this going for people to share velocities and barrel lengths on their 6 ARC. This should help folks get a baseline of what to expect when they are considering building one.

16” Proof stainless AR barrel, suppressor, factory ammo. Accuracy was about equal between the factory 108 eldm and factory 103 eldx. These are the first shots down the barrel so I am expecting them to speed up and settle in a little.

I have a Howa Mini 6 ARC with a 20" barrel. In my load testing with the 95 TMK I was right around 2750 fps with both TAC and 8208 XBR. With an 18" barrel I bet you would be just shy of 2700.

20" Howa with Hornady Precision Hunter and Match Ammo are in the 2650 range.

90g Accubond Handloads - 2,950 TAC powder, bolt gun data.
