Thread: Powder coating projectiles

Anyone on here powder coat their cast projectiles and if so where do you source the powder?

Cheers

I powder coat my cast bullets for my 6x45. I bought a bag of powder off eBay here but I'm sure you'll be able to get a bit off a local powder coating place.

I place the bullets in an empty ice cream tub with a small amount of powder and shake it to coat the bullets. I line a baking tray with aluminium foil, put the coated bullets in and then seal the the top of the tray with foil. 10 mins in the oven at max temperature works for me then I pour cold water over the bullets and separate the ones that have stuck together.

No more leading and a squeaky clean barrel after shooting PC bullets.

25 years ago my brother used to wrap his 45-70 cast projectiles in Teflon thread tape and spray them with aerosol clearkote. No gas check and was pushing them crazy fast for cast lead.

I bought half a pound of Eastwood Ford Dark Blue from Resto Supplies at a total cost of $32, and had to pay by Paypal. Resto Supplies have other colours but I chose the easiest application colour. Eastwood powder is the recommended TGIC polyester-type of powder (there is more than one kind of polyester powder) for easy shake and bake application. Dulux supply a polyester powder but it is the wrong kind, which means the price is high for the imported Eastwood powder. I have not found another supplier of polyester TGIC powder in New Zealand. The powder application is easy and the baking is simple. I follow the process outlined on the MP Molds website: https://www.mp-molds.com/tipstricks/...ble-dt-method/

For pistol bullets they are cleaner to shoot and reload,more consistent and more accurate.
Whats not to like!

Do any of you guys powder coating resize your projectiles afterwards?
Or is that a given?

As for why to do it I have had some given too me to try and they're clean as a whistle in the barrel and generally faster for a given powder charge over jacketed projectiles. Dunno if they're more accurate or not yet.

I dabbled with powder-coating in my XP100 30BR & 7mmBR plus my 357Mag revolver.

I needed to re-size ( Lee push through) after powder coasting or I couldn't chamber in the revolver as the powder coat fattened the bullets too much. There are companies like NOE who are making bullet molds slightly under-size to sell to the powder coat fraternity.

Certainly makes cast bullet shooting a lot less messy with no bullet lube/ lubesizers / etc.

Accuracy I can't comment as to whether it was better, but it wasn't worse and the bullets looked "sexy" .

In the early 80's I did exactly the same with my Marlin 47-70 and an RCBS cast projectile (ending up at 420gr) wrapped with teflon tape and polyurethane spray! A caseful of Rx7. Vicious recoil but accurate and zero leading. Happy days at the Waiuku Black powder Club.

Resto Supplies for powder, the Ford light blue and the Wagon red are the best i found for the shake and bake method. I size after coating. zero leading in my 9mms and 38s ,

the clearcoat looks like PERFECT camo coating @akaroa1

I prefer the clear coat too. It spreads thinner and copes better with multiple coats imo. Looks old timey as well

Im also using Eastwood powder from Resto Supplies. Im a fan of clear. I think its mostly because I cant see the tiny imperfections in the coating when its clear. Light blue works well, black is horrible.

A silicone heat mat is perfect for standing them on for cooking as the finished product falls right off and any excess paint does as well.

@R93…. Yeah mate,I’ve also had a chance to shoot a few rounds this way(308)…. Several of the members( gun club)swear by them.I sent your post to a mate of mine who reloads and into the powder coating to see what transpires…. Interested to find out for myself.

I shot a dozen rounds,but being a hack,really didn’t notice anything peculiar,they grouped similar to my factory stuff

@R93…. BTW…. Plenty of hockey on ,loving it…… GO KNIGHTS!!!

It seems , he powder coats for 2 reasons
(1) it’s certainly much cleaner
(2) it’s how he identifies his loads via different colours

He casts his own projectiles and reloads everything he shoots,hence the colour ID for different grain bullets….reckons accuracy doesn’t even come into it…

The 308/45-70 loads I get from him are all the same colour,…. Pkaying around with different loads….
