The problem:
I'm reloading 9mm on a Dillon SDB using mixed RPU brass. about 1 in 10 primers will not seat flush. Even off the press, with a hand tool, it won't go.
I've tried this is with 3 brands of primers and get the same result so now I'm looking at the brass.
And I do prep my brass: I clean, size and deprime, then de-crimp and clean pockets on a FA case prep ctr.

I want to add a primer pocket depth uniformer tool to the FA case prep center. So on to..

My Question:
Which brand? Amazon has a wide variety of tools from a wide variety of manufacturers made with anything from chinesium to unobtanium. What have you all used for "powered small pistol primer pocket uniform" tooling that worked, or, should be avoided?
 
Have you identified the brass that’s problematic and measured the depths of the primer pockets. 10% is a lot.
 
Multiple headstamps and brands are in the reject pile. I guess i otta disassemble them and measure... will report.
