It may well be the bolt that needs attention, but note that the barrel flats should NOT be snug down against the action flat. There should be almost no daylight visible at the very front of the juncture, but an increasing amount visible towards the rear. This is by design. The "tightness" should be at the hook/pin relationship and the barrel breech/standing breech relationship. The barrels' breech faces should "seat" snugly and with much contact with the action breech, thus stopping the breech end of the barrel flats from contacting the action flats.

May God bless America and those who defend her.
