How to Zero a Scope

This is a refreshing video in that he didn't attempt to zero he scope with a mirror to get it exactly centered before mounting it. Then, due to differences in barrel position, scope mounts and the rails on the rifle itself that the gun mounts to, you have to twist the dials to get it properly zeroed on target, negating the mirror zero.

The only way to mirror zero and keep that intact is to use adjustable mounts and bring it real close with them, so only a small click or two in either direction brings it in.

I very carefully take the scope adjustments to both ends, stopping as soon as the slightest resistance is felt and go to the mid point from there. Some say bringing a scope to the end of its adjustments may destroy the scope and that could be true if you bull your way to the stops, but in all the years of scope mounting under my belt, nothing has been wrecked.

Your argument doesn't make sense to me. Centering the scope reticle using the mirror method, no matter what you do with the scope after that, is still better on the scope mechanically than turning the turrets from stop to stop, then back half way. Whether or not you personally have never had a problem doing it that way.
 
Nice video. It will help someone if they follow the simple steps you mention.
One simple thing skipped in the video. When I test my scope for vertical, I do use a string. But, it is important to tell beginners to make sure they put a level on the gun first. :) the gun itself has to be level before the reticle can be made level. 

Thanks Joe. Keep cranking out the helpful videos. I appreciate your contribution to the community.

@joewaynerhea, as always (well, almost) you've given us a great video for air gunners to reference when learning the ropes. Simple steps, demonstrated and proven. Then your trailer bit freaked me out and left me scarred. I don't know if I'm going to develop a hand phobia or a hand fetish... either way, I'ma thinkin' it's not a good thing. You rule.
