For quite awhile awhile I did as you did and stood up every individual boolit. Eventually I got sick of it and figured I would try and dump them into a pile, put a fan on them, and see what happens.
The results were very good and I now use the "pile method" when drying all my boolits. Yes the lube gets a little lumpy in some places, but that gets all smoothed out when you put it through the sizer die or it gets shaved off when you seat the boolit. I have noticed no change in accuracy, it saves a LOT of time, and it basically eliminates my least favorite step. (standing the boolits up)
Some important details for the "pile method".
*My lube mix is Johnson's paste wax, Vaseline, and some Lee Alox. It is a bit thicker than straight Alox so I don't know how well it will work for you.
*Don't put the boolits to dry in the sun. The lube gets too runny and runs off. Put them in the shade and put a small fan on to blow air over them.
*When I say "pile method". I mean literally. Pile the boolits so you have a flat pile that is several boolits thick. Surface tension will keep the lube in place while it starts to dry. After it has dried a bit, a day perhaps, you can "rotate" the pile by smoothing out the pile a bit so the boolits can dry more completely. The lube at this point is thick enough that it will not run.
* Don't rush it. When I tumble lube I fully expect it to take a few days to dry. yes you can rush it a bit so it takes a few hours, but the extra effort isn't worth it. I have more time than money.
Try it out and see how it works for you.
