My Lee is going on 30 years of age. Just get the shell holder set which comes in a case you never have to worry about shell holders again. (15$)
I use it from 32 autos to 30-06 and have done some 300 Win mag with it.
I would have to guess, but it has to have primed well over 20,000 cases in 30 years. For the price it’s a very hard tool to beat.
