Here's how you load stick powders on a dillon progressive.
Eppie, Which progressive are you using? That older model Hornady measure teamed up with the old model CAPD,(Case Activated Powder Dispenser), on my 650 loads varget +- .2 for 69 match .223. I did an experiment with those loads, IIRC it was 24.0 grains of varget,(look it up, my memory is terrible and I'm too lazy to go look)
, I weighed 10 rounds with a pact dispenser, and ten run with the Hornady measure on the press. No difference in velocity OR group size.
