Not happy with the results of tumble lube on my normal-grooved bullets, I modded my mold to divide the large groove into two smaller grooves. They pick up tumble lube, great.
I decided to lube up some of the original bullets for comparison testing. After some playing around, this is what I came up with.
I added a little bit of nondetergent 30W oil to melted beeswax until I got the right consistency. I made about 5cc worth just for testing. Turns out it was just enough to finish this entire batch of bullets, including some waste while learning. At first I was just plunging by hand, and it required me to heat everything up with a heat gun, every few bullets. That was no good, so I attached the syringe to my press. It works cold, now.
I took some pics of the last one!
I found it's less of a mess if I do it in two squeezes. I give a squeeze, eject the bullet, rotate it 180 degrees, and reinsert it for the second squeeze. Then there's not as much lube pushed out past the bullet. Wipe the nose. Eject bullet.
