I've shot a couple of boxes of the S&B 158 JSP ammo, and it was okay, although what I shot was pretty dirty and awfully flashy. Personally, I have very little use for the 158 JSP loads, which don't usually expand well. That said, I won't stand in front of one, and it makes a pretty good round for deer and some other game. Expect overpenetration on human targets.

FWIW, much of the 125gr. .357 scare propaganda is just that. Enough use of full-house 125gr. screamers will cause some top strap flame cutting, but most folks will never shoot enough of it to cause any meaningful problems, and it tends to be self-limiting. I don't shoot them in my K-frame .357s, mostly because K-frame .357s aren't made anymore, and besides, they recoil enough in lightweight guns to make them unpleasant to my arthritic hands. (One cylinder-full from a 340PD was more than plenty.) I do shoot them in my 5" Model 27-5, and they don't make those anymore, either. I just don't shoot large quantities of them.
