Encore 6mm BR ??

[rmist04]

I have ordered a Bullberry barrel in 6mmBR, I haven't given the exact length yet. I looking at somewhere around 18-20 inches in 8 twist and a .272 neck. What kind of velocities should this produce with 95 gr VLD's since I have about 4000 of them. I did order the 20 in barrel today. But the only reamer was a .273 neck.
Thanx

I think that a .273 neck is the best choice for a break-a-way as the rounds have to be hand feed. my .02
