Good bullet for Colts, inexpensive mould and easy to cast with. So easy to cast with I can run the 6 holer with a ladel and still have very good boolits. It will do ok for black powder from a revolver but runs out of lube in the rifle in my experience. For 9# of pure lead, I'd suggest at least 1 1# roll of 50/50 soulder if for no other reason than the better fill of the cavities, it will increase the hardness of the bullet a bit and help eliminate any leading problems.
