Rifle Scopes Does long road trip cause a shift in zero ??

[Baron23]

Thanks for sharing this...superinformative. However in my case, I am using AI AXMC (multi caliber)...while reinstalling barrell you do not have to torque it...barrel is hand tightened only. There is a reasonable chance that the hand tightening might have come loose over a 4 month period while being in trunk and also making a 3000 mile journey.

Don’t understand. If the barrel came loose, did it hold zero after rezeroing it when you found it shooting 20” high in Seattle?
