[QUOTE="highdrum, post: 1780848, member: 13732"] If you're going to really stretch it out with heavy bullets(225-230gr) 1:9 will do you well. 1:8 twist is something Hornady has pushed with the 300 prc, which I believe will lean on their heavy(230-250gr) atip bullets. I bought an 8 twist bartlein rem varmint contour barrel planning on going that route, however I went 1:9 on the build. I shoot 300 norma improved which equals rum velocities. If you want to shoot 230s to 1000y go 1:9, if 215s is your game 1:10 will do the trick. Some bullets will blow up due from too much twist and velocity, so select your twist and fodder wisely.
