I have a S&W 60-15!
It's a great gun. (There's no problem with 180-grainers or even 200-grainers in the cylinder.)
I carry Federal's 130-gr Personal Defense Hydra-Shok .357 load, which is reasonably quick out of a shorter barrel. For hiking, I carry Buffalo Bore's .357 158-gr JHC, which they say (and folks online concur) gives 1398 fps out of the 60-15's 3" tube.
Surprisingly, recoil isn't horrifying. The oversized "crescent-moon" grips really work for me. Plus, I used to own a 21-ounce Taurus .41 magnum, so . . . it's all relative.
I don't shoot the 60-15 a lot, but I'm impressed with all the slick little touches on it. The trigger face is smooth, and the trigger pull is smoother. The metalwork is outstanding. The sights are wonderful (once again, thank you TERRY MURBACH for lighting a fire under S&W to make 3" adjustable-sighted J-frames), and the gun points perfectly.
Anyway, you'll do well with the 60-15, if that's what you wind up with.
