I tried using the load data from Sierra and loaded up 135gr Nosler JHP over 11.5grof Unique (compressed load, 11.7gr not sure how they fit that)and shot 100 of them today. Very much akin to a good 357 Magnum. Stiff and pretty dang accurate.

I have not reloads them yet but they have been resized, decapped, and wet tumbled n dried. Nothing unusual to report so far.

Firearm however may be an ideal choice for stuff rounds. It is a 4" S&W 610. Brass used was new Starline. Not much chance for a smile and extraction was uneventful.
