Recently while adding gas checks to some tumble lubed .25 cal bullets I made a serendipitous discovery. The gas checks were being applied by running the bullet into a sizer having a diameter the same as the bullet as cast. No lube was added in the process leaving only the liquid Alox film. Handling small gas checks always challenges my dexterity and often ends with checks rolling around the bench and sprinkled over the floor.
I was dumping checks into a lid then pressing the bullet base into the ones that were upright before seating with the sizer. Of course, about half of the checks were cup side down as dumped into the lid so to use that half flipping them over was required. This is where the dexterity deficiency was troublesome. Picking up each little copper cup to turn it over was not easy. My fingers were a bit tacky from handling the lubed bullets so I was trying to just press my fingertip on the check, have it stick as I lifted my finger to grab it, then flip it over. I quickly observed that with the right amount of finger stickiness, the check would lift a bit with my finger then come loose and fall back into the lid but would flip over to land "right" side up. Taking advantage of this discovery I was able to not only flip the checks very quickly but keep the little buggers front jumping off the bench most of the time.
This won't revolutionize reloading or even sizing and gas checking cast bullets, but I thought I'd pass it along in case someone wants to give it a try. It always amuses me to find some little kink or twist that makes a task easier.
