One thing to know about Krags, it is getting very difficult to get brass
I would expect your rifle was unbreeched, a few thousands of an inch turned off the breech and re-chambered -- that's what the best rifle smiths did with Krags.My Krag bolt bears on both lugs. This was proven with some marking fluid. Don't know if it was lapped or not, but it definitely does NOT have excessive headspace. The bolt will not close on a round that has a .003" shim placed on it.
