I've tried several products to lube my PC'ed bullets with prior to sizing. The product I have had the best success with is Lanolin Cream, the product used by nursing mothers when they get sore. Lanolin Cream can be purchased at just about any drug store or wally world pretty cheap. It has about the same consistency as Vaseline. When my bullets are still warm from the oven I put them in a plastic coffee container and add a very small amount of the lanolin cream then place the lid on the container and roll the bullets around till the cream is evenly distributed on the bullets. If there is too much lube on the bullets just add the next batch of bullets to those already in the container and don't add any more lube. It doesn't take long to figure out the proper amount of the lube to add per batch. I have even used this cream as a lube when swaging. The cream is nearly pure lanolin. Heck, even Dillon case lube is just lanolin added to rubbing alcohol. The alcohol evaporates and leaves the lanolin to remain on the cases.
