I picked up a new Dillon a few weeks ago and got a chance to chronograph my standard 9mm load over the weekend.
9mm Load specifications.
4.3 grain W231
Federal 100 Small Pistol Primer
124 grain Berry's Hollow Base Round Nose Thick Plated
COL 1.150
Chronograph Data:
I am pretty happy with the consistency. I am not sure if you can expect any better out the machine.
I am trying to target an average velocity of 1050 so based on some of my data collected previously I am pretty sure I can drop my charge to 4.2 grain of W231/HP-38 and get closer to 1050 without dropping below that.
