Hey guys I have a question on .357 Magnum ammo. I recently just got an S&W 686 and a Model 19, my model 19 is to be my "shooter". I read a couple of articles online about the model 19s barrels occasionally cracking when hot magnum rounds are used. Has anyone here had any experience with this happening? I have a stash of Fiocchi 142 grain FMJTC @1400 fps, and I was wondering if these would be too hot for my K-frame. My Model 19 has actually quickly become one of my favorites and I don't want to do anything to shorten her life. I would really appreciate any input you guys would have on this topic, thanks for your time, Jon S.
