You want some real fun? A 240gr LSWC/LRNFP over 3.5gr Titegroup in a .44 Russian case. A 'poof' load, it makes 692 fps from my 3" 696 and 714 fps from my 4" 629. It makes 'major' power factor from the 3" tube - and is really mild - anyone can shoot that load. Just remember to clean your chambers before loading the longer .44 Specials - and again in the 629 - when you want to launch Magnums.

BTW, you can get around the cleaning the chambers problem in a 29/629 by simply loading wimpy .44 Magnums - that's all I load - sorry, Elmer Keith!

PS To lessen the 'sting' of a RB 29 or 629, try the Hogue monogrips made for the .460/.500 Magnums - $36.78 from S&W Accessories and they fit K/L, N, X, and Z frames. They pad the backstrap - great recoil help.
