Thanks for info, I don't have a HF rock tumbler but I do have a spare vibratory tumbler. I think I will combine your way and Frank's method. I am going to dump the dry powder and boolits in the tumbler, let them vibrate for a while, then dump it all out on a wire mesh and catch extra powder below. then put them in the oven and hopefully they will not stick and have a smooth finish. If this works good, I will post some pics
