Remove the forend and hold the top lever open and also holding the barrel tightly down on the action see if there is any horizontal movement (side to side) in the barrels. If there is any movement then the gun is off face. With the forend off and the top lever closed see if there is any vertical movement (up and down) in the barrels. If there is then most likely the locking bolt is either worn or confirmation the gun is off face. Refitting the hinge often sets the barrels back far enough that the locking bolt problem is solved.

It ain't whether you hit a bird that matters, it's the fun you have even if you don't.

Place a one thousandth inch feeler gauge across the standing face. If the gun will close on this gauge, it is off face (and it may very well close on a thicker one).
End of argument.

There's a long list of things Dewey does not approve of. And, no one alive, besides him, know what they all are.


May God bless America and those who defend her.

I tend to sympathize with Dewey - when one does a job properly, one gets tired of seeing the half-assery and advice on how to do it on the cheap. There is no "good and cheap" in the fine hand built gun business. I was in it long enough to know.
One thing's for sure, you ain't going to wish it back on the face....

here's how i see it...

when a gun is fully assembled and ready to fire...and one finds the barrels wiggle, it is an indication that the bolting system is worn and in need of repair...so long as there is no day light between the face of the action and the breeches of the barrels the gun is not off face...

once daylight begins to appear, then the gun is off face...wiggle or not...question is, how much day light is unsafe? .004 is the number i remember from years ago... in reality, any day light, even .001 makes a gun difficult to sell...

as for fixing off face...hinge pins are hardened...barrel hooks are not...so it makes sense to add metal to the barrel hook before rotating or replacing the hinge pin...

mike, good and cheap has its place...

beer can shimming of the barrel hook, which can bring a gun back on face, will work for some..and when done multiple times can become a routine semi permanent fix...

welding up the barrel hook should last much longer than a beer can shim...

and if neither of the above do not work, then hinge pin rotation or replacement seem to be the last resort?

is mike rowe your real name? and when and where did you create fine hand built guns?
