By far one of the very best things for me with Big Bore Texan is being able to make accurate affordable and custom cast slugs. I also powder coat too..for me very easy... cheap.....accurate...I would never be able to shoot if I didn't cast my own slugs... Its been very satisfying making my own slugs ...If anyone wants to learn to cast for.there Airgun ??????Or show off there homemade cast slugs.....If I can learn to make slugs I'm sure you can too....Here to to give support😀 Thanks Airgun Friends

I cast em and coat em too. I have molds that start at 17 grains and go up to 500 grains.

Seen something about powering coating slugs on another thread, but thought it was meant as a joke.

Does it really work? Possible benefits? How is the coating evenly applied?

Yes powder coating works. One absolutely huge benefit is never handling lead or lead exposure. I smoke I don't wanna wash my hands every time I handle a slug. It does reduce leading.... If your barrel is absolutely rough no powder coating won't fix horrible factory barrel.. I hand lapped my barrel and know with powder coat slugs and a touch of silicone oil I get good accuracy and no leading.... Also with shiny powder coating I see my rounds like tracers at night in my IR light and Sightmark Wraith😀👍 Federal ammo produced powder coated pistol ammo,,,,so legit......

The powder coating is applied using shake and bake method...coffee container,,, slugs,,,,powder coating,,,,, shake,,shake,,,dump off excess powder,,,,in the oven at 400 10 -20 min...Ottawa oven in water quench to separate..

I've cast and powder coated many thousands of pellets, slugs and boolits and I've never had any issues with deformation. 400 degrees is well below the melting point of lead. It will lower the bhn of some alloys temporarily, but the hardness will return as they season. If I am powder coating an alloy and I want maximum hardness, I water quench them as soon as I take them out of the powder coat oven.

Looks like that article is from 2018. Shake n bake powder coating has come a long way since then. Techniques and powder choices have improved and 2 coats are pretty much a thing of the past for great coverage. No one I know uses Harbor Freight powder coat anymore. Eastwood, Cardinal and other manufacturers have much better powders

@EdinGa I wouldn't know which is why I asked. I was trying to make sense of the deformation aspect. I guess the important thing to take away from the article is to be mindful not to place trays too close to the heating element. Even still, if the oven is set to around 400F and left to bake for around 15 minutes, I'm unsure how parts of the tray would approach 620F. So I figured I'd ask if anyone exprienced this.

This article appears to be more current. https://americanhandgunner.com/our-experts/think-tank/why-powder-coat/

I keep my tray on the lowest level so that I get more even heating. That said, none of the cheap ovens I've used ever make it to 400 degrees according to my infrared thermometer. 385 is as high as I've seen, but it still works great with the powders I use.

The best results I've ever obtained come from polyester tgic powder coat. I prefer Eastwood and Cardinal brands. It is important to make sure you're buying a polyester tgic powder when ordering though.
