Kinda long, but very worth watching. To me this screams to only use known ammo.
SLAP - Saboted Light Armor Penetrators. There was a mention in a comment I saw on another site that this might have been a sabotage round meant to inflict this very type of damage to an enemy weapon. The video creator admitted it was MilSurp from some other country and that it was shooting very erratically. Another reason to know about the ammo you are shooting. In this guys video...he had commented that he had shot the weapon many..many times prior and had never had an issue. I definitely feel that this was an ammo and not a gun issue. If the threads on the insertion system had been stretched previously, it would not be able to be threaded and function properly. It is a poor design as if it does fail, the shooter will be on the BAD end of the failure. However...we as shooters don't anticipate our weapons to fail. JMHOThat's the same failure as the first Vulcan 50s. Vee form threads don't attain full strength with less than a diameter engagement and are NOT the proper design for intermittent thrust loads.
That was a dumb idea to pull the trigger on that thing.
What is a SLAP round?
And a Ruger No.1, as I discovered once, just makes you wonder why the bullet hit WAY high (at several hundred meters), as it deposits the freed primer separately from the rest of the case....85KPSI...
Loading a M98 (even a '93) to the same levels blows the floor plate off, breaks the stock, loses the extractor, blows smoke in all directions BUT backwards. A styrofoam maniquin head behind it has speckles of carbon but no rifle parts in it.
A Rem M700 gets hard to open and blows a primer.
