Well I finally got round to going up to the gunsmith to pick up some other bits and pieces. He didn’t admit defeat and the action has now been repaired and you cannot even tell it was cracked. The crack was on the front of the action. When it was converted to 410 the action gape was widened and extra pressure was being put on this bit. It’s not structural so I think this project is back on. Now 22 Hornet or .222?

And for the scope mounts do I use simple Parker hale style v blocks or go for some sort of claw. The German claws I think would be wrong, the Holland type a maybe but most I have seen are simple v blocks. I have a straight tuned Nickel Marburg 1-4x20 which will fit nicely.
