I've been loading .44Mag Cowboy for/with a Buddy for 18years. Same Bullet weight; 240grs. Use the data from the Hodgdon "Cowboy Action Data" handout #5 dated 1/03.
With 240gr Bullet: N.O.E #432-240-RF;
Titegroup 4.7grs - 6.2grs , He uses 5.3grs, very consistent.
Clays 4.3grs - 6.2grs
HP38 5.5grs - 7.2grs (Same as W231)
Lee RN is a very fine Bullet, almost duplicates the ancient Lyman #429251.
If you do get to shoot some Rifle, PLEASE DON'T USE ROUND NOSE BULLETS IN A LEVER RIFLE.
Here are suggestions.
If you roll crimp over the front driving band on the Lee SWC it should be short enough to feed in any Lever Rifle w/o a problem. Regardless if it is old style or new TL style. Best to make up dummies to check cycling. If you're using a Win 16" Trapper, make up 10 dummies. If the loads OAL is short enough, you might get 9rds into the Magazine.
A lot of Cowboy Shoots call for 9rds. His Win Trapper WILL NOT feed even a long bullet loaded in a .44Spl case. We've only tried the Lyman #429667, and He doesn't like .44Spl loads.
Have found through Experience that Titegroup performs well under both Cold and Hot conditions.
Have add'l data for Hodgdon Universal & International powders too.
Long time Caster/Reloader, Getting back into it after almost 10yrs. Life Member NRA 40+yrs, Life S.A.S.S. #375. Does this mean a description of me as a fumble-fingered knuckle-draggin' baboon. I also drool in my sleep. I firmly believe that true happiness is a warm gun. Did I mention how much I HATE auto-correct on this blasted tablet.
