How and why Guns explode.

[gunbugs]

I've got a box full of this blown up stuff. I've accumulated it over the years when I worked at a full time gunshop, and at my own 'smithing business. The AMT slide is a 45 win mag. The owner thought he had Win 296 in the powder hopper...He had 231 in it instead. Probably about 4 times as much powder as would have been safe. The S&W 19 357 mag was a load of Unique. He didn't have his glasses on, and didn't see he had the "10 ' block over a notch, so he threw 15.5 grains, instead of 5.5 grains, a triple load. Took the top of the gun off. The 1911 barrel was a stuck bullet, with another one fired on top of it. The Ruger barrel is the same story.http://forum.lugerforum.com/attachmh...1&d=1624074634

I have read that the German MP5 barrels were designed to survive squib loads, where a bullet is stuck in the barrel and hit by another. Squib loads are a problem with full auto's because if there is enough pressure from the squib to work the action and feed a new round, there is no pause for you to recognize the squib shot and not send the next bullet down the barrel. I personally experienced this with an MP5. The barrel swelled just behind the front sight post and actually shot out the squib with the following round. The MP5 continued to function for numerous rounds after that, with no change of point of impact and no burst barrel! Good old German engineering!

The human error is always there, but in the last twenty + years I've been reloading literally thousands and thousands rounds of different calibers ( 9X21IMI .45ACP 357MAG 38SPL 308W 8X57JS) and although I've always considered myself a bit of an absent minded person, I've never had an issue. Have I been lucky? Maybe I've been, in any case I've always concentrated a lot on what I was doing.

During a course here I was shown a picture of a MP5 barrel, with 6 bullets stuck into each other, at which point the barrel said enough and swelled up.

my issue with this thread content is as follows----
when we are on the line at a commercial or private shooting facility, who is on the table on either side of you..?
we very likely don't know...
we don't know his weapons, ammunition, skill level or general information of his attitude about the seriousness of maintaining his equipment....
if one of these events occurs in your near vicinity, you will probably be affected...
how do we protect ourselves from the other shooter....??

I love tomaustin's thoughtful post above ... food for thought for us all ... Thanks Tom

As well Mark Serbu has added another YouTube post regarding Scott's mishap with Slap rounds ... an excellent summation of the destruction that occurred to one of his RN-50 rifle's.

You can certainly stick a bullet in a barrel, and fire another on top of it, and get away with it. But you will most assuredly want a new barrel after that, because it will bulge the barrel where the first bullet stuck. The first is a Dan Wesson 357 barrel, 4 bullets stuck near the muzzle. Next is a S&W M&P Model 10 38spl barrel, all 6 in there, with the first one almost out of the muzzle. Last, a 1911 45acp barrel with a nice bulge. That will usually stick the slide partially to the rear when the barrel bushing comes up tight against the bulge.http://forum.lugerforum.com/attachme...1&d=1624169208

Scott re-lives that near fatal day of April 9th 2021.

I have lots to say here but I will save it for later ... commenting on this video now would spoil it for others ... IMO a must watch ... lots of good lessons here guys. ENJOY
