I was thinking 6mm 284 but I am a little concerned about the 1 in 8 twist at those velocities. Has anybody done this with this barrel and if so what were your results. I am planning on shooting the berger and sierra 95-105. If this is a problem please stop me before I go order the reamers and regret it. Thanks Stifle
a 1:8 twist will work just fine, but your also better off shooting bullets with a high B/C number. Not real sure how well the .284 case works with reduced loads, but sure somebody here would know.

I used to shoot a lot with some guys that were really into the 6/284, and they usually went thru a barrel a year! Then one of them reamed his chamber .100" short at the shoulder, and nearly doubled his barrel life. He lost less than 100fps in a 26" barrel (actually about 75fps). Then another guy did exactly the samething, but chambered it .150" short. It shot even better, and there was no real difference between the two short cases (still less than 100fps). But they were saving four or five hundred dollars a year in barrels. This kinda falls right back to some of P.O. Ackley's writtings; where he said that the 6mm remington case was about it for the .243 round. Myself; I'd build a 6mmAI, and never look back.

I hope the OP did not wait 3 years for the project, it would have driven me nuts if it was me.
