Do you have multiple powder measures for your progressive press?
I just bought a second powder measure for my 550B. I plan to use one powder measure for large rifle cases and one measure for small cases.
This seems logical and I assume it can help save time when moving back and forth from small to large cases....
Swapping out the large and small powder shuttle in the Dillon powder measure is a PITA, so this is a solution to that, I suppose.
Anyway, it does not seem to be a waste of $. It took about 6 weeks to get this powder measure from Dillon - yikes!
