A day or two ago my new Lee .452-200SWC mold showed up. Yesterday I prepped the mold i.e. got the sharp edges off the sprue plate, surfaced the underside of sprue plate and cleaned the blocks with solvent and Dawn.
Once the mold was prepped I warmed up the pot so I could see what the new boolits were gonna look like and everything went just about as planned. I dropped a couple hundred of these and other than looking at the boolits after opening the mold I never gave 'em much thought, they looked good. The only difference was that I was water dropping because I wanted to lube them later and possibly load them today so I couldn't really see the whole boolit as they were in the bottom of the bucket.
When I went to pull them out of the bucket I first noticed what I though was "finning" on the boolits where the blocks meet. Upon closer inspection with my bifocals it became apparent that it wasn't finning but mis-aligned mold blocks. To the naked eye while casting and looking down on the blocks from above they appear to line up perfectly. After discovering the problem and inspecting the block which still had boolits in them they appear also to line up 360°.
Anybody ever have this particular issue with a Lee mold before?
