I've been getting back into casting, and while reading some of the back threads, I ran across this one about the differences between the Ideal 356402 and the Lyman 356402 mold designs.

So, naturally I had to dig out my old(40 years old) Lyman 356402 4 cavity mold and compare my bullets to those shown in the thread. Mine look just like the pics of the Lyman 356402.
However, mine are coming out of the mold considerably heavier, at about 132 gr, and larger in diameter, .360". I have weighed and measured about 8 bullets, so I think I am pretty close.
Are my bullets oversized due to the mold, or my alloy? Quite frankly I have no idea what my composition is, though I can usually gouge it with a thumbnail.
