I just picked one up on thursday. ran fifty rounds of .38 and .38 +p through it today. used pistol. no problems (although poa is about 2" low at 10-12 yards with the 158g .38 i was using.) Its heavy eboiugh i dont anticipate any problem with 357 in it, but dont shoot that in my backyard range. (nor larg rifle calibers, i dont want to annoyu my neighbors too much).
So far i am lovin it. Not sure what my grips will end up though. i put an old wooden set i have on it. love the feel and look, but it does tend to move. course that was wearing gloves.
so probably more than you wanted.. but my experience with it so far.
