Just got a new mould from Track of the Wolf, got a couple in fact. The .380 one drops rite at .380-.381, the .454 drops a .450-.451. .451 is a might too small for the cap and ball colts I had intended to use them in.
I'm using pure lead, and if I remember rite it shrinks a bit more than alloyed lead? Or do I need to get the mould hotter? The only other thing I can think of is too cast the balls and do the cutting compound trick of spinning the ball in place to open it up slightly. I've done this before with success for bullet moulds, would the ball still be pretty much round after doing it?
Thanks, I hate casting 2 balls at a time, don't mind it for the flint lock, but cap and ball revolvers can eat a lot of lead quickly.
