Re: 6mm-284 vs 243 AI

I know 1 twist will not do it all. Coyboy sounds like you have the ultimate answer a gun/barrel with a twist for the varmint bullets and the long high bc bullets.

My plan is to shoot the 70-75 grain bullets at 3700 or preferably over, but while I am in the figureing stage I would like to know how heavy a bullet a 12 twist will stabalize? and a 10 and a 9.

I shoot a 6x284 with a 26" Hart BBL 10" twist. I can get 3,900 (70gr NBT)on a warm day with 56.3grs of H4350. 87gr V-max I can get almost 3,600 with 53.5 grs of H4350 and both loads shoot under 1/2 MOA at 100 yds. My hart 10"twist will not stabalize a 95gr VLD.

Re: 6mm-284 vs 243 AI

I can get +3600 w/ 87 v-max's out my ackley. It's an 8 twist, so I mainly shoot the 107's. Have played around w/ 80 gr BT's but they dont give me the consistency. You might think about a plain ole 10 twist and go w/ the v-max's. THose going almost 3700 are nearing 257 weatherby performance. I'm sure they would play hell on crows as well!

Shiredude why did you have to mention the 257 Weatherby ? I have a Rem 700 formerly 22-250 now 6x284 so I wonder if this means a short action? Any how I might like to have the next barrel chambered for 257 Weatherby? I wonder if my action will alow that?
