For those who haven't tried the Hi-Tek coating, I highly recommend it. It's easier to apply than powder coating, and you can coat in different colors to distinguish different loadings. I coat bullets in black for my loads and red for my wife's in 9mm. For .45acp, I use black for my G30s and red for my G21. The bigger gun needs about .2 more powder to operate. The colors keep me from getting them mixed up.
