I need to specify a mold that will drop a .360 boolit with WW, but the manufacturer specs. his molds with Lyman No. 2. Lyman No. 2 would make a smaller boolit from the same mold, right?
What would be a good guess as to what size I need to order? Or to put it another way, if a mold drops a .360 boolit with WW, what size would you expect with Lyman #2? Best guess ...
Thanks.

About the same within .0005 " . Its hard to say because not all WWs are created equally.

Your mould maker should be able to tell you this. LBT, for example asks up front which alloy you use so he can get the bullet diameter correct the first time.
