@ OP, like someone has already stated; take your loads and throw them into a J frame and get back to us. I'm afraid that an N frame like your 28 will tame down 357 Mag pretty decently, even with max power loads. If you want to up the ante in an N frame, go to a model 57 or model 29 or their stainless steel derivatives and shoot some 41 or 44 Mag rounds.

That is one thing I really like about 357 Mag, actually. It is a pretty darn potent round but is still eminently shootable in a large frame revolver or lever action carbine. Last time at the range I ran around 50 rounds through my 627 Pro and better than 100 rounds of hot 357 through my Rossi 92SRC and no pain.
