I adapt a Hornady or Uniflow powder measure with a Hornady Case Activated Powder Drop. I use TAC powder a very fine ball powder, it leaks, no it rains TAC from the OEM Dillon slides. Without jumping through hoops, buying and lapping aftermarket slides to the Dillon , which I'm not willing to do, BECAUSE I F'N HATE DILLON POWDER MEASURES. The Lincoln Log IMR4064 doesn't do well in the Dillon PM either.
I tried converting the Dillon PM back to the original Spring Return and got rid of Dillon's Jar-o-matic linkage. It helped but I still ended up throwing them in the junk bin.
The Hornady Match Powder Measure and the RCBS Uniflow , drop pretty **** accurate, doesn't rain TAC, and deals better with heavy stick powder.
