I know most of the regulars are not crazy about the Lee LoadMaster, but I have had some very good success with mine and since I got it used for $150 with all kinds of extras, I like it even more. It's not without problems and I think one of the most common complaints is the priming system. I wasn't having any problems for a while but recently when I switched over to load some 40, I found that my primers weren't seating deep enough. I made a simple adjustment to the depth using the adjustment screw and went along thinking everything was fine. It wasn't until I switched back to 9mm that I really started having problems. I started tipping primers and chewing up primer sliders like crazy. I was really frustrating. I cleaned everything, deburred, replaced, etc. Still it would happen. After a little research online I found the solution. It's explained really well here. http://www.42gpw.com/reloadingbench/loadmaster_setup.htm If you're having problems with broken primer sliders and tipped primers, check this out. After double checking the die setup and primer adjustment screw, everything has been flawless.
