I can just see the robber now, “ you kidding me? You gonna shoot me with lipstick?”

Like the look of the coated bullets.

I like the powder coating as to it does in some cases saves on the lube process.

What is the 'sheet' underneath those projectiles mate & how do you get rid of the excess overspray?

Whatever you don't piss the Missus off mate.....they look bloody dangerous to me!

Your PC bullets look pretty spiffy mate, I'll have to look at this in the future for sure!

G'Day Fella's,

Down here in Australia (Oz), we have been shooting commercialy produced, PC bullets since the 1990's.
Apparently, we were the ones that came up with this concept.
I have used tens of thousands, of these commercialy produced PC (mainly Handgun but also .375" rifle) bullets, so I was sold on the concept, a long time ago.

I have only in the last couple of years, been coating my own home cast 0.375" and 0.423" bullets, but with complete satisfaction, and not a hint of any bore fouling/leading.
Initally, I was coating the bullets with dry powder (via tumbling method) but of late, I have started using the same powder coating powder, disolved in Acetone. Two coats and two bakes, are required to get a good bullet coverage.

I really do need to get a proper spay gun for this job!

D'oh!
Homer

Hey Homer if you get the chance can you put up your PC supplier please?
Is the alloy critical in regards to velocity and do you size after final coating?

The alloy will have to be (always) suitable for the pressure you are generating or there will be slumping of the bullet in the bore & loss of accuracy.
There is a formula for figuring out the needed brinel #, but I do not have it any more.

The mat underneath the cast powder coated bullets was one of those silicon grilling mats for the BBQ grill that I cut in half and then clipped the corners to keep them from turning up. I do the spraying on another tray that is covered with alum foil so it takes the overspray of powder and I have to clip the ground clip to a metal ground to get the gun sprayed powder to have a charged on the bullets. I then use a large hemostats to move them from the powder application tray to the bake tray. Also, it is as mentioned the alloy needs to be of the correct hardness for the velocity your planning to shoot them at, the coating is not going to protect the bullet from being driven faster than they should be just because they have a coating. Most times I apply any gas checks before coating due to many of my cast are shot as cast. They will be run through the lube a sizer just to apply the check.

G'Day Fella's,

The article I have, came from the SSAA rag, from the last year or two.
It's titled "Hi-Tek bullet coating of cast projectiles" by Geoff Smith.
The contact email for Mr Joe Ban of Hi-Tek, is; jandmspecializedproducts@gmail.com

Yes mate, I do size, and attach copper Gas Checks, after I have coated these Rifle bullets.

I mix 20 Grams of conventional Powder Coating powder, with 100 millilitres of Acetone, in a screw lid container. I then decant an amount of this blended liquid, into a Wide Mouth, screw lid jar, that already contains the bullets I want to coat.

D'oh!
Homer
