My current 12 twist .223 can cause its fair share of dirt naps at 300 yards with my hand loads. It's also a fine paper puncher at twice that distance. I now find myself wanting to get into the 800+ dirt nap club and the aformentioned rig just aint gonna do it. I found a factory Savage model 12 in .22-250 with a 9 twist 26" barrel. This gun is in my price range and am hoping the .22-250 has the get up and go to let me ride the 75 grain amax all the way to the 800+ dirt nap club. Am I looking at this right or should I be looking at .243 instead?
