I will never again in my life hunt without taping the end with good ole Scotch 33 black vinyl electrical tape. Was sitting while hunting and dropped my rifle muzzle down and ended up with a mud plugged barrel. Thankfully I was able to modify a green branch from a sapling and cleaned the mud from my barrel, then used a disposable glasses cleaning patch to swab out the bore. When hunting out west or with mu .50 cal ML's I always taped the muzzle, but rarely while deer hunting back home. Not any more.
