In order to save money on components for handloading ammo, many folks cast their own bullets. The problem with cast bullets especially once you start pushing them beyond 2000 feet per second is that you get leading in the barrel. The .223 caliber is going near 3000 fps out of a modern semi auto carbine so up to now the word has been no-go on cast bullets for them. So you are limited to buying jacketed or plated bullets which cost about 20 cents with every trigger squeeze. Add to that powder and primer (not counting case cost) and you are pushing the price of store bough ammo at 25 cents a round. So some folks have been experimenting with powder coating their own cast bullets in order to make their own "polymer plated" projectiles. Apparently in Europe you can buy them ready made like that. So the basic idea works. The fly in the ointment is how to roll your own consistently without a big powder coat gun setup. Some folks have been using the dry shake and bake method with varying degrees of success. Pop the projectiles in a plastic tub, add a couple of teaspoons of coating powder, cover and shake away. Pour them out on a tray and bake at 400 degrees F for twenty minutes. So I figured what the heck lets give it a try.
I re-tumble the soft lead round nose ones I originally coated in black along with some fresh hard cast SWC on the right in the pix and bake again. This time on parchment paper to prevent sticking to the aluminum foil.
