no real way to fix that, the rifle in question was a grandpas gun deal, so, i turned the shoulder and breach face back, recut the extractor, with the agreement that it wasnt going to be shot on a regular basis anymore,
the bolt set back wasnt as bad as the the one i have pictured, the worse issue was the over sized chamber, that combined with bolt set back, and alot of hard use.
you can see the case, just how far back it was set.
i normally wouldnt have repaired it, some have tried to weld on the ways, and mill them back to spec, with mixed results, with the amounts of 17s and 14s available...its best to just retire the ones that are worn out.
worse part about it, the only real way to see how bad the set back is, is to remove the barrel, and look, i feel it with my finger nail to see if i can feel a ridge, and take it from that point.
