Hornady Powder Measure Binding with Universal
I am trying to throw 4gr Universal with the Hornady LNL Powder Measure on the Hornady progressive press but can't get through ten throws without having terrible binding and an extremely low powder charge. This doesn't make much sense to me because my go-to 9mm load is 4.2gr Unique, and Unique seems very similar to Universal.
I am using the pistol rotor and micrometer, pistol powder-thru insert, the powder baffle and I have degreased the whole thing multiple times.
Has anyone else encountered/solved this?
