Meaning to buy non-stick tin foil, I mistakenly bought non-stick parchment paper. Oh-bugger! Wait a second, it's tested to 425 degrees F. Ok, I gave it a try. It worked beautifully! my coated bullets didn't even try to stick to it. I was careful to set my toaster oven to 400 and timed it to go no more than 10 minutes. The paper turned brown and I'll only use a sheet once and always do it in a fire-safe area. I don't have a thermometer to test my oven, all I know is the 400 degree setting does the job, so it must be close. Also the bullet bases are coated as well.
