I've done as Groo does, with Trail Boss - a lot of fun to shoot. I just loaded some up for a friend who has a Model 58. I favor a load that I based on Jessie's load, though: I use 7.5 grains of 7625 under a 215-grainer for 1015 fps out of a 4" tube with single-digit deviations. It's super-accurate for me (never found anything out of a .41 that wasn't decently accurate, tho the Trail Boss loading referenced just now wasn't especially so) and easy to shoot - but still would deliver the mail to an evil-doer.
