I take it that most people who are powder coating their bullets are using the polyester powders with the TGIC cross-linkers. The only drawback that I can see to that is that TGIC is the mother of all carcinogens and without a really, REALLY good mask and extreme care in handling it's really tough to keep from inhaling it. For men who are still trying to father children, (like me), TGIC could be a particularly serious problem.
As a solution to that problem, some kinds of PC have been formulated to be TGIC-free and thus a lot less harmful. Problem is, like most things, that kind might not be as good. I also have found that there are acrylics and polyurethanes, as well as epoxies and hybrids. The epoxies are supposed to be hard and brittle, I would think that's not a good thing (HiTek anyone????), though the urethanes might have some promise and the TGIC-free polyesters might be fine, too.
Has anyone tried out powders that they know to be TGIC-free? I ordered some polyurethane a few days ago and will give it a go, will report how it does when I get around to using it.
