Hands on Field Training always trumps class room training.A tension pneumothorax decompression with a K-Bar... That's some really quick thinking. I wouldn't have even thought of trying that with anything other than a syringe like they taught us in our Combat Life Saver class.
I think attempting to use a K-Bar to decompress a tension pneumothorax goes a little beyond the subject of classroom versus field training. The Army's Combat Life Saver course uses very realistic medical training dummies, so it's about as hands-on as you can get without using real people or live pigs.Hands on Field Training always trumps class room training.
The "hands-on" experience I'm talking about came/comes from being in actual VERY realistic combat, with ACTUAL people.

The more appropriate way to frame it is doctrinally accepted versus improvised out of the height of necessity. Being able to improvise like that comes from pure experience garnered through trial and error. When the equipment isn't available to use the doctrinally accepted method, only experience provides the insight needed to use a seemingly inappropriate tool for the job.
"Realistic" combat or "real" combat? If it's "realistic" combat, then it's training. If it's "real" combat, then it's experience, just as I said earlier.The "hands-on" experience I'm talking about came/comes from being in actual VERY realistic combat, with ACTUAL people. Combat Engineer 70-73.
It’s hard to know what happened and we will never know. There is also the theory, at least in my mind, of transportation of the SLAP rounds. I have heard the old wives tale where ammo that has ridden around in a car for a couple year then shot blows up a gun. The theory being the bumps and vibrations break up the powder kernels increasing surface area and increasing the burn rate.So with the listed data as being lighter and faster, its safe to say the powder charge was increased which is typical in most reloading manuals, heavier less charge, lighter bullet more charge. i wonder if that is a possible clue, but the round going out the side of the barrel, is it possible the sabot twisted in the barrel causing an obstruction and overpressure failure. Interesting for sure.
But its a 50 bmg, how much more penetration do you need? Trade up to an anzio 20mm.
It was this: RN-50After watching the "explosion" at roughly the 4 min mark ( yes i fast forwarded per the guy who sent it to me) i went back and watched it in it's entirety. I was amazed at the screw on end piece and how the rear of the gun locked in place. Still not sure if this is a one and done custom or a commercially produced firearm. I think he says ( hard to fully catch it) Barrett ... does anyone know this to be true?
I saw the same Backyard Ballistics video and thought it the most credible, as well. I am no engineer but had enough calculus-based physics beaten into my head, back in the day, to appreciate the force vectors he described.I have been watching this since it was first reported. I do some forensic engineering for my employer and study why things fail. The You Tube videos that have followed the original Kentucky Ballistics video have been quite humorous. There have been several You Tubers step up to show their ignorance while trying to get views.
The best video(s) out on this (there are 2 so far) are by an Italian engineer on his channel Backyard Ballistics. He has some great content on what causes these explosions and what guns detonated by over-loads, stuck bullets and bore obstructions look like after failure.
I would not want to be the designer/seller of these guns right now. There are several thousand in shooters hands as we speak. The maker wants the gun back to study why it failed. Personally, a third party evaluation is in order.
I have my own opinion of why this thing failed. It follows the same idea Backyard Ballistics has; that pressure from a ruptured case got between the failed case head and the under-side of the threaded cap. The cap has a large surface area for the pressure to act on. A simple vent in the cap, like just about every bolt action gun made uses, would minimize the potential damage from this type failure.
