lead bullets coated with polymer paint

[plamenti]

...
Is the paint that hard that it squeezes the boolit down more than shave the paint off? Would be interested in seeing before/after pics of sizing.

Yes, that's probably so.

OK, but probably after three or four days - I'll work and will be out. Maybe I will make short video about sizing if you want, NP.

I really need t to try this.

How does that work then, you cast a .356 boolit, paint and then size down to smaller than cast? Is the paint that hard that it squeezes the boolit down more than shave the paint off? Would be interested in seeing before/after pics of sizing.

Ops, I have 2 pics but they are very poor quality:

Harbor Freight has powder-coat paint for about $5 per pound, in several colors. (red, yellow, black, white) I don't know if they sell a gun to apply it.

They do, I've been thinking of getting one. They sell some in kits, gun, paint, and tubing.

palmenti, that's a good set up. But I am to lazy to handle every bullet like that. I trie d coating them and hand tumbling in a box but they still stick to each other.

Would it make sense to size the boolits a few thou under before powder coating to reduce the amount of final sizing needed? Without getting carried away with custom dies, maybe sizing a 230 grain .45 down to .451 instead of .452 before coating would be a good idea. Just thinking out loud here -- just wondering about scraping paint off if sizing more than a couple of thousandths. Or am I worrying about nothing?

[leftiye]

Good question. I wonder if the paint would adhere well to a sized (slick) boolit. I also wonder if undersized boolits painted up to size would show problems holding the rifling.

The only problem I suppose with sizing first is that you will have to use some sort of lube and tha will have to be completely removed before the coating is applied or it won't stick. My mate who coats his bullets described the coating, but I never thought to ask him about the sizing.

I think unless you were going to get into it in a big way, it would be more trouble than it is worth.

Thats an interesting thought there too about having trouble holding the rifling. If plamenti is having success sizing a painted boolit down to a smaller than dropped size it doesnt seem like you would have to size before paint, just after.

Another question, are most painted boolits sold .355 like copper or are they sold larger like most people need out of boolits?

The only real downer about this whole thing may be the need to bake the powder coat. Harbor Freight has the gun for seventy-five bucks, but the oven is another thing entirely. Still, less smoke + higher velocity + no leading at all + no sticky bullets sounds like it is worth trying, even if I have to let somebody else have the fun of casting them. Then again, they do look like little lipstick cases...

Is my understanding for the heat required, most any toaster type oven will suffice.

[ScorpioMk]

Most people I know that do powdercoating at home find free/cheap ovens on craigslist.

[finishman2000]

i've even used my heat lamp (for paint) on powder coating. it worked.

[harley45]

This is interesting, we have a harbor freight just down the road, may have to check it out!

You need about 400 degs F. to powder coat/ bake or cure the powder..Very nice stuff. Try coating the base with a super thin coat of carnauba wax...One problem with wax coating is , conductivity is needed to adhere the powder.
Flaking or chipping with power coating is a sure sign of lack of cleaning before coating.

I just started into the kitchen to check heat range on the Wife's large toaster oven, but smelled pizza baking in it, so changed my mind. (;>)

[SlowSmokeN]

Ya I looked at the wife's oven and thought twice. I think I will look for a cheap one to keep on the side of the house.

Has anyone shot a couple hundred rounds through to see how it affected the barrel if sized like a lead boolit.

[Four Fingers of Death]

I have fired thousands of the commercial polymer coated bullets with zip problem. I don't know how you would go with the powder coated ones though.

That is what I would like to find out. How does the powder coat affect the barrel. Been watching this tread but it doesn't seem anyone has shot excessive rounds of powder coat.
