I powder coat everything I cast. The powder coat doesn't totally eliminate the need for a gas check for really fast loads, but you can push bullets much faster with no leading than you could with just traditional lube. Plus there is considerably less smoke and lube fouling. I consider powder coating to be superior for 90% of cast bullet applications.
Also, I don't know if I mentioned previously, but the coating has its own hardness separate from the lead underneath. You can read some forums about this, but in my 1000s of cast bullets I've never done more than eyeball estimate my alloy, then once I powder coat the bullets I quench them in water. I've never dealt with lead fouling, at least not so much that a couple run-throughs of the bore snake can't take care of.
Are you casting, then powder coating, then sizing, then heat treating, and quenching after that? Or quenching after casting, then powder coating then sizing?
Yes I can believe that would make for a hard boolit,
What kind of velocities are you pushing,, and at what point does the need for a gas check come into play?
This opens up things beyond standard pistol subsonic uses.

Thanks for posting that. Those look great.![]()
Also, I mentioned it in the other thread, but Fortunecooki45LC and Elvis Ammo are two great youtube channels with lots about casting and coating
Those do look good and it’s probably cheaper than the hi tek coating.
