I inherited some Lee boolit moulds from my Dad and have now managed to actually cast my very first boolits. The mould is a 9mm 125gr. .356 (Lee 90309, 356-125-2R) which I cast using an unknown alloy, probably with a fair amount of linotype (or maybe monotype). I also inherited a Lyman 450 sizer/luber with a .356 die and 311 top punch. When I tried to size and lube these boolits, it was really hard to force them through the sizing die and the top punch left some prominent indentations on the boolit. My questions: am I using the right top punch for this mould? Is there a more appropriate top punch for this mould? Should I have to lube with LLA before sizing? Wrong alloy? Or what? Any advice greatly appreciated from all you experts!
