Today was my first time, and I think it went well! I used my new Lyman 452424 mould. I started with the temp around 700-725 but the bullets were wrinkly. So I turned it up to about 775 and that seemed to do the trick. I cleaned the mould with brake cleaner, then Dawn detergent with a toothbrush and hot water, then brake cleaner again. I think the first 50 bullets were bad, with wrinkles and other deformities. So I put them back in the pot. I can see how a hot plate would be a good idea to keep the mould hot. So here are some pics, and tell me what you think. Maybe the melt wasn't quite as clean as it should have been? But it seems like they filled out correctly, I hope? I used WW and 2% Tin. Does it look like I cut the sprues too soon, or too late?
