Just for the benefit of anyone who was interested in this discussion, I thought I'd post a little info.
First, the powdercoating of the unlubed 148gr LWCs I picked up at the gunshow is going swimmingly. See the attached photos of a tray full of the bullets ready to bake, the tray fresh out of the oven, the smash test on a couple, and a closeup of one of them.
I've only done an experimental batch of 50 and one full batch of 100 so far but since I can fit 100 on a tray, about 3 more batches will finish them off. I'm borrowing a sizing die from my buddy since they'll still need to be sized before loading. The coated bullets are measuring out at .360
In regards to trying to powdercoat some that are already lubed and sized, I am experimenting with a few hundred slightly undersized (.427/.428) 200gr 44 cal bullets that I bought at a very discounted price. The lube on them is old and brown and sticky. I first tried the suggestion of boiling a few of them in water to remove the old lube, but after 10-15 minutes at a hard boil, less than half of the sticky gunk had come off and floated to the top and the lube grooves were still full of lube.
So, I decided to try dropping a few others into a little container with some gasoline. In just a few minutes ALL the brown gunk was dissolved and the bullets looked nice and clean - including the lube grooves. So a gasoline bath followed by an acetone wash - as suggested on the cast boolits site - looks to be just the ticket.
Putting a 0.001" - 0.002" layer of powdercoat on them ought to bring them right up to size - and they shouldn't need to be resized afterwards.
