I've been lurking at many forums for a many weeks now, and I almost never see anyone mentioning times when it comes to shooting? Now, practically everyone knows that for normal times, anyway, justifiable civilian self defense happens at very close ranges, 20 ft and less. It's also commonly known that a fast man can charge,stab or club you in 2.0 seconds or less from 20 feet away (assuming a standing start). Therefore, it is unreasonable to just presume that you are going to have more than 2 seconds, total, to do your thing when attacked, correct? If he has a gun,it is reasonable to assume that you will have even less time, before you are hit by one of they enemy's bullets, true? Yet I have almost never seen any reference to how fast anyone is, either from the holster or starting with gun in hand? Ditto, in SHTF or military rifle combat, anyone can safely drop to prone in 1.0 second, so why does nearly everyone just assume that they will have an upright, stationary, frontal torso, head, arms and legs to shoot at? Yet nearly everyone does, when it comes to claiming "so and so" many yds of "effective range?" What they should be shooting at is something like a 10" diameter circle, because that's about the size of a head-on prone man as a target. That is a lot less square inches to hit than a 12"x24" torso, even without the head,neck, legs and arms, eh? 78 square inches vs 400 or so square inches. If the guy is offering a nice target, he's obviously unaware of your presence, so why would you fire at an "iffy" range? Why not let him get closer, get closer yourself, or just let him pass you by, remaining unaware of you?
