For normal powder coating applications they are probably all equal, but in my experience they do act a little differently on bullets. There are a couple characteristics that matter:
- dry powder adhesion to the bullet
- ease of breaking stuck bullets apart after baking
- toughness of the coating in the bore
Since we're using the powder a bit differently than it was designed for, we might be seeing differences that don't show up for a normal powder coating use. The white and candy blue colors I've tried, for example, are tough and coat well, but stick together so badly that they aren't practical unless you want to separate all the bullets before baking.
One other color that works really well for me is a dark metallic green, also from PBTP, but I haven't used a lot of it since I'm not sure if the metallic particles are abrasive. (they may be plastic and harmless, I'm not sure)
I just started working with a "Bottle Green" from PBTP, it seems to work well so far but I don't have much time with it yet. It's sorta between Olive Drab and Forest Green.
Just experiment with different colors, they aren't all the same but I think there are probably lots of them that work really well.
