disassembled and cleaned mine multiple times, still fails... maybe it's just a defective assembly. lee will not send a new one to me for free. I don't feel like paying for another junk priming system.
The issue with the lee system is that it's too much of a gimmick and it has too many places where it can fail.
Then when it fails you end up with a press jammed in wasted powder and dummy rounds that you have to pull. No crap, I prefer to hand prime every cartridge by feel on a single stage, and be sure they are all primed fine.
I don't like the LM priming on the upstroke anyway, you can't feel it, and if you reload mixed brass, some primers are crushed a bit, and some are just not totally in. Reloading is a hobby that I like, and I am a bit OCD, so I hate it when I reload rounds with uneven primers....
I like to feel my primers and seat them all to perfection regardless of mixed brass.
One day I'll just get a dillon xl650 I guess, but until then, I tumble brass, then lube, then batch deprime and resize on the LM, then tumble, then individually prime (pain), then batch powder bullt crimp on the lm.
I just don't really shoot enough to justify a dillon press for now, and I don't have much spare money to waste for now so I keep my lm and it works.
