You'll get a lifetime of service from that snubbie. I lost count of all the standard pressure rounds I've put through my M85CH, but quite a few for sure.
I can say with relative confidence that it's seen well over 500 rounds of 125gr and 158gr +Ps. She's still as good as new.
The only trouble I've had is with cheap 158gr LRN ammunition. The bullets would back out of their cases during recoil and bind the action. Certainly can't blame the Taurus.
One of the best aspects of my M85 is how well it likes my favored carry load, the 158gr LSWCHP+P.
I believe the Taurus M85 continues to be one of the best values in the snubbie market today.
