I was wondering if I could get some input on a 20PPC. I'm wanting to do something a little different to shoot groundhogs with and the 20PPC interests me. I'll be looking to shoot the 32-40 grainers and want to know what twist is optimal for those bullets. Also I'm not familiar with the neck diameter of .20 cal bullets for a chamber. I'd like to atleast skim some off the necks and want to know what neck the reamer should be. Also I have a PPC die that I intend to use - I'll just swap out the bushing. Would that work?
