No expert, but it sounds like it might fail the view portion depending on the severity if submitted for re-proof:

"View is a visual inspection by the Proof Master. If he thinks the barrels not sufficiently tight on the action, or he notices dents, pits or other faults, he will reject it as unsuitable for proof. If he considers it in good enough condition, it passes view and goes on to be submitted for proof."
