Sorry for the delay responding, had a death in the family but it was expected.

More on 105621, I don’t know the history, it was bought at a gun show (truly a “show special”, appropriately priced in hindsight) at the end of 2016 and am just now getting to it, but it does not chamber a round (bolt won’t close on a round) but bolt closes OK without a round. See pix, this round is pushed in by hand, looks like 1/32 is exposed past rim (tried several rounds, none fit in 105621 & all chamber smartly in other Krags). I swapped bolts around for completeness, same results. The rim of the round is well clear of all metal so the issue is in the chamber. At this point I’m taking BRangers suggestion of a cut-down & re-chambered barrel as gospel (originally a 30” and cut at both ends to result in 22”). The original index mark on the barrel is missing but what looks like an extension of the mark is scribed into the barrel (for use later after the original chamber was cut off & original index mark gone). So guessing this barrel needs to go, suppose best replacement option is CMP/Criterion but as always suggestions/guidance is appreciated. There are no blockages in the chamber, chamber walls are smooth & polished & “look OK”, whatever was done seems intentional yet the results are the results. Wondered if it was chambered for a different round but can’t think of one that is only slightly smaller than 30-40.

As for the receiver…there is no ‘P’ mark on the face of the receiver and the index mark on the face of the receiver is not there (but there is one on the side…see pix). If all that is supposed to be on the receiver face then I suppose some metal has been removed from the face as part of this hack to get everything to index marks to line up. Looks like the barrel should is 27/32” (see pix)…WHAT SHOULD THIS BE & IS IT “OK”? Also reflecting on MShooter’s comments of ‘feed ramp work’. Rounds do feed & eject OK, with & without magazine cut-off …so is this receiver still "OK"?
