Do you know of any actual metrics/tests done that show this clearly?
No one probably cared to design a barrel and firing mechanism just for this experiment since maybe the late 1930s. And, I’d guess that possible someone was the US military.
Honestly, no one really cares. There’s so many variables that change slightly for each cycle of the action. Variables change more for each round, assuming typical ammo. And, there’s a lot of variables that change a helluva lot between humans. After deciding usage and the appropriate round to chamber, one starts picking their pistol based on what feels good in their hand. Those are the ones they’ll shoot most accurately with.
my physics classes were a long time ago
The hardest part by far is visualizing a graph. Force is the y axis. Time is the x axis. A line represents a changing force over time called an impulse.
Impulse 1: acts with a force of 1000 Newtons for 0.01 second
Impulse 2: acts with a force of 10 Newtons for 1 seconds
The impulse magnitude is the integral, the area under the curve of the graph of force over time. The math is easy for these situations because they’re rectangles: 10 x 1 and 1000 x 0.01.
Both impulses have the same magnitude: 10 Newton x seconds. Both impulses, applied upon a mass, can do the same amount of work. Both impulses could be the equal and opposite reactions to firing the same round if fired from different pistols.
The revolver delivers a short, violent, mess of peaks and vallies along a big peak. The modern semi auto delivers a smooth increase to a lower plateau that falls off just as smoothly. The modern semi auto takes much longer deliver the same magnitude impulse.
But, a human brain and body doesn’t care much about “much longer” when it’s still “instant”. The brain and body care about the how high the peak is and how “messy” (signal noise).
