Having several different rifles they all seem to have their favorites. The 7mm08 Savage likes the hornady superformance 139 grain. The 35 remington shoots the 200 grain rem coreloct very well and the 45/75 likes the Hornady LE 325grain. But this year I am going to try and kill a deer with my hand cast and powdercoated 250 grain in the Marlin 375. When I still had 30-30 rifles I found each one had a different favorite round and at one time I had oiver 30 different boxes of 30-30 ammo. I say feed them what they like.
