When you close the bolt, the lugs are touching the abutments. This is happening because the firing pin spring makes that happen. Take out the firing pin and maybe it can float.

The only way the bolt head touches the end of the barrel is if the barrel is screwed in too far. If case protrusion is correct you would not be able to close the bolt on a round. You cant rub the bolt on the breech and be able to close the bolt on a round unless it is chambered long.

This makes this statement untrue.
