Lucky man in many ways. Quick thinking on his self trama treatment direct pressure plugging artery and medical team action.
He said hot round. But he also had a round shot low? He could have had a detonation of the last round which would have also likely destroyed the action. Slow burn powder and undercharged case it can happens.
Thanks for the post.
combustion of a substance which is initiated suddenly and propagates extremely rapidly, giving rise to a shock wave.Compare with deflagration.
The Difference Between Deflagration and Detonationhttps://www.thoughtco.com/explosions-deflagration-versus-detonation-607316
Combustion (burning) is a process by which energy is released. Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds (slower than the speed of sound), it's a deflagration. If the explosion moves outward at supersonic speeds (faster than the speed of sound), it's a detonation.
While the action of deflagration is to push the air in front it, objects do not explode because the rate of combustion is relatively slow. Because the action of detonation is so rapid, however, detonations result in shattering or pulverizing objects in their path.
The definition of deflagration, according to the "Collins English Dictionary" is "a fire in which a flame travels rapidly, but at subsonic speed, through a gas. Deflagration is an explosion in which the speed of burning is lower than the speed of sound in the surroundings."
Everyday fire and most controlled explosions are examples of deflagration. The flame propagation velocity is less than 100 meters per second (usually much lower), and the overpressure is less than 0.5 bar. Because it is controllable, deflagration can be harnessed to do work. Examples of deflagrations include:
internal combustion engine (used in any vehicle that uses fossil fuels such as gasoline, oil, or diesel fuel)
gas stove (fueled with natural gas)
fireworks and other pyrotechnics
gunpowder in a firearm
