25 years of use and still shooting like a razor.
I was one of the very first to buy one in holland.
To be honest, I only use mild to moderate handloads. It is absolutely fabulous on the shells. The first (federal) shells started to give after at least 50 times reloading. The only thing I disliked from the begining were it's grips. to small for my big paws. (normal square frame, not like yours)
I allready owned a Sauer & sohn DA .22lr/.22magnum (copy of S&W .22 masterpiece K frame) with the perfect grips. Got an extra set, put it on the S&W, fits like a glove, shoots like hell.
I also must admit to some serious gun abuse.
Last time I cleaned it must be at least years ago, I am still waiting for the first misfire. I only use self cast RCBS SWC's although Lee's SWC were better, until the mould died on me.
Good choice, never get rid of it, it will last you a lifetime probably even without proper care.
