New to this forum. Been casting for couple years now, and I tend to do larger batches, usually drop between 1000 and 2000 in sitting using Lee six cavity and Accurate five cavity molds. I push them through a Lee sizer, usually the lower side of whatever caliber. If it’s 45 ACP are usually do .451 and if it’s 44s I do .429. Then they get powder coated. And then back through the sizing die at the next size up. .452 for ACP’s and .430 for 44s. The second run through the sizing die is effortless. Probably don’t even need to do that step they tend to fall right through pretty easily. My problem is the first stage. I used to be able to trim these very nicely but the last couple batches I’m getting “tails” off the back of the boolits. Seems like the sizing dies are smearing the lead rather than trimming it. I’ve tried running copper wool and gun cleaner brushes through but nothing seems to help. I know Lee recommends using Alox before sizing but that would interfere with the powder coating. Pushed many batches through dry without this problem but lately I can’t get any size to go through. Using picked-up range lead as I always have, smelted down and later cast. A little softer than Lyman2. Never had a problem until lately. Any suggestions appreciated
