This is a question after I changed caliber from 40 to 9 open major. During the time that I was shooting 40 open, I always make sure that all reloads passed the gauge before using them. I am shooting 9 major at this time but never use a gauge for my reloads to check if they are ok. I shot around a thousand rounds but this gun just keep on going, no issue of a bulge brass or jam in the chamber. I have a KKM barrel on this gun and I use a Lee FCD on my Dillon 650. I want to know if this is a norm to most of 9 major barrel. I am using a once fired brass. Thanks.
