I had a stainless Super B. for a couple of years. Regret having had to sell it to pay bills.
It was a wonderful point shooter. I could just swing it up more or less centered and drill the central body area of a human silhouette at combat ranges. Carefully aimed, it shot about as well as double-action S&W's, although the trigger pull was heavier. I used mainly Remington's now-discontinued yellow box medium (lead) load, and when I wanted magnum performance, I liked Remington and Federal 240 grain JHP and JSP ammo. I got excellent accuracy also from Remington's 275 grain game load.
I think I might use that one in big bear country or if I got carried away and wanted to shoot an elk with a handgun.
I really don't see much need for heavier bullets. I've read of cases where even 240 grain factory magnum bullets went clean through Alaskan brown bears, on shoulder shots! I think it's evident they'll penetrate enough for deer, and I really don't like to shoot larger game with a handgun, except defensively.
