I just got a Lyman 535 gr. Postell mold for Christmas and was surprised ( and dissapointed ) when I weighed up several bullets cast with their Lyman #2 alloy and got a max of 519 grns of weight. I am using their old formula which calls for 55% wheel weights, 35% pure lead and 10% 50/50 solder. I then tried just plain old pure lead to see how heavy they would be and found the heaviest that I could get was 526 grns. What is going on here? I have used their 480 grn pointed bullet mould and with the #2 alloy got anywheres from 477 to 483. Am I doing something wrong or is this typical for this mold? Thanks, Jim W.
