G'Day Fella's,

Mr Nosler, please accept my apologies for posting this but some tinkerers may find it of interest!

FYI, here is a thread I posted on another great forum www.NitroExpress.com

G'Day Fella's,

Just a bit of a follow up on this.
Here are some images of some .375", 280 grain hard cast bullets I made and then Powder Coated to other day!
FYI, these were Tumble Coated and the out come, was only OK. I'll order a purpose made spray gun for it shortly!

Here is what happens, it the temperature adjustment dial on the oven, is out by 40+*Celsius!

And how tough this coating is, once it is bakes on and cured!

Interesting Homer. I know nothing of powder coating but have to wonder what the heat does to the hardness of the bullet.

I coat my cast bullets with HI-TEK coating. Foe me it seems a lot easier and less of a mess.

now i'm curious... what is the reason/advantage of coating the cast bullets?

Higher velocity with out leading.

G'Day Fella's,

Truck Driver, I'm not sure?
So far, after baking, I let the bullets cool down outside in the air. Some quench =them in cold water!

Steve4102, nice looking bullets they mate, most impressive!!!

Tim629, it is like adding a synthetic jacket to your home cast lead bullets.
The thing I want to try, is to cast up some very soft alloy bullets, then Powder Coat them, the test fire them (at Sub-Sonic velocities) into drums of water, to see if the bullets expand/mushroom?
As Truck Driver says, you can cast the bullets to be very soft but then run them at high velocities, without any leading!

Doh!
