Parashooter,
I have one of those 67 Winchesters. It was my mother's gun and given to me when I was 8! Would not be politically correct to give a child a rifle today.
It would certainly require a smaller hole to fit that into a Krag stock. Also it is fairly strong as I do not think any looseness has developed in mine. I can think of a couple of down sides,
Driving that dovetailed stud into the barrel will cause stress on the barrel actually bending it. How much? I do not know. Now we are back to a machinist or gunsmith doing the work.
I would like to this to be something a careful person with a few hand tools could do in the garage and get professional looking results.
When Dick mentioned using a brace and bit, it gave me an idea on a couple of hand cranked cutters that would make the job easy with the Savage band. Did a search for inletting for this Savage band and found nothing but saw a photo of bedding done on both sides afterward. Not a bad idea if Jim's stock is free floated in that area. Also I found mention of barrel bands being added to Krags and the reason it was a good idea but that was it.
