Burleyboy, if you're satisfied with the tumble lube designs, they'll work just as well or better with powder coating. Personally, I've never found one of Lee's tumble lube designs that shot as well as its traditional grooved counterpart, whether powder coated or not.
If you try powder coating the way I do it, you'll probably not find any reason to tumble lube again; the process is very similar and takes about the same amount of time, but the powder coating is far superior and more versatile.
If you don't have somebody local to mill that mold, I can do it. Shoot me a PM if you're interested.
