Before you fellows offer more repair strategies you might reread Jim's initial post.
"There is no real fix to the problem short of restocking the gun" I would agree.

This was a custom project I'm quite sure Jim had a couple of hundred hours into and I would simply consider "ruint" If you search his previous posts you might get an inkling of his investment in this particular rifle project.

If I were the checkerer I might be trying to buy that stock out of circulation
