Hmm, never saw that. I'd have to say that if anything, the effectiveness of a shotgun is understated by RPGs.
I mean a 12 gauge shotgun is a pretty serious piece of boom stick. While everyone is quite familiar with gun diameters since caliber is a pretty straightforward measurement, gauge is rather obtuse. Your normal guns pretty must just tell you the inside barrel diameter (9mm, 45 caliber=.45 inches). Shotguns OTOH use a rather archaic system where the gauge means the number of lead balls with the diameter of the barrel which would make one pound. Thus lower numbers are bigger. Hence, about the most common shotgun gauge, 12 gauge is .727 inches or 72 caliber. Remeber a 9mm translates to about 35 caliber (roughly the same as a .357 magnum, though the bullet selection is quite different).
The guys on the web page blew the lock apart with a shotgun slug. Those are basically single bullets for shotguns. If we look at what he used on the lock (I will assume most common bullet weights):
9mm 115 grain
.45 ACP 230 grain
.44 (Remington)magnum 240 grain
.223(5.56 mm NATO) ~70 grain
.308 (7.62 mm NATO more or less) 147 grain
12 gauge shotgun (.727 inches) 437.5 grains (1 ounce).
A we can see the bullet from the shotgun is twice(roughly) as heavy as any of the pistol rounds and is probably going at least as fast as the magnum round (comparable).
If you've ever seen a shotgun slug, you'd be quite certain that you had no desire to be on the receiving end.
Though in RPGs most shotgun uses are probably assumed to be shot (buckshot I'd bet). What is buckshot? Well it's the largest shot size used in shotguns. Commonly people use 00 buckshot. This means a bunch of 33 caliber balls. The number of balls depends on the gauge of the shotgun and the length of cartridge. You can generally assume that a dozen balls is reasonable for a 12 gauge. So if you get tagged by a 12 gauge firing buckshot (at close range), it's not very different from being shot 12 times by a submachinegun.
So to anyone who thinks RPGs overstate shotguns, put the above in your pipe and smoke it.
