Odd situation on 550

[Wanted]

I've been running some .45 ACP lead bullets on my 550. Iv'e adjusted my seating so I'd get an OAL of 1.25 After running some they were 1.26. Again I'd set it for 1.25, again they came out 1.26. Three or four times this happend. No big deal, when I drop em im my barrel they are even with the hood. I just thought it was kinda wierd.

When you set it to 1.25, did you have all four stations loaded?

yeah, it's typical of a 550. I usually set it about .005 under what I want it to be. Movement in the toolholder and I suspect applied pressure differences between running one shell for set up and all stations filled in progressive

It was the only station I had on. I think I see what your getting at. Didn't know that you needed something in all of the dies. Makes sense though. Thanks
