No.4 MkI barrel to channel contact when trigger guard tightened down.

[muffett.2008]

Lack of contact or minimal contact of the left bolt lug will cause this with a number 4.
You can eliminate the wood fit by removing it and firing the reassembled rifle, support under the magazine, you may see a change but I would certainly correct the lug contact.

I spent an hour this evening shimming it and now have a temporary shim on the left draw. It didn't take much at all. This is giving me strong bearing on both draws.

I have also re-centred the front sight on the reference mark I made before I drifted it. I'll be able to get to the range over the weekend and see what effect this has had on the way it shoots.

The thing I'm wondering though is if this does fix the issue what's the best plan for a permanent repair?

I know the official armourers way would be to remove the proverbial gnats knacker of material from the right draw to bring the whole action back and get even contact. But I feel that this would interfere with the fit at the wrist which is very good.

I could glue the shim in. Or hell I could even use arcaglass. I have some laying around. It would literally take a drop of it to fill in.

I guess I'll worry about that after I shoot it and see.
