A new Lee 457-405 mold came in last week and yesterday morning I smelted another 20lb of soft plumber's lead and cast a handful to see how they would measure. They came out quite large, .460+. That is much bigger in diameter than the hot glue slugs I cast out of that mold last week to fool with. Those only came in at .456 at best.
Lead this soft isn't what I intend to use for these boolits but I am wondering if I use, say, Lyman #2 if these boolits will measure noticeably smaller in diameter? I have been fully ready to lap this mold to get it where I wanted it to be and am now thinking that may not be necessary. These lee slugs are not perfectly uniform, cavity to cavity, nor are they totally concentric around, yet the .459 sizer die appears to take care of that easy enough.
Should I leave well enough alone and find out what a higher BHN will yield?
