I shoot more than a few Coyotes, Bobcats, Pigs, with a .243 A.I.1x8 twist and a standard .243 1x10 twist, the problem is are you saving hides? if you are bullets make a big differents, if your not trying to save hides bullets make no differents, shoot what ever you can find that you rifle will shoot, you will learn to like the bullet.
