Well, that and he wasn't getting anywhere near 120 thousand spinamathingies, which is the minimum for stable flight dontchaknow.
My M29 dotes on .4315" bullets....HEYYYY that's the size of the cylinder throats, how about that?
Brad, I think that revolver wants to shoot, and you're getting good enough at the bench to make it shoot. The fact that you're already getting 5-6" groups with bullets mangled beyond recognition and leaded gas checks is pretty amazing, imagine how well it will shoot if the bullet was true and the bore condition stayed consistent?
