RBH and Universal. I think its full name is Universal Clays.
I got my old 4-5/8th Black Hawk back with new, better cylinders and looking at my powder choices, I have the most Universal to make a good load with. I don't really have a feel for this powder and how it will do in the big case. Is it worth my time or should I try a classic powder like Herco, which I have very little of???
I have an old Ideal 452423 Mold, and though a little beat up and rusted in the nose before I got it, overall it makes usable bullets.
Here is its bio:
"452423 Newly designed 45 auto rim bullet by Elmer Keith. Band and lubricating grooves designed to give best results in Model 1917 revolvers, when reloading auto pistol or auto rim cases. Recommended charge is 4.5 grains of Bullseye. (PB, 240 - TP is 424)".
Mine casts 245 grs in my scrap alloy.
I am not looking for Ruger only loads but a good, accurate, stiff Colt load is fine.
