I looked the mold over carefully, and found no flaws so I scrubbed it thoroughly, and heat cycled it 4 times usinng my hot plate (solid plate), fired up my pot and filled the mold, I got a few wrinkled boolits and uped the pot temp until the just before the boolits frosted, and got really nice boolits. I let them cool for 2 days, and powder coated them let them cure for two more days, Then I sized them and and loaded 20 of them. The gun show is cleaning up today so I'll have to wait till tomorrow to try them out, but I'm sure they will perforate paper just fine.
