That's right, just another custom masterpiece from Tom's Miracle Machine Worx, "You dream 'em, I ream 'em", AKA Accurate Molds, LLC. Iron this time, probably all I'll buy from now on unless I need more than three cavities or are just experimenting and want the least expensive option. I could literally open the blocks and drop both bullets to stand on their noses. Cast 3/4 of a Lee 20-lb pot full and never once had to even shake the blocks to get the bullets to fall out from first warm-up pour to the last. The mould is a 45-297G, spec'd .452" with STRAIGHT clip-on wheel weight alloy. It casts bullets that measure .4521" and weigh 298 grains with my straight WW alloy @710°F. How's THAT for getting it right? Thank you, Tom.
