jorgeI - I have a Marlin 1895 Cowboy in 45-70 approx 2003 vintage. I use 54 gr IMR 4350 under 40:1 cast Lyman 457193 (RNFP) lubed with 1:1 beeswax/mineral oil mix and a card wad. I crimp enough to keep the bullet from falling out or going farther into the case when loading the tube.

Someday I hope to be the person my dogs think I am . . .
The only true cost of having a dog is its death.
