I've notice a strange thing on my 6-24. I set up my elivation zero stop and just like the manual says, I can turn past zero 5-7 clicks. Every time I rezero that number decreases though, yesterday I brought I back from +12.3 mil and almost had to force it to zero. I don't understand why this would be happening, my zero holds so I don't thing the turret is spinning free and my data holds up as well (two hits at 1050 yrds with the +12.3 dope in full value wind!). What the hell is going on?
