I cast up some Lyman 457193 bullets (WW'S) and they didn't shoot worth a darn. I've seen better shot gun patterns!! I was loading them at about 750 degrees with a hot mold. I miked them and they were dropping at 456 1/2 to 457. Pretty small and they were nowhere near round.

I had shot these in the past with good results????

ANSWER: I lowered my melt temp to 650 degrees and didn't let my mould get too hot.

RESULT: dropped to 459 and round.

RANGE: One bullet on top of the next.

By the way it was this forum and a lot of searching and reading that got me to think more about my melt temperature.

Thanks guys
