Mine is coming to it's end of useful life. Several hundred thousands of rounds loaded, which means over a million cycles?, it now needs constant cleaning/lubrication of the ram as it starts sticking after a couple hundred cycles. I'm considering milling some flats on the ram to reduce the friction. And yes, I've taken it apart, cleaned the ram and douched the housing. Carbon and primer residue are the likely suspects although I may have bought a lemon these 40 years ago.
