Not necessarily "the best OR preferred", but when I started with my 45-70s, I and the guys I shot with were, for the most part, shooting Elephant 2f. When that became unavailable, I switched to Goex CTG. Now that that is unavailable, I'm kinda starting from scratch, although I have been shooting Goex 1f outta my 45-90. Guess a guy has to roll with the punches . . .

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