What's the general thought on .223 as a caliber for paper punching in a bolt action rifle? I'd like to have a nice bolt action centerfire that I can scope and practice marksmanship fundamentals. I pick .223 because it isn't as expensive as many of it's big brothers (.30-06; .308) and the local ranges will limit me to a few hundred yards at best anyway. Worst case scenario, is there any reason that XM193 can't be used in a bolt action? I stock that for my AR already.
