I am new to reloading and have been buying 9mm brass through Gun Broker. I purchased 6,000 cases from 5 different suppliers. I mixed the brass together, then sorted and am now in the process of resizing and decaping. Everything was going fine until I happened upon Sellier & Bellot brass. On the first round, I broke the Lee decaping pin. After securing another pin and investigating, discovered the decaping pin would not even fit through the flash hole! Do I through away a few pounds of S&B brass or can the flash hole be safely modified to conform to other brands?
