aalf,
While I have nothing but respect for your experience, why go as slow pass possible, or refine twist down to 1/4", for a HUNTING rifle? Especially when there is no downside to a 1-10" for the OP's purposes?
Right now I'm working on a article an article on "over-engineering" for a well-known periodical that basically specializes in hunting rifles. I'm going to discuss a lot of things, including triggers, magazines and safeties, but am now going to add rifling twist to the list, because this thread is a perfect example.
