New problems with my .410 brass shot shells. I reloaded and shot the brass shells a couple of times and all was well. After reloading a third time the shells are too tight to fit properly in the chamber of of my gun and the brass needs to be resized. I think Guesser was right when he suggested using .444 Marlin brass which I could resize with a Lee Loader kit and a hammer. Is there a die I can purchase to resize the Magtech .410 brass or can I modify/make a resize die? I need advice to solve this problem.
