Brunen, the 147gr. +P+ Hydra-Shoks were actually developed for use in .357 revolvers, for "political" purposes for agency use. It is great ammo, but it is a bit hot for your Model 10, at least on any regular basis. Pressures with that round peak briefly at low-end .357 levels. I've shot it in K-frame .38s, but mostly I treat it like the "-P" .357 loads like Remington Golden Saber 125gr. and Speer Short Barrel 135gr. .357 loads and only use it in lightweight .357 revolvers. It won't blow your gun up, but it will beat it up over time, with enough rounds fired.
