First Powder coats!

I am not saying they all are bad just that some of this stuff may not be good after 1000's of rounds. I have some PC on order and have already coated with four different epoxies I had on the shelf. If one is concerned about stuff going down the barrel there is always clear. I don't think any of the solid standard will be harmful, ie red, blue etc.

Was wondering where you are ordering your PC from?

I would also like to get started but not exactly sure what (TGIC/NonTGIC) to order or where from.

Thanks

Smoke4320 on Boolits. What is TGIC? Boolits seems to be the home of the acronym. If you can figure them all out you may be smart enough to be there!!

I buy my powder from powder365.ca and specify tgic free in the search.

I know some will say its not proven, but if i can just order tgic free then i will.
 
TGIC sounds like it could be nasty. Are we trading lead vapour/dust for something worse on an indoor range? Even if my stuff is okay what about the other guys and how do you know that they are TGIC free? You can bet lighting a fire behind this coating will liberate some into the air.
 
pish posh, your gonna get cancer from something so why not tgic :)

but since there is alot of tgic free powders on powder 365 i do what f55 does and just look through the powders that way. although if there is a colour i want (like kawasaki green) that has tgic i still use it. i bake the bullets in a old toaster oven that will never see food in it outside so i'm not worried about fumes.

All sounds good but with my Magma Star sizer I can size and lube faster than I can PC. I only need this for indoor where my club has banned lead. For outdoors it really does not matter to me lead or not. I am lucky to not have cancer by now with all the crap I have put my body through!

I started pc'ing bullets for leading in my barrel and a cleaner bullet. When i used alox i would get a lot of smoke, my 30-30 and 45-70 would lead. It could be the mix of my lead etc but pc was the easy way to get around the issues.

I did slug my barrel for example my 45-70 slugs just under 457 and i size to 459 but this ensures a clean bullet for me at least.
 
OK. I want to thank everyone for all the info and all the great pics provided on this subject. As I am just thinking about casting my own, because supply in my area almost always sucks ! I learnt a lot here, but I have a question that might seem dumb, but I honestly don't know, what is a #5 container and what real relevance does it make to the coating ability ?
 
Are thermo plastics or thermoset polymers used in bullet plating?
Thermoset polymers are perminantly cured. But the heat softening thermo plastics include low friction polymers like PTFE.
 
OK, tried some test batches, all the same bullets in three different color powders from Harbour Freight, as it was the cheapest I could find for testing. I used the tumble dry method and cooked at 400 for 20 minutes. The red coated perfectly with one coat, so I tried another coat and it again coated perfectly. I tried some black, and the first coat was somewhat spotty but the second coat cleared up everything. But wow, I tried a third batch in yellow and all I got was big clumps, it never covered ! I tried a second and third coat, but it kept on clumping. I even tried to slightly preheat the covered bullets a bit before another coating and again it clumped ??? Amazing differences from powder from the same source. For people that have tried better powder, different colors , have you had anything like this ?

I got the bug this spring.




I have switched to Hi-Tek coating from using powder. The process is so much faster and easier to do.

Here is a picture of 1500 bullets drying in the sun. Took less than 15 minutes to coat them with the first coat before baking.


And a basket fresh out of the oven




Hi-Rek powder runs about $100us per pound but will do about 22,000 bullets. Application is much faster and for the high volume user a lot faster from my experience and significantly less expensive.

It almost looks like there was a residue on the bullets that prevented the powder sticking to them. If you used the margarine tub application method I would be suspicious of there being a trace of oil in the corner of the tub.
