During WWII, it was common practice to tape or otherwise cover cannon and machine gun muzzles on fighter planes to provide a measure of freeze protection and to indicate at a glance to ground crew whether they had been fired.
Many armies also issue muzzle covers that can be shot through.
I agree that the column of air in the bore likely blows out the tape before the bullet reaches it. I wonder if anyone has done any high speed photography to confirm or deny this.
