BoreSight Device left in rifle...?

Recommended Posts

It is for real. I saw the article and those same photos about a year ago. Don't recall exactly where and when it happened.

Edited to add: When I was a kid I was with my old man once day when he visited a local gunsmith. He was discussing reloading with the gunsmith, and the guy warned him not to experiment with powder charges, but to always go by the book. My old man assured him he wouldn't experiment with overcharging, but might try lighter loads. The gunsmith exploded:

"That is more dangerous that heavy loads! See?"

With that he produced a high-powered bolt-action rifle. A strip of the receiver was peeled back at a 90-degree angle. It was the result a too-light reload causing a round to get stuck in the barrel. The next round blew the receiver open. The shooter went to the hospital with a face full of brass.

It's a good reason to check you bore occaisionally. It's easy to get mud or dirt in your bore and a blown up gun could be the result. I often put a piece of "light" tape over my muzzle prior to going out hunting. The air pressure ahead of the bullet will push a hole through it before the bullet even reaches the tape. I've shot many a big buck this way. It has no affect on accuracy.

I've heard of people loading a cartridge with no powder. The bullet may be pushed part way down the barrel by the primer going off. The next round would blow the gun up, if the first bullet is in there.

Some people slip a 20 guage shell into the chamber of a 12 guage. That too is asking for a blown up gun.

I once loaded some rounds with the wrong powder. The gun didn't blow up, but I got a face full of hot gases and could have ruined one of my pet rifles. I also didn't have glasses on, so I was lucky not to mess my eyes up.

So, there's a lot of stupid ways to blow up a gun. Forgetting a bore sighting tool is one I haven't thought of....

Omigod, that reminds me a a funny story I got from a local when I worked in TX. A wife came home early to find a strange car in the drive. She entered quietly and realized her husband was in the bedroom with another woman. Enraged, she went to his gun cabinet, pulled out a double-barrel shotgun, loaded it, and burst into the bedroom. As the couple cowered in the bed, begging for their lives, she lowered the muzzle to point it at him...and the two shells slid out of the barrel and bounced off his chest.:D:D:D

Not shure if this is true, but it could happen....



This ought to go to Mythbusters.

A couple of years back they tried a lot of things to get the "banana peel" effect and concluded it couldn't be done.

Already googled for that. Found this ("plausible"): http://mythbustersresults.com/episode74

The finger in the bbl episode was not even close to being the same as what we are discussing.

A squib could have resulted in death or serious injury if it were near the chamer and had another round fired afterwards.

A friend of mine had a damascus bbl shotgun that completely peeled due to using a modern cartrdge.

The shotgun was an antique and was totally ruined.

John Rich did a good job of describing another way that too light of a load can blow up a gun.....Rifle loads use slow burning powders. When the primer ignites the powder it starts burning from one end of the case to the other. Most powders almost completely fill the case. If for some reason you have a really light load (with the case only partially full of powder) the primer can ignite all the powder at once. This can cause much more pressure than your rifle chamber is made to withstand. So, this is still another way to blow up a good rifle and endanger your life!

I usually weigh each of my loads after pouring them out of my powder measure. I'm a control freak when it comes to reloading and that means better accuracy. It can also mean safety.

If you pour a load directly out of a powder measure into the case, you might end up with a case only partially full of powder. This sometimes happens if you use grain like powder. I've never tried the newer shaped (ball shaped powder). They probably come out of a powder measure better.

If you do use a powder measure, it might be good to get in the habit of looking in each case, to see if there's enough powder in there. IMR 4831 powder jams up in my RCBS powder measure sometimes. It could result in the partial filling of a case...

I'm given to understand that there's buffer material that can be used to fill the case in the event of a light powder charge - that would keep the powder charge back against the prime and prevent a detonation, wouldn't it?

In regards to the OP - I remember seeing pics of an OCMP rifle that got all torn up after a squib round - wasn't pretty!!

I tend to agree with them. The rather nice symmetry in this current example in 4 pieces just doesn't seem believable.

My reloading books recommended tufts of cotton pulled from cotton balls to do that.

Um - y'all *do* realize that button rifling creates stress patterns in the barrel, right? Not to mention that, as listed above, a round where the powder train burns all at once instead of sequentially could spike the pressure in the barrel WELL above the failure limit.

Lastly - Mythbusters (if my info is correct) *welded* a plug into the muzzle - that would actually make it LESS likely for a 'banana peel' failure to happen, since it would actually strengthen the barrel at the muzzle.

Oh, there is no doubt of that. It's just how do you get such an elegant failure, and what forces it to unfurl like that? I'd expect it to bulge outward before the end, not have the ends curls out.

If button rifling creates stress patterns in the barrel, these stress patterns would presumably follow the rifling in a spiral. Should it not then stand to reason that the failure path(s) *also* follow the rifling, instead of following very straight lines?

When a threaded fastener fails, especially with cut threads (as opposed to rolled threads), it usually fails at the root of the thread, and the fracture surface is most often an inclined plane, aligning with the thread.

It looks fake.


.............................................................
I haven't seen enough blown barrels to make a judgment on this. I tend to think it's real though. Why would anyone want to fake something like this?....



because it looks cool
because Mythbusters tried to make it happen
because they watched bugs bunny their whole life?

absolutely can happen and I have seen it first hand, both a 30-30 rifle and a shotgun.

even a few drops of water in a barrel could cause a barrel to crack. shotguns come apart easily since the barrels are so thin.

rifles are tougher to break, sometimes the barrel fails - but in a lot of older weapons, the bolt would fail instead, usually firing shrapnel in and about your face/head.

But they still fail - it's just a piece of steel with thousands of PSI pressure in it. go stuff your 30-06 with mud and pull the trigger - go ahead....I dare you....
