Actually I suspect it has nothing to do with short-stroking and plenty to do with the fact that a person can and often will manipulate the action faster and harder when things get exciting in the field than they ever do on the range or in practice. Perhaps part of that has to do with the fact that we generally assume that ammo spent not trying to "hit small" is wasted ammo. In reality it makes a lot of sense to shoot as rapidly as possibly in practice just to know what can happen. It also helps develop the concept of flinging the brass and having the chamber ready for a follow-up.
I do know that a bullet loaded long for a "slight" snug kiss can result in powder disabling the "standing" (inappropriate term) ejector when the cartridge is unloaded without being fired.
