Hi all, I’m losing my mind here and hoping you can help. I’m trimming some 223 brass with the Lyman Universal Trimmer and getting incredibly inconsistent trim lengths. The lengths are different both from one to the next, but also on the same case mouth from spot to spot. The trimming rod seems to wobbling and it looks like the lock nut is spinning off center, but I can't tell if it's an illusion or actually off, and if so how to fix it.
What gives? Anyone have any tips or advice?
