In a recent conversation I was asked if one could remove a scope from a M77 Hawkeye and replace it and expect a return to zero.
I have owned many MkII's and a handful of scouts over the years and it seems to me I tested this many years ago and came to the conclusion that, using the same technique to re-install my POI would always be 2-3" from my POA or Zero at 100yds.
The 2-3" shift could be in any random direction, and I recall thinking that a guy could still probably make a shot 200yds and in.

What are your experiences with the factory Ruger mount system? Has anyone ever tested RTZ? I'm thinking Hoyt must have some info?
 
The torque values of the mounting screws to the reviever will always be just slightly different when remounting.
That will change your "zero".
 
I have removed scopes in Ruger factory rings and remounted literally hundreds of times and always return to acceptable hunting accuracy. If this is going to be a practice however, I would learn a system of centering and torquing and consistently use that system upon remounting. A torque wrench is helpful in this regard, as is consistent pressure as you tighten the screws. The Ruger system is pretty good at finding center, given the curved shape of the hardware.
 
I wouldn't be comfortable betting a possible once in a lifetime shot at a trophy animal on an untested remounted scope.

To each their own though.

I've done it... I don't like doing it, I prefer to not touch anything once zeroed and tested, but the circumstances required it... there are just times where you really want to switch to the iron sights.

oh now, thats far fetched is it not ? lol.
just freaking bang one though it in the earliest possible chance you get BEFORE you go chasing the ones in a life time trophy animal.... i think 99.9% would attempt this after a complete scope off then back remounted on again scenerio.?

to the OP, ive not tried this at all actually. ... it would be interesting as Hoyt says the design of the mounts...

That is not the question in of this thread, the question was if it would return to zero.
It's either a yes or no answer, if you have to test it then the answer is no, it won't return to zero

It's either a yes or no answer, if you have to test it then the answer is no, it you dont trust it to return to zero

Testing it means not trusting it has returned to zero.

Would it be close, maybe, would using a torque wrench for assembly might help, but few carry one in their pocket in the field or have one in camp.

What percentage of gun owners have one even ?

There's a lot if guns out there assembled by the snug ir tight enough method even though torque values are available for most fasteners
