When I bolted my first blue press to the bench all I did was set the powder measure and seating die length. Then started cranking out ammo........NO tweeking.........No shimming ........No adjusting....No primer adjusting. That was 25 years ago. Same press is still cranking out good ammo. I had a pro 1000 given to me......Kept it about a week and gave it away. Not worth the hassle. Lee makes some good stuff that I use but I steer clear of their presses.
