I also picked up som Federal NT 40's at the range, one of our local FD members was shooting them. I was impressed on how clean the brass was, just like new. I deprimmed and reloaded. Primers fit with no problem.
One answer that puzzled me is , how could moving to small pistol primers be a step in the right direction. Large or small primers still make the powder ignite. If we go to small primers then we might have to adjust our powders, but maybe I am wrong. Of course the last part refers to 45's.
