If you use a Dillion press with a Dillion powder measure, you may find this interesting. I was reloading last night, and noticed that there was a light load at the bullet seating station, which is pretty observant with titegroup in a 9mm. Well maybe not really THAT observant, I had a another clue as well. I heard a "snap" while operating the handle, the kind of snap when the powder bar gets a little gunk on it and it doesn't return smoothly. In this case, the "snap" was during the "down" handle of the operation - not during the return where you might hear the "gunky powder bar snap". Here's what happened. There is a bellcrank on the right side of the powder measure which pushes the powder bar. There is a boss (the round stud thingy), perhaps an 1/8" of an inch long, on the end of the bell crank. This boss engages a slot on the powder bar to push the bar forward when the operating handle is pushed downward. The fastener (screw) on which the bell crank pivots became slightly loose, which allowed the bell crank to "wobble". The "wobble" would allow the boss to disengage from the slot before the powder bar moved the full distance to drop the powder in the case, resulting in a light charge. As a side bar, I use a very light application of dry graphite lubricant (the kind for lock keyways/tumblers) on the powder bar and the primer bar. Load carefully, Wanna kill these ads? We can help!
