Don't dip too deep. I try to stay just below where the bullet diameter equals the caliber. Doesn't seem to matter much in revolvers, but some pistols get cantankerous. It runs through my Ruger MK II like fat through a goose, but my neighbors Walther PPk will start misfeeding after 3-4 rounds if they are dipped too deep.

Several brands of factory ammo use those plastic trays with holes in them in their boxes and I occasionally do the same trick to FMJ in other calibers.

I also use thinned out LLA to tumble lube the pre-lubed cast boolits I reload with.

Back on topic.

I've tumbled loaded ammo in the past, but these days I just make the brass shiny and slick so it loads easy.
