I have 3 Lee 6 cavity molds (429-240-2r, 452-230-2r, and 358-158-swc). The second chamber (with #1 being the furthest from the handles) for all three is the stickiest. The rest of the chambers release the bullet upon opening (at least once I get to the right temp). Only the second chamber makes me reach for the wood mallet, and all it takes is a single firm rap to get the last bullet to release.
I very new to casting so before I get myself carried away with looking for burrs, polishing, etc, I thought I would check in. Since its the same chamber for all, I would believe that the problem is technique, but the sample size is small, so maybe it's a Lee issue (not saying defect, just maybe something with the design?)
All molds were washed to remove any manufacturing oils and then heat cycled before the first use. I use anti-seize as my sprue cutter, rotating part lube, but no lube has ever touched the casting chambers, Probably too much info, but I want to be sure before I start trying permanent, material removing fixes.
Is it me, is it time to read the polishing a mold threads, or is 1 rap how it is supposed to work?
