Talked to a member on here a couple days ago. He gave me some pointers on powder coating my cast bullets. Tried it out today. From what I think I heard, you do not need to lube after powder caoting, and they can be pushed to a higher velocity, and some other things I don't understand yet. So I took some pictures of the process that you might want to see.
First step, I had to build a holder for the bullets, so I used a aluminum clip board that had been laying in my way, and drilled some holes in it about 1 inch spacing. The hole should be just big enough for the nose to stand into without falling over, but not so big that the bullet will drop through. I am using a 30 cal. so each cal. would have a different size hole.
I put legs on the plate so it would have circulation around it and give me some place to hold on to, and a place to put the groiund wire. I sprayed the exposed area of the bullets with Mirror Red powder using a low KV . I then put it in the oven and set the temp for 400 deg. Once the bullets got to 350 deg. I set my timer for 15 minutes and lowered the temp. I need to say here that I don't care what the temp in the oven is. It can go to 500 deg. and I still don't care. I have a inferred temp gun. When my parts get to my target temp of 350 deg. I reset the oven temp so the parts will stay at my target temp. The instructions on the box of my powder said to cure it at 400 deg. for 10 mnutes. But 400 may be too high for the lead, so I cure it at 350 deg. for 15 minutes and get the same results. After my timer goes off I open the door and let it cool down before touchinbg anything. When cold just turn it over and the coated bullets fall off.
Simple right. So now my son n law will run his tests and tell me if it works for him.
If you want a little more info just let me know.
