I want a bolt action rifle with hunting/killing performance midway between .223 and .308 cartridges, that is MOA accurate to 200 yards. What rifle or cartridge should I be looking for? Maybe .30-30? Or reduced charge .308 soft points? The problem I am trying to solve is finding a cartridge that will drop a coyote at 150 yards, DRT, without over penetrating. It may just be a matter of changing bullets. The .223/5.56 bullets just seem to zip through them, and they run off. The .308 bullets make huge holes on the exit. I have bolt action hunting rifles in both of these calibers, and I am not getting the terminal performance I want.
