I've tried several things to keep my bullets from sticking to whatever it is I cure them on in the oven, (wire mesh, galvanized nails, silicone spray) but nothing has worked until now. Dytech Oven Liner (I found it at Menards on sale for <$3). I put the bullets on it, baked them, and they slid off like they were greasy marbles. Even the extra PC blotches came off! I had originally planned to get a silicone baking sheet, but this was less expensive. It says it's re-usable, and I've done 3 batches now and it doesn't seem any worse for wear. Try it, you'll like it!!
