Loading for the 44-40
The current issue of 'Handloader' magazine has an article on loading for the 44-40, handgun, rifle and dual purpose loads.
Mike Venturino has also written on loading for the 44-40 in several articles and books, notably 'Shooting the lever Guns of the Old West'.
The powder recommended is Unique, but I have had excellent results in my Uberti Henry and '66 with 6 grs of Red Dot and a commercial (Bullet Barn) 200 gr. RNFP.
Two of my CAS associates shoot BP in their carbines and revolvers with great success. They do it for the history and nostalgia.
It is infinitely more so suited than rifle/carbines in 45 Colt. I've yet to see ejected 45 cases that weren't blackened and smudged due to a poor seal in the chamber. Some of these guys are also shooting very light bullets in the 45 as well.
By the way - 6 grs Red Dot is also a good powder in the 45 Colt, but lately I've switched over to Trail Boss which my 44-40s don't like ......
