Here is the story behind it....
"You may have to watch Recoil twice. Try to follow the gun. This video is
basically a "show and tell" custom built on a Thompson Encore (fancy
version of the Thompson Contender). The Caliber... 600 Nitro Express.
that's right...an elephant gun round in a handgun. The story goes that
the guy that built it is some kind of custom gun maker, and built this
as an exhibition piece. He takes it to the range with him just to show
it off, and the big guy that shot it (in the video) had been bugging the
builder to let him shoot it. Now think about this...only until fairly
recently (early-mid '80's IIRC) the 600 Nitro Express was hands down the
biggest, nastiest, hardest hitting, and heaviest recoiling weapon you
could buy. It was designed for one simple purpose...to knock an elephant
flat on his butt. IMO, it was really built as an exhibition piece for
guys "compensating"...this cartridge is known for breaking collarbones,
arms, shoulders...of the shooter! Think about this, in the gun world
they use what is termed as a "recoil index" to kind of give prospective
buyers an idea of what a gun kicks like.
A .30-06 gets a rating of a 1.0, which for many people is about the
limit of what they can shoot multiple rounds thru comfortably. A 243 is
rated at like a .4, a .270 was like a .8, etc. The ..600 Nitro Express
is rated at 9.4...9.4 times more punishing power than a 30-06. Now watch
the video..."
