Default Coatings for cast lead bullets

Ok I have been doing some research about coatings for cast lead bullets, I want to be able to cast for some calibers that cast bullets may not work well. Specifically 300 BLK but also my auto loading pistols.

I don't want to go traditional powder coating. Too much equipment to buy. So I have been checking out the epoxy paint route.

So I have heard that the shake and bake process works pretty good. I could see trying it out but don't know if there is anything specific to look for as far as paint or technique. Paint and thinner in a bucket shaken like applying the alox. Dumped onto a metal screen and either re-coated or baked.

I was thinking if they are flat nosed to stand them on the nose and spray the bottom and sides. Then bake the paint on. As long as the sections of the bullet that contact the barrel are coated then I should be good to go. Similar to a jacketed soft point.

If anyone has any thoughts or input on coating cast bullets I would love to hear about it.

I'm assuming that you are wanting to coat them to reduce/eliminate lead fouling.

Any coating that you apply will have to be flexible enough to stay put on the bullet while it is getting squeezed down the barrel, up to 0.004" of compression for a 30 caliber round.

It would also have to resist the temperature of the burning powder and the friction between the bullet and the barrel.

All of your suggestions cover one or two of the issues, but not all of them.

The cheapest and easiest coating would be electroplating the bullets with copper. All you need is a tank, a wire basket to hold the copper, a wire basket to hold the bullets, a conductive liquid (vinegar), and a low voltage power supply - a 6 volt battery or a 6 volt low amperage battery charger.

Copper plate, size, gas check, and lube.

I just casted and powder coated a couple hundred boolits yesterday.

all you need is,

#1 a toaster oven. I got mine at Walmart for $20 but you can find them at goodwill for less.

#2 powder coating powder. a lot of folks use Harbor freight red cause it's cheap and works really well compared to other harbor freight colors. I ended up buying a pound of John deere green and a pound of dark blue from a guy on the cast boolits forum. I think it was $20 a pound and one pound will coat like 7000 boolits.

#3 a case tumbler or a cool whip bowl with airsoft bbs. I use a lyman case tumbler for mine. I just fill it with boolits, add a spoonful of powder coat and let it run for 20 minutes. dump the boolits in a colander and sift out the unused powder and save it for further coatings.

after that just put the boolits on a baking sheet covered in non stick foil and bake for 20 minutes at 400 degrees. size the boolits, load and shoot.


it's not hard and you can get into it for less than $50.

I thought I replied the other day but looks like it didn't post.

Thanks AGAIN ! You always have the right insight and help for my questions!

I will check out the powder from Harbor Freight. if you could post a little more detail I would appreciate it. Like how you transfer the costed bullets without messing up the coating, and how long and what temp you cook at.

Being able to easily coat cast bullets so that I won't have lead building up in the gas port of my AR would be very helpful! Then also loading magnum ammo with no gas checks or barrel leadding and smooth feeding from auto loaders is going to be great!

Interesting.... the Airsoft BBs generate enough static to get the powder coating to stick?
