Got the .44's shooting now what?

[Kurt]

I'm sitting here looking out the window watching the 25 mph winds blowing the snow around in the bright sunlight with a Bald Eagle hovering about 200 ft above the ground looking at something on the ground. It amazes me how they can hold in a wind without moving holding in one spot with a 25 mph head wind for just about one minute.

I'm going to pull out as soon as Carol heals up to spend time in Cactus land and do some shooting and I thought that maybe I should use the .45-70 that I seldom use.
I know this rifle shoots well every time my Daughter shoots it but the loads were all loaded with the 2&3 f goex exp powder so I don't have time working up a load for it, besides it just aint any fun shooting in the cold with blowing snow in the lower teens.
I want to start shooting the silhouette matches because a few are starting to get started close to me and I think the .45-70 will be a good one for this because it was build for this game.

Where do I start for a load????
