I felt like I had everything dialed in pretty well. I'm using Lee 9mm dies, range brass, SNS coated bullets and a couple of different powders. I'm checking my powder charges and OAL every so often and they look to be consistent.
Everything has gone bang, and the accuracy level seems good. But I'm having other issues, like rounds not quite going into battery, failures to eject, stovepipes, etc.
I'm just not sure where to look for the problem.
