20 inch 6BR Velocity

[BallisticPrimate]

Hide, I'm trying to get reliable data re velocity numbers for a 20 inch 6BR (8 twist) running 80 & 105gr projectiles. Varget is my preferred powder since I'm sitting on a fair bit of it. Any info appreciated.

Probably whatever people with 26" barrels are getting minus 150 fps. Somewhere around 2800 fps would be my guess.

I prefer h4895, it is good for 50+ fps more than varget. I had a 18" 6br 7.5tw, it ran 2750 with 105 & 107

How much 4895 do you run in your BR?

29.0-29.5

29.0-29.5

Thanks!

You ever run IMR4895 or 4166?

Have a 20” 1:8 Hawk Hill Dasher and get 2825fps with a 107SMK over 32.4gr Varget.

That's excellent velocity from a 20' barrel, I'll have to look hard at h4895, thanks.
