John Barsness/Mule Deer has published some reduced loads with the old 220 grain Hornady FNSP and IMR 4227 that are very similar to 38-55 ballistics.
I've shot them and enjoyed.
Also - what the other folks have said about just using the starting loads and 235 or even 260 grain bullets... Not a bad call. I was pleasantly surprised by the fairly mellow recoil of a 375 H&H Ruger Number One some years ago. Have only taken a few black bear with mine, used the 260 gr Nosler Accubond at about 2650 fps. A starting load in Nosler's manual. Worked great.
