Unlike Melnic, I just throw my bullets onto the hardware cloth, shake a little and put it in the oven. I bake at 400 degrees for 20 minutes. Yes, some bullets stick together. When I remove them, I bounce the tray on the floor and that makes the bullets separate. The little imperfections or bare spots do not affect their performance for MY shooting needs. I don't shoot precision targets. I shoot silhouettes at 7, 10 and 20 yards for pistol and at 50 and 100 yards for rifle. Since I mostly shoot double taps, I am not looking for 10 ring accuracy.
That said, when I originally did testing for powder coating, I found that weighed bullets, that were coated with a thin spray of paint, would hold their own against jacketed bullets and traditionally lubed and sized bullets.
One of the most important parts of powder coating is that you do not let the fore part of the bullet get too much paint. The reason for this is that the size die does not touch that area (unless you use nose size dies - a subject that needs to have its own thread) and, even though it can be loaded, will not pass a case gauge test. (assuming you use Wilson or better gauges)
