I load 9mm, but for a Sig. All I can say is that I ALWAYS finish my semi-auto loads with the LEE Factory crimp and I have yet to experience my first failure to feed ... somewhere between 1100 and 1500 rounds of .40 and 9mm. Where is the wood on my desk so I can knock on it fast
Bottom line is that it is 20 bucks well spent!
Good luck

Now that I read this ... I also load the bottlenecked 7.62x25 and I got failures regularly with those
