You can buy enough powder coat for 30,000 bullets with $44.
I used to compete in IDPA and didn't have much room for high-volume reloading setups. I tried and tried to get LLA to work but it was always marginal at best in my 1911, and the competitors, many of them female, objected highly to the stench of Alox smoke. Along about the time I was winding down from participating in that sport, the paste wax/LLA/mineral spirits lube came along. It smokes less, dries faster, and works a little better than straight LLA. But I still have most of the 3-oz batch I made years ago and the most use it has gotten has been on paper jackets for smokeless powder loads.
BLL is a whole nuther kettle of fish, and I'm not sure it can be easily replaced. The polymer stuff in it together with the LLA does some magic. I don't know if the One Step is acrylic-based, urethane based, or what, but it is probably similar to Nu-Finish car wax except for petroleum solvents are used instead of water. Fiver and I have both tried to reduce the Nu-Finish to powder and change the solvent to naptha or mineral spirits, but neither of us had much luck with that. I did manage to get about a tablespoon of dry Nu-Finish to mix in with some LLA and dilute the whole mess with mineral spirits, but it had a tendency to lead like crazy due to having a very high CoF. A coated bullet just wouldn't slide on a steel plate, it grabbed like a rubber coating.
