I just came across this mold in 4 cavity. I was given some bullets by a fellow shooter to try from his 45266 mold many years ago. They shot incredibly well at 50 yards with 4.2 gr of Bullseye in my Clark Longslide from a Ransom Rest. Lyman only made this mold a couple of years, and unexpectedly dropped it. It took a while, but I did find one of these molds. It's actually a boattail bullet weighing around 215 grains. I haven't had a chance to cast with it yet, but I think it's going to be a winner.
Does anyone else have experience with this mold?
