Well a I finally got around to Leementing a some molds today. So far it I have done 4 sets and tested 3 of them, and what a difference it has made! The first mold was a C429-240 SWC, which I have owned for about 15 years. This mold was a problem child from the day I bought it. I had to furiously beat on the mold handles with my leather mallet just get the bullets to drop and when they did two of the bands were always rounded. Well today I got my carbide scribe out and worked on the middle band which had always rounded out when cast. Then I drilled a couple of bullets and put them on a headless screw coated them with paste made from Comet (per the instructions) and ran them on slow till the cavities were nice and clean. Then I boiled the molds for about an hour with some dishwasher detergent and water. Finally I put them in my Ultrasonic cleaner with clean water and ran them about 30 minutes. They came out looking new. The next molds were 2 different Ranch Dog molds which cast perfectly; but, don't drop bullets without beating on the hinge pin. I gave both of them same treatment as the first mold, with the exception of scribing the vents. I proceeded to cast with all 3 molds this afternoon and it was pure joy. All three molds dropped their bullets effortlessly and the C428-240 SWC had great mold fillout on the middle band. The top band, which I didn't clean out the vent lines, still had rounded edges, so this evening I will have rescribe all of the vent lines on that mold. This is a great thread, thanks for all the info!f
