+1. The decapping die allows you to separate the: deprime, and, resizing steps. That is great for diagnosing the problem:I always suggest the LEE universal decapping die. For $30, you will keep your sizing dies much cleaner and decapping will go more quickly. I find that if I decap all my dirty brass, then tumble it, every stage of reloading is cleaner and faster, and my equipment stays clean.
