I've been fighting with an RCBS 45-250 KT mould, and now have modified my technique and am having some success. Alloy is 1:5 Lino-WW @ 700ºF. Problem was fillout/frosting of the base band—which was never a problem when I cast for .357, .44, or .45 ACP.
I was extremely critical when I inspected the boolets, and have a pile of keepers with sharp bases and a pile with a slight (barely detectable) rounding of the base...everything else went back in the pot. I weighed samples from both piles, and the ones with the slightly rounded bases weigh about 1.5 gr. less than the sharp ones.
I've never weighed peestol boolets before, just given a visual inspection. So my question is: how much variation is OK? 1.5 gr. difference from a 250-gr. is barely over half a percent.
