How do you tell if the front screw on a scope mount is too long? I have 2014 Model 111 in 7mm rem mag with Ken Farrell mount and rings.
If front screw on a scope mount is too long, what will the screw rest against?
What will this do to accuracy?
Is the front screw typically shorter than the other three?
If it is to long it will stop when it hits the barrel threads. This will also prevent the mount from being tight and mare the barrel threads if you remove it with the mount on. Either find a shorter screw or cut some of the long one off.
Yep!
Dremel tool time.
1. The barrel threads. If the rear one is too long the bolt lug with hit it.Quote:

A depth gauge

As usual, Bill Pa has "the" answer! :)) I'm not set up like that, so I just stone all of mine shorter to a length where I am sure they don't bottom out.
Hey FW, you can do the same thing with a small O ring and a #6 finish nail. Its how I checked them before I made that depth gauge.Quote:

Without the base, take the base screw and just barely start it into the action, count the number of turns required to bottom out on the barrel. Remove screw, place mount on action, insert screw through mount and count number of turns needed to tighten mount to action. If the number of turns is less, you are good to go. If not, the screw will have to be shortened.
