The Zero Check Thread

[Ground Control]

This is an interesting thread .
I’ve used Leupold scopes on and off for about 35 years .
I can’t say that I’ve ever noticed any wandering zero issues with them .
One observation that I have in regards to the current move to larger group samples is the variable that gets introduced when overlaying multiple groups . When you break position between each group to reload your magazine/ let the barrel cool down etc your position/ setup / shooting form has more chance of introducing a zero shift than your Leupold .
I did a test a while ago where I stood up / lifted the rifle up off the ground between each shot , then had to reset myself all over again .
That 10 shot group was noticeably larger .
Scope mounts / bases have actually caused me more grief over the years than any of my scopes ( Zeiss/Meopta/Leupold/Swaro) if I’m honest .
