I have had the decapping rod slip in the collet on LEE dies, and I will never again use a sizing die that does not have a threaded decapping rod.
I have mostly Lee carbide pistol dies and have no problems with them . Also use RCBS . I like the collet on the Lee decapping rod . I have never broken a decapping pin with my Lee dies . Wish I could say the same about my RCBS dies .
They are supposed to slip. That way they don't break!
The pin will break if, as in my case, you are loading a couple of thousand 9mm or .223 and end up with the odd military round mixed in. Unfortunately these don't always pop out and will occaisionally break a pin....unless you are using a Lee die in which case you simply reset the pin and a way you go
I don't bother with cases that have crimped primers, so it isn't an issue.
lee dies are not to bad............but the presses are cheap cast aluminum crap
I have never broken a decapping pin in over 30 years of reloading. Unless the decapping pin is out of alignment, you won't break a decapping pin. And if a person can't figure out how to adjust the decapping rod, so it doesn't bottom in the case, perhaps that person should not be reloading.
Try ramming your threaded decapper though several berdan cases accidentally mixed in with 1000 5.56 cases that were supposed to be all boxer
So you need a weak design to protect you from your own inattentiveness?
