I have a curious question. It is possible for a 9mm dropped onto the floor from about 3 feet to fire?

Actually it was a box that was dropped and 2 rounds fired. This is the ammo in question.

I apologize if this is located in the wrong thread.

It is possible or is it possible? If this happened to you, there's your answer. Not trying to be a smarta$$ or anything, but I do not recall of hearing this happen. But, there are a lot of people on THR that are a lot brighter than this burnt out old bulb that will more than likely pipe in soon with good information. BTW,ammo brand or reloads?
 
What kind of box/package was this in? What kind of floor? That's a pretty rare occurrence to have happen once, much less two at the same time. Live ammo gets ejected out onto the floor regularly when someone experiences a failure to feed, or a failure to go into battery.
 
Ammo dropped can fire. I've seen it happen on two occasions. You've apparently seen it on one already. All it takes is a whack on the primer. However, as you note in your pictures, the result is ruptured cases and the bullets do not travel far at all. The biggest danger is from pieces of brass casing and even that is slight. I'm not going to go outside and begin throwing ammunition in my driveway, but I'm not going to get all paranoid about it, either.
 
I droped a ruger 10-22 mag when hunting one year the round went off. I got home pulled my boots off and my left boot was full of blood. The 22 hit me right where i had old stiches form a bike wreak i had about 5 years before. The spot is all num just on the right side of my left knee cap. The bullet went in about 1/2 inch. It was winter and i had on long johns and black jeans. So ya if they land right they can go of. But most times there is no power. The brass is most times the thing that goes flying. I was in the fire department and have had ammo go of very close to me. shot shells make a good boom.
 
It happened where I work. We store ammo in a locked box until it can be taken to the sales floor. When the box was opened the box fell to the smooth concrete floor and you see what happened. The brand was Federal. I was thinking that maybe it was faulty ammo or something. That is the reason I asked. I have never heard of this happening before.

Thank you for the welcome!!!!
 
Obviously, yes. A safe bet here is that it hit a rock or something, or a primer was proud of its pocket and took the blow.
I consider it likely the second one was probably sympathetic, not necessarily a second ignition. I assume they were next to each other in the box?

I am amusing they were next to each other.
 
There is a basic rule of science -- If a thing DID happen, it COULD happen.

The rounds shown are typical of rounds that go off outside a gun -- the case walls blow out and usually the bullet stays right there -- no damage other than to the two cases.
 
Primer goes off in a Purse!

A Pennsylvania woman was shot in the leg while shopping at a local department store on Tuesday. But in a nearly unbelievable twist, no gun was involved. Apparently, the woman was carrying the bullet in her purse, when it mysteriously exploded.


"She did not have a gun in her purse or on her," Montoursville Deputy Police Chief Jason Bentley told the Williamsport Sun-Gazette. Bentley said the woman, whose name has not been released to the public, "was not aware" she was carrying two or three bullets inside her purse at the time of the accident.


The 56-year-old woman was taken to a local hospital and was eventually discharged. In fact, the woman initially declined medical treatment, only heading to the Williamsport Regional Medical Center after her son reportedly encouraged her to do so.


"Something must of hit the primer of one of the bullets," Bentley said. "The bullet stayed in the purse, but its casing put a hole in the purse and caused a minor leg wound."


Bullets exploding outside of a gun are a rare occurrence but are not entirely unprecedented. In March, a bullet being used as evidence in a court case exploded in a bag and shot 20 feet across a courtroom. No one was hurt in the incident. It was surmised that the bullet exploded after its tip bounced against another bullet tip in the same evidence bag, according to the Telegram & Gazette.
 
Apparently you did not have to look very far for the bullets. Is it the lighting , or are those 2 dissimilar bullets? If so , how did that come about?

Probably reloads without the primers not fully seated. They were sticking out about the base of the cartridge and the impact was apparently enough to set them off. Kind of hard to believe because a primer usually needs a hit from a firing pin near the center to go off. I would like to see the primer side of the rounds pictured to see what happened.
 
I know of one verified incident that a 40 S&W round went off when dropped from about 4 feet. I've got over 40 years as a LE firearms instructor and know at least several dozen other firearms instructors. I also had over 40 years with AD, National Guard, and Reserves. I've been around a few million rounds being handled in my time. I have reliable knowledge this happened once.

So yes it can happen but is not likely.
 
The OP suggested that the incident occurred in a retail establishment , having said that the ammo was being taken onto the sales floor. Reload with mixed bullet types , retail?

More information would be helpful in understanding how the incident occurred.
 
I have reliable reports of ejected cartridges firing when landing on gravel so that the corner of a rock could act as a firing pin.
In the box on a flat floor is a new one on me.
Note that Federal primers are more sensitive than other brands.
 
We used to set off .22 lr cases after we'd pull the bullets to burn the powder for fun, by repeatedly throwing them at the ground and always got em to pop after a while. And tried it with 9mm primed empty cases we found in middle school. So yes it can happen very rarely with out deliberately trying.
