Abrasive powder coat

[Big20]

I recently got into powder coating DEWC for my 38 spl. It didn’t take long to get satisfactory bullets. Target velocity loads proved accurate too. I noticed that the bore of my j-frame shined like never before. All traces of leading were gone. Anyone hear of powder coat being abrasive?

I have heard that some of the paints are but I was under the impression that it was a myth.

Any material has a coefficient of friction and will abrade things at over 1000fps. It's not sand paper but it's not wax either.

You should see how shiny the folding bars are on a facial tissue folding machine after running miles of tissue over them. And facial tissue is supposed to be soft on the nose.

I’ve also heard that one or two powders are more abrasive than most but I’ve slept a bit since then.

I cannot say I’ve seen any issues with the bores of my guns that I shoot powder coated bullets.

A good internet search should bring up some good info.

I've never seen or heard of any evidence that we should be worried about that. The commercial sellers of coated bullets will advertise that they will increase barrel life over jacketed bullets, but I take that with a grain of salt due to pistol barrels being almost immortal anyway. Only rarely do I talk to a person who has replaced a pistol barrel due to accuracy loss, and those are always USPSA Open Division shooters who hot rod 9mm caliber rounds and only shoot jacketed bullets.

I have not messed with coated bullets, and a question comes to my mind. Why would one want to coat with anything approaching abrasive? I would have thought coated would be somewhat synonymous with lubricity. I'm thinking Teflon or, what was the coating they used on the old Talon bullets, Lubalox?

I've very familiar with the term coefficient of friction. At times I've wished for either end of that ratio. Greased pig comes to mind. Or, an even smaller coefficient, goose-crap coated rocks in the rivers I wade. Cleats, my kingdom for a cleat!

I've seen the harbor freight black is or was, there was a guy that tested it and found it was. I tried looking for the article but no luck. Could have just been contaminated to, I worked there part time at nights when I was at ups a large amount of stuff was junk before it got to the stock room. Never fingered out why there was sand in the cardboard boxes, we're would have a 2" deep pile after a truck day.

Frankly, I sincerely doubt that any problems could ever arise from powder coated bullets. After all, it's not like any of the previous ideas for coating bullets ever caused any problems.

I’ve shot a lot of coated bullets through a P320, drop the FCU and barrel in the ultrasonic and everything is very clean. I don’t have the means to measure wear but everything looks clean. I’m not worried, if anything smoother is better.

Why would one want to coat with anything approaching abrasive?

Look up barrel lapping. Great idea for you custom PCers! Good luck.

From Hi-Performance Bullet Coatings;

Hi-Performance Bullet Coatings is bringing cast bullets into the 21st century. The Hi-Tek Heat Set Supercoat was developed specifically for commercial bullet casters to provide individuals that reload with a cast bullet that didn't smoke and gum up reloading dies like a traditional wax lubed bullet. Properly applied the coating molecularly bonds to the lead, encasing the entire projectile in a protective shell that is self-lubricating. This proprietary coating contains no PTFE or Moly.

FWIW I am using RAL 3028 Pure Red, SKU 215021 from Powder By the Pound.

Your talking tub dust... he also sells bullets already coated

Are any of the coatings acrylic? I've worn out airless sprayer tips in shot order using it.
