I have one of the ancient 32-165 Winchester molds (for 32-40 or .32 Special) in excellent condition. Essentially not used, varnish still on the handles. But the sprue plate doesn't sit flat. Looking at it I'd say it never has sat flat on top of the mold and that's why it hasn't been used. Sooo, I'd like to flatten that plate!
Anyone seen Winchester factory molds with this hickup before?
Got suggestions on the best way to go about fixing it?
The only thing I know to do is press it as flat as I can get it and then do the last bit of leveling by flat file followed with abrasives.
