powder coated cast lead?
I've never bought them but I've made them. Do you cast? The powder coating isn't hard. I put a little powder in with the bullets and some acetone in a plastic jar. Slosh it around until they're evenly coated then put them on a tray in a toaster. start with a low temp (100F) to get the solvent evaporated away, then crank it up. If I skipped the slow start with the temp sometimes they catch on fire. So its an outside activity.
I do the dry method
shake the bullets in a type 5 food container with the matte black air soft BBs and harbor freight red powder coating , then with a nitrile glove on dip the fingers in the powder then pick bullets out and set them on the baking tray on parchment on their base
I have a little convection oven I set to 400 and cook 10 minutes
it is all about if you have time , sometimes it is just wanting to get ammo loaded for a match or something so buy a case of coated from the store.
