"IMAC" - Welcome to the KCA Forum and congratulations on your 'new' Krag. A lot of us enjoy pictures .... hint ... hint! Your missing swivels can be got from vendors in KCA Classifieds.

It is normal for a U.S. Krag bolt to have a bit of back & forth movement, when there is no cartridge in the chamber and the striker-mechanism is 'un-cocked'.

This is not noticeable, when there is a cartridge in the chamber and the striker is cocked.

IMHO - A good indication of U.S. bolt fit is to put the 'bare' bolt (with striker mechanism removed) in the receiver. Then check for a gap between the rear of the rib on the bolt and the receiver wall.

On U.S. Krags there was an intended gap (usually .002 to .004 inches in my experience).

If the rib makes contact, the forward locking lug may be worn or been lapped and 'head-space' might be excessive. (In my opinion, too much has been made about head-space in rifles with rimmed cartridges, like the .30-40).

Note - Norwegian and Danish Krags were fitted at the arsenal so that the rib on the bolt makes contact with the receiver. There was a time when civilian U.S. Krag owners lapped their bolts to achieve contact. This was believed to make the action 'stronger', but, probably just created more 'brass stretch'.
