Was setting up the press for a different 9mm boolit tonight, and made 6 dummy rounds to check for chambering in my pistol. When I measured the OAL, I got quite a spread: 1.078, 1.079, 1.1.083, 1.084, 1.088, 1.088.

These aren't difference immediately obvious to the naked eye, but I've noticed this before when I've taken the time to check OAL. Is this spread normal? Is it a problem?

You might want to check your seating plug for boolit loob. A buildup will cause that kind of variation. Also, make sure your seating stem is secure.
