in the FAQ'S, sharpshooter listed the 8 twt is able to stabilize up to 80gr bullets. i would think that the 9 twist would stabilize a 75gr bullet. the exception to that would be maybe the bergers since they have a long nose and or barnes since it takes more copper to make up lead weight and that results in a super long shank end of the bullet. (im not even sure if they make a 75 gr barnes....lol)

hopefully someone chimes in w first hand experience.

in my 22-250ai, i only plan to shoot 60gr at the heaviest for deer sized game. most of my ammo w be of the 50gr variety (vmax and 52gr amax) and am considering the 50gr barnes for deer.
