I'm trying to develop some loads for my Rossi 92 rifle that is chambered in 45 colt with Alliant Power Pistol powder.
I'm pushing a 250 grain rnfp hardcast boolit.
There are some references to this powder as being excellent for 45 colt but there is little data.
The data there is ; is for basically low end loads ; where I am looking for safe loads in a rifle that can handle +p loads.
So if anyone has any loads they can share ; much appreciated
