Off face problem

[Tom]

Hi
I have been working on this project gun for a while now. I put a set of VH barrels on a DH, the face was loose so I epoxied a .004 shim onto the lug. I was very proud of my smoking and fitting the barrels, they came out nice and tight.

I just finished my tenth round of skeet with the gun and broke it down to clean it, the shim is gone !! Barrels off face again a complete waste of time. I deserve it for putting my faith in glue.

I am looking for advice on fixing it right. Can anyone tell me what actually wears, the hinge pin or the barrel lug ?

I hesitate to remove the pin for fear of buggering up the screw slot, but I will if that's the worn part. I was thinking take out the pin and either replace it or weld up the worn area and dress it back down.

If it's the barrel lug the only thing I can think of is to put a few beads of weld in the crescent area and again file most of it out until I have what I need.

Any advice greatly appreciated, thank you, Tom
