It has been suggested to me that perhaps some of the troubles I am having shooting cast can are related to bore condition. With that in mind, I am looking at getting some surplus FMJ 147's or 152's to shoot a bit with from my 30-30. I figure that for punching holes in paper it really doesn't matter if the ball is FMJ or not, and the price is certaily right. You ever used any of these surplus balls? I can really so no reason not to use them. Thoughts? Thanks in advance, JP
