Go for it with powder coating! It’s great. A lot easier and less time except for getting another mold. Then you will have to think about boolit lubing. That takes time and money to get set up.

I use a regular oven, not convection. I don’t use BBs. I don’t need them. I use a silicone pad, but non stick aluminum foil might be better, because it lays flatter. Keep your powder extremely dry. I add silica gel packs from China that are really cheap to all my powders and more in a second bag I put the first into.

Try it you’ll like it.
