I've used Lil' Gun max 158- and 180-grain loads in .357 in my revolvers and my carbine. It's pretty remarkable from the carbine, but nothing special from the 3" and 4" revolvers. I never noticed the heat, either, in any of my .357 or the one .41 revolver I used it in. Frankly, given the experience level of some of the people warning against such use, I now try not to use it in my revolvers. But I'm not crazy paranoid about it - if I were in the field and that's what I had, that's what I'd use.

But, from a short barrel, I've found I can do just as well (sometimes with more minimal spreads) with "traditional" magnum revolver powders. So I've decided, "Why take the chance?" It may be that you come to the same conclusion.
