I'm pretty new to powder coating. I used HF red and shake / bake method. They look good to me, I get a pretty even coating. Today I fired one into jugs of water and was surprised a bit of the result.
I cast old wheel weights, and air cooled them. Powder coated. Cured at 400 for 20 minutes. I "thought" that when running the bullets back up to 400 and letting them cool slowly, they would be pretty soft. Boy was I wrong.
This bullet went through about 20 inches of water and down into the hard GA clay. I was surprised, it looks like I could load the same bullet and shoot it again.
It is a Lee 310rf gc design, no gas check. Ruger SBH 7 1/2", 17gr 4227.
I would love to have my bullets mushroom in hunting situations. I think I'll try pure lead with powder coating.
By the way, I have shot pure lead slugs and they work well on deer. But un-coated will lead the barrel, obviously.
I am interested in your input. Dan
