Looks like I need to find a toaster oven.
So if I'm powder coating them,
does it make sense to reduce the depth of the lube grooves to get more volume in the boolits? I should be able to take them down considerably without increasing the bearing surface on the lands. I've seen where tumble lubed boolits have less groove area than wax based lubed ones.
You can certainly remove the lube grooves if you want a little more weight. The grooves are completely unnecessary with powder coating, and more bearing surface on the lands is a good thing.
Skip the wet tumble powder coating, unless you just enjoy a mess. Dry tumble in yogurt or sour cream plastic tubs, and bake in a powder oven on a piece of screen; it doesn't get much simpler than that. By "dry tumble", I mean shake it like there's a snake in there and you're trying to kill it, for 10-20 seconds, then dump them out on a baking pan with some screen in it. 20 minutes in the toaster oven, then bust them apart and size as needed, and you're ready to shoot.
Also, pick up a cheap $5 oven thermometer to figure out where to set your toaster oven to get a stable 400* F. Do not just go by the markings on the oven, they are usually wrong.
