Effects of powdercoat on bullet hardness

[AJC1]

Powder coat is going to be a much harder coating on the bullet.

Hi-Tech is quicker...for me. A couple of minutes to swirl...at the most and two bake cycles.

I coat while I'm casting or loading. It doesn't take that much time. I never had any success with just dumping powder coated bullets and baking them. I've always had to stand them up and that's a big time sink.

So far I have taken the time to stand up each bullet on their base. My first batch I banged the tray and most fell over.... I wanted to scream as it was 200 and I had to do it over. I see people using the basket method I have a basket but not thrilled with all the results I see.

The powder coated bullets I was given to try left green dust, flakes and smears everywhere. When I picked some flattened bullets up from in front of the steel the coating was intact. I concluded they were done properly but it was not for me.

Now I just need someone to do Hi-Tek coating in John Deere green.

Leading can be caused by the bore/bullet diameter size as much as the soft lead, but coated lead eliminates almost any chance. I've run them up to close to 1800 fps out of a 8 3/8" revolver with no hint of leading as well as out of a lever action a little over 2000fps. Funny, the lever action did have a little coloring of the coating in the barrel, but no leading and the color cleaned right out with a dry mop

Same results here. I never want to go back if I can help it.

There shouldn't be dust, flakes and smears if the coating is properly cured. Many people starting in powder coat don't bake long enough. They get confused because the coating might say 9 minutes at 385°, that 385° is PART temperature, not oven temperature.

There are two available greens in Hi-Tek. Zombie green, no flakes and Kryptonite, darker green with gold flakes.

I'd guess the next color to come out will either be a pink or a purple. Both are being tested down under.

Gold for the honeys, and green for the monies.
Kryptonite.

MBCs are Hornady and Savage red, though.
This I’ll leave to the professionals. Perhaps later when my time is less a commodity.


Something for @ACJ1 to consider...


There are things that can be added to lead other than tin. A different chart shows wheel weights having arsenic in them. Some show zinc.

Oops off to work!

i see your lead hardness table and raise a copper alloy jacket hardness table: https://books.google.com/books?id=G...AQ#v=onepage&q=bullet jacket hardness&f=false
