Keeping Aluminum Foil From Sticking To Bullet Base
A conductive coating could be applied to the aluminum foil before the bullets are set up.
A thin layer of carbon from an acetylene cutting torch with the oxygen turned off should make a conductive coating of carbon that the powder coating would not stick to the aluminum foil.
I too apply powder coat to pistol bullets with very good results.
The powder coat results in no lead in the barrel and the barrel is very clean after several hundred of fired rounds.
The next time I coat some bullets I will try coating the foil with carbon from a cutting torch.
I tried some case lube one time in a very thin layer on the foil but the lube sort of insulated the bullets and the powder coat did not stick very well.
Picture of bullets for 380 Auto, powder coared with cola can gas checks installed
Just an idea on how to keep the powder coating from sticking to the foil.
Re: Powder Coating Boolits
I have been powder coating bullets for 308 Winchester. I size to 308, powder coat, and then size to 309. initial sizing is performed with case lube as a lubricant through a Lee push through size die. then I use dish detergent and water to wash them, and rinse several times. then when they are completely dry, I powdercoat, bake, and then use a Lee push through sizer to size to 309 using no lubricant.
my alloy this far has been wheel weights with 2 percent tin. after shooting several dozen, my boar actually appears to be cleaner than when I started. so far the only downside I have seen is I have not been able to exceed 3 moa.
I recently cast some more bullets out of 50/50 wheel weights and Lino type. once I get them coated loaded and fired I will post my results.

Maybe I will give it a try....I wonder too if some colors work better than others and I suspect the ones with glitter would introduce an abrasive that wouldn't be good...interesting thread.
This was tried on another thread, it was impossible to get a uniform thickness of the powder coat.
I have tried powder by the pound's liquid to powder and an airbrush, also difficult to get a uniform coating.
