Elmer Keith
I recommend a copy of his book "Sixguns"! It's out of date, as far as reloading goes, but the rest of the info is excellent! He did father the .44 Magnum. It came about as a result of his handloading the .44 special to velocities of 1200 fps. He preferred Smith and Wesson revolvers (and the Colt single action), usually in the 4 inch barrel. Mainly, for ease of carrying. Smith and Wesson made an "Elmer Keith" edition after he died. It consisted of a Model 29, .44 Mag., 4 inch barrel, with gold lettering on most of the gun. The first 100 had ivory grips. A total of 5000 were manufactured. They certainly had extra care put into them, because all that I've seen were slick as butter! I say his reloading data is out of date because of the changes in powder burning characteristics and the development of better jacketed bullets. If you'll adjust his max loads, then follow the rest of his advice, you'll soon realize how brilliant he was! His cast bullets, with a proper load of the right powder, will open your eyes! A hard-cast .44 bullet ( I use H&G's #503 mould) with 18 grains of 2400 (standard primer) will knock down ANYTHING! The same bullet with 7.5 grains of unique is an excellent self-defense load (around 900-950 fps). Use 5 grains of bullseye for a practice load (very mild) and you make the .44 mag into a very practical handgun! Except for the lower charge of 2400, all of these loads are in his book "Sixguns".
