kBob story warning!
Mid 1970's and Drewsy and I are training with the Company at Hohenfels and stuck out on a "Combat Out Post" with out M16A1s loaded with blanks. Now unlike a listening post at night or Observation post in day light, a SEE OH PEE engages the enemy to force them to depoy into assault positions and slow down giving the defenders a heads up and time.
We were getting scattered showers and it was misserable, but happy day they sent out B rations! That would be a Ham & cheese sandwich and a bit of fruit. Drewsy and I had a little picnic and I had a Darned Old Duck orange juice in those little cans for my fruit. Having drained the can I pulled out my P38 Shellby can opener on my dog tag chain and cut the holed top out of the can and washed out the can with canteen water to both clean the can and get another half an of amazingly weak "orange juice" I was debating opening the other end of the can when it started to rain. Now we had black plastic covers they issued when we had live ammo because of the fear of water as a barrel obstruction (hey it was in the comic book manual) but on blank training excercises they stayed in the crate in the arms room.
It started to rain again and heavier than in the morning and the NCO that brought out our picnic said we could not keep our rifles under our ponchos any more
ah ha! I have the Darned Old Duck prepped for use as a sloppy fitting muzzle cover.
A bit latter Drewsy signaled me that he had movement on his side of our half volkswagon beetle sized rock. I peeked around and from my angle saw nothing. As I turned back to my own sector an "Aggressor" stepped around a bushy tree only about seven yards away that they had not let us clear. He was stareing at Drewsy's end of the rock. So I did a quick point and pulled the trigger.
The "muzzle cover" flew straight and only dropped a little to smack the opposing kid just over the belt buckle. He staggered back a bit in shock to be hit and to see me....fired a burst of blanks in my general direction and started screaming "I got You!" like eight year olds playing army in the back yard.
That was my most fun with a Muzzle cover!
We did take the black ones on a range and have four guys shoot through them at 100 meters. All hit a kneeling man reactive target at that range and three of the covers took hits while on or near the muzzle and none went more than 10 yards down range. One was neatly holed in the center like it had stayed on until the bullet passed, one near the edge and one on the side. The oone un hit was actually closest to the firing line.
On an Occasion at Graffenhower when we had to pull live ammo stuff occassionally but were mostly using blanks for training one guy had a Muzzle cover in a blank loaded rifle in a nice comfy hole in the ground. A useless driver/clerk that seldom did field duty wandered over and started talking to the guy with the Muzzle cover. I was running wire from a donut roll to link holes in a hot loop with a sound powered phone in each hole and happened to be tying off to a blue berry bush immediately behind the hole when the conversation went down hill.
Remf: Hey Old Man, what do suppose would happen if you shot that gun with that muzzle cover on it?
Old Man : Umm, it would just blow the cover off.
Remf: But what would it do if you shot some one with it?
Old Man: you really want to know?
Remf: Sure.
Rifle: BLAM!
Remf: AAAAIIIIEEE! I'm SHOT! (falls and rolls about on ground screaming)
Seems the answer to the question was from one foot away it would bruise the leg just over a boot top all the way around and cause victim to be exempt from military duties 24 hours and on light duty for several days.
I finished wiring in the platoon and went back to my own hole where as I approached I asked my Battle Buddy to point his muzzle covered rifle 180 out from me.
A couple of years later while stateside I noted that all the muzzle covers were red and wondered if that was to remind folks the had one in place.
