Out of Battery firing?
- Thread starter Don V.
- Start date
Don Welcome to this forum!
The Term "Battery" is from the Artillery Gun's.
Definition;
An Artillery piece in firing position is said to be in "Battery".
(This definition is from Olson's Encyclopedia of Small Arms 1985 John Olson)
To me that means it is loaded and the breach is closed ready to give the cord a yank.
Out of battery would be anything short of this definition and that would mean the bolt(breach-block) isn't fully closed and there was a discharge or detonation of the cartridge that could be the result of something striking the primer before the bolt closes containing the pressure inside the barrel/chamber or could be the result of a hang fire where the cartridge fires late and is in the process of being ejected.
There may be more examples.

Don, Wait until you start reading about handguns that are "Out of time."
Welcome to the forum. Very good question.

The gun fires before the bolt is properly locked ! Unlocked or out of battery.
Case can rupture and cause injury to shooter or gun.Repair gun immediately !
My buddy had a Jennings do this. Scary as hell once we figured out what was going on.
Wait until you see an M1 fire out of battery, or "slam fire". The round is detonated before the bolt locks. It will get your attention. Military, semi-automatic rifles can do this (depending on conditions) when a round is chambered and the bolt is closed on it.
I've seen two; one at Camp Perry, and one at Fort Knox. Neither was damaged, but the shooters were sure scared.

Out of battery firing in a revolver means the timing is late, the cylinder hasn't rotated far enough to lock the bolt into the locking notch, but the primer is close enough to the firing pin hole to be struck, atleast on the edge, allowing the gun to fire. What can happen is that, due to misalignment of the cylinder with the barrel, the bullet can be shaved as it tries to enter the forcing cone, resulting in a piece of the bullet being sent perpendicular to the line of the bore. If you happen to be standing there, you can be hit with a little piece that can penetrate the skin. This happened to me. They dug a little piece out of my right hand.

Not sure if it was OOB, but I saw the results of an M1 carbine that fired before the round fully chambered. The guy's face was soaked with blood from the unburned powder that flew out of the broken case head.
Had a student shooting blazer ammo at my range qualification a few years back and I commented on the cheap ammo that its great for practice but to buy and use premium ammo while carrying.but the primer is close enough to the firing pin hole to be struck, at least on the edge,
A couple weeks later he brought me several rounds that miss-fired and stated that he got the picture.
Upon a quick look at the miss-fired cartridges the problem was obvious. The revolver was out of time because the firing pin strikes were all way off center and the Berdan primers and the very small anvil integral to the cartridge case was missed and therefore didn't fire.
The revolver was inspected and there was a buildup of pocket lint causing an out of time condition. I also made a statement that I would rather have some
spit lead in a self defense encounter than a miss-fire.
Back when I 1st posted about this I was questioned by one very esteemed senior member that doughted this could happen or at least that is the way I took the comment, however it did happen just this way.
