Read my instructions a little more carefully.
Bullets are only rolled around in a pan with a few drops of lube for the whole lot. Just enough to make the bullet surfaces wet, no more. There is no excess to wipe off, no cookie cutter, no mess. What I hate most about it is it's cheap, cheap, cheap, and cuts into my lube sales like terror. I calculated once that one stick would lubricate 10,000 38 bullets.
You could size after if you wish, but it might be wise to lube again after sizing. Never tried it. I only shot tumble lubed bullets that would chamber without sizing, so experiment, and let us know if sizing knocks off enough lube to detract performance. I don't believe it will.
Oh yes. This is not for high power shooting. Best hardness is air cooled WW, or around 12 bhn. Harder will start leading at lower velocities than at 12 bhn. Unlike bullets which have the grooves full of lube, we don't have hydrolic lubrication with this method, so keep pressures where they shoot without leading. One should be able to get 1000 fps quite easy from revolvers, without leading, and in cool temps up to 1300-1400 fps with slow powders.
DO NOT TRY IT WITH ANY OTHER LUBE BESIDE LBT! What I'm writing applies only to our super strong bullet lubricants, any of the three, commercial, blue or blue soft. All others that I'm aware of barely make it when used with heavy coatings or grooves filled.
