For almost as long as I have been casting boolits I have been a Lube Size guy. Even made my own hollow lube sticks.
Been contemplating for some time, been reading the treads here.
I found Sherwin Williams Powdura TGIC Polyester Powder on a popular on-line auction site. Three colors arrived today, Red, Orange and White. Price is $6/Lb plus shipping. Also available in 5 pounds packages.
Coverage was good with and without the airsoft pellets. White was a little light on coverage, but it may have been some contamination in the bullet. I didn't boil that batch twice after running them through the sizer.
Bake temp is 375 for 15 minutes, I ran 20 minutes to get bullets up to temp.
The coating passed the smash test.
As for my thoughts on the whole process, all the sizing not saving me time on the bench. I sized the bullets before coating using a lyman 450. I removed the center of the sizing die and just pushed bullets through, one on top of the other, letting them drop in a container below.
I undersized 30 cal to .308, 38 cal to .357 and 44 cal to .429 figuring diameters would grow with coating.
Only one batch of 38s, had a light coating, grew to .359. All the rest need another run trough the sizer. .429 grew to .433
