Shallow Denting after seating Federal primers
Quote from Reloader on August 1, 2021, 12:49 amthe primer pusher on my RL 550C leaves a shallow dents on small pistol federal primers. Usually I will have one or two maximum light strikes while shooting, but today, I was getting so many light strikes that I quit the USPSA match.
I usually clean the primer seating cup. After careful inspection, I noticed most primers were concave.
Did anyone experience this before? How to fix it?

A second possibility is to check your shell plate to ensure it is tightened. A loose shellplate can also result in high primers.
Lastly, and if you have the equipment capability, I'd change calibers and try priming some decapped cases requiring large primers. I'm going to presume the problem won't exist, and if so, I think it points back to adjusting your primer cup height on your small primer bar.best
