I've been trying to wear out my old Security Six .357 mag with a steady diet of max loads of WW-296 & 180gr LBT cast bullets for years! I've owned it for at least 35 years now. It hasn't loosed up any, as far as I can tell.
Look someone else mentioned, it's probably one of the stoutest mid sized .357 Revolvers ever built. I sure as heck wouldn't worry about wearing it out. Just shoot it and have fun.
