GP100 Story

For the believe it or don't file

In a BS session at the range yesterday, I mentioned I had brought my GP100. One of the participants then told the story of helping a friend remove the bullet protruding from the barrel and then discovering that there were 4 behind it.

No damage to the barrel or shooter.

green, why in the world would you loan your GP100 to these azzclowns?

Had a bullet stick in the barrel of my P3AT on 2 different occasions but it did not go in far enough for the slide to got into battery with the fresh round. Got rid of that box of ammo and went on with life.

umm.... i think thats a tall tale. we've all had the "pop" instead of "BANG" and probably had to punch a stuck bullet from the bore before, but 4 stuck bullets in a barrel? I'm not buying that one for a dollar

I would not touch that one withan 11 foot pole.

I've seen several revolvers with bullets stacked in the barrel. One in particular sits as a cut-away in the SF Police shooting range display case with six bullets stacked in the barrel. If I recall correctly there's a 3x5" index card underneath with handwriting on it that says, "Why we don't allow reloaded ammunition on this range."

I have a hard time believing there's no other damage. Typically when this happens the successive rounds bulge the barrel as the next bullets compress the trapped air in between.

Kaz: I didn't loan them my gun. Just a BS session. I did load the GP100 for a guy on the range after he was bragging about how good is 686 was. Did the same with my M17, it's terrible to watch a grown man drool over a hunk of metal.

Bullseye: My thought was the pressure would bulge the barrel. However, if the first round stuck then you could move the bullets down the barrel a bit. No sixth round in the gun and one was poking out of the barrel, according to the story. Seems like a bit of a stretch.

That's a stretch all right damn near to the ultimate breaking point, eh????

When this happens there's no getting them out of the barrel. I found this picture just to illustrate what I mean.

If you look closely at the last round you can see a slight bulge in the barrel at the air gap.

Is this condition caused by just by under powered rounds, or are there other factors?

Bullseye, you mentioned you had seen several revolvers with bullets stacked in their barrels, are semi-autos not as prone to stacking?

Post by **Bullseye** » Tue Feb 15, 2011 6:29 am

No, both can have stacking occur but with a semiauto pistol the slide often doesn't cycle the next round and that is a clue to the operator that something isn't right. With a revolver, the cylinder rotates and the successive bullets fire without much indication to the shooter something's amiss.

Underpowered rounds or a barrel obstruction are the main causes for this type of event. Things like case head separation can cause an obstructed barrel too, if the projectile fails to clear. It is always wise to inspect a barrel whenever an unusual even occurs just to be sure there is no possibility of an obstruction.

Thanks for explaining Bullseye. I agree that any time the shot doesn't feel right, one should check the barrel. Fortunately, a squib has never occurred to any firearm I have used, but I imagine it's only a matter of time.

Can someone please explain what case head separation is?

WOW! What a chilling cut a way picture. I'll bet that this is something that could happen to almost all of us if we were shooting timed competition events where the focus is on a win where hundred's of seconds determine winning/losing. Regards

Case head separation is where the brass casing fails and hot gasses are vented out of the chamber instead of down the barrel. It gets this name because when it happens the cartridge case head is usually blown off or nearly separated from the spent casing. This condition can come from an unsupported brass casing or by the case having a fatigue crack or other abnormality. In pistol this is bad with some damage but with rifles, the result is typically a very destructive event with the rifle receiver being severely blown apart. Typically called a "KaBoom" or "KB" buy shooter slang terms.
