I think I have most of what I need. I have:
20 lb Lee bottom pour pot
RCBS mould #45-255-SWC, 2 cavity mould for 0.454 with handles
20 lbs lead from RMR that list a hardness of 10
Safety equipment to include welding gloves, eye protection and a well ventilated area to work.

The revolver is a Ruger Blackhawk (1977) that has oversized throats. Normal 45 colt size bullets slide right through the cylinder. I did slug the barrel and it is the normal dimensions.

I have been loading and shooting lead bullets from Montana Bullets, and others, but want to give this casting a try.

The lead is in the form of rejected bullet cores and thin wire sections. I have been reading an online book by Glen Frywell and Robert Applegate, but that is almost information overload.

I am guess that I should start with casting ingots, and a mould for that is the one thing I don't have at the moment.

I am hoping someone here can point in the direction I should be going.
