FN in MTPowder coating cast bullets?
Anyone powder coating using the Hi-Tek brand pc?
What solvent do you use?
Its as easy as coat twice, then run through the sizer?
Any recommendations appreciated.
Intending to do 9mmand 10mm auto.

92fstechI am powdercoating with Harbor Freight powder (the white kind, because that is what they had when I went in there to buy it). I stick it and the bullets in an old sour cream tub dry and shake it around, then dump it all out onto the wire basket over a piece of cardboard, pop the basket of bullets into the oven and pour the powder back into the sour cream tub. Bullets come out of the oven, into a bucket of water to cool, then dry them off and repeat for a second coat. After that, they go through the sizer.
Im pretty new at this...have only done a couple of batches...but the results have been satisfactory.

45 CalI use H F brand,red and orange work best.
I spray with the powder electro stat gun.
I use 30# of air and put in wal-mart cheap oven.
400 deg for twenty min
I place them on a home a home built plate with dry wall screws to sit on.
More details if you contact me

MikeinNCI use Eastwood powders, I found the harbor freight stuff just didn’t work well...stepping up to Eastwood was like driving a pinto vs a corvette
I use the shake and bake method and don’t use a gun but just pour the powder into my extra tumbler and run them for a minute
I do it to 38, 357 & 45acp

TRshootemTried the HF red, worked just fine. I switched to the Eastwood Ford Blue for a overall smoother finish. For pistol bullets I use tweezers to place the coated stuff on a tray with a silicone baking sheet. Placing them base down in nice tightly spaced rows. They come out of the oven without sticking together and getting blemished.
This takes a few minutes longer than dumping them on a tray, the results are worth it

hairy2dawgI've used the HF powder, and it works fine if using the static sprayer, but didn't have any luck with tumbling.
My son was having some large fabricated items powder coated at a professional shop, and asked if they had any leftover or older stuff that they wouldn't be using. He came home with about 20 lbs of various powders that tumbles like a dream. Needless to say, I probably won't use the HF powder anymore.

FN in MTDo you then SIZE after one coating?
Dry tumbling is far more attractive than solvents....Thank You

The powder my son brought home seems to coat completely with only one tumbling. The coating is much thinner than spraying. I used to have to size in 3 separate increments, now I can size it only once.
