Agreed. Get the micrometer drums and especially the small one. I have several of the older big drums and the lock screw adjusters. They were the first thing I pulled on my uniflows.
I should mention that my pistol uniflow is coming up on 300,000 rounds made. I am sure it has dispensed more like 400,000 rounds since it always takes a few extra to build up the setup.
These things take a bit of time to wear in but are lifetime investments.
10mm and 357sig, the best things to come along since the 38 super!
