give up on the 2 disks and get the Lee perfect powder measure. Its under $20.00 at (insert mailorder place here)
I run H4198 through it all the time, works great. Some talk about a little powder leaking out, Maybe it does but not that I have seen.
I have also run H4895 and trail boss through it. I never took time to figure out how to read the adjustment, I just weigh several loads until it's what I want, then I start loading.
I have it working on the turret press in Auto charge mode, but I still have to return the lever every time.
When doing rifle shells, I don't use the Turret press in auto mode. Problem is the handle hits on the primer feed if you have the press in Auto mode, Instead I decap, size, prime all the cases turning the turret by hand. Then I weigh each case on my digital scale, charge it, weigh it again, then seat bullet. I find once the Lee Perfect Powder measure is set, you never have to fool with the adjustments.
