So a scope getting whacked on the elevation turret with a rock is the same as carrying a rifle by the scope?

One of the valid ways to use a collimator (which so many people refuse to do because they can "bore-sight" the old-fashioned way) is to put one on the muzzle of a rifle in a vise, and then how doing various various things to the scope affects how the reticle lines up. You can make the reticle do all sorts of things just by pressing the top of the adjustment turrets in some scopes, or pressing the objective and ocular bell in different directions. But damn few scopes change POI just because we pressed on them a little.

This is because even big, tough scopes have to be a little flexible to withstand recoil. If manufacturers actually made them super-stiff, all sorts of problems would appear.

I'm one of those ignorant nitwits who does carry a rifle by the scope occasionally, and have yet to experience a change in POI. So +17, or whatever.
