Some notes relating to the above:
During the 60's and 70's when I was a diving fanatic, I made
about half dozen 12 gage powerheads for killing big fish. Even
made one in .357 which still resides in my desk. All were of
slightly different designs but all worked very well. All were
"fire on impact" and they had the effect of a shotgun barrel
pressed up against the target - never lost a fish.
In those days one diver, an ex-frogman, was renown for his taking
of great whites that were longer than boat from which he dived.
His picture, taken at the instant of powerhead impact on a great
white's head was a cover of Life Magazine. The shark's head was
about the size of the diver's body and the gaseous discharge
could be seen emerging from the bottom of the shark's head.
After that I had no doubts about the powerhead's ability to take
500 pound jewfish.
I have fired boxes of 12 guage shotgun shells underwater in
powerheads of my own design. This is also true of .357 magnums
in experimental powerheads. The effect is a very muffled whump
that could in no way impair anyone's hearing. This is true even
when shooting into a small cave where the sound was reflected
directly back at me. In that case sometimes my mask was pushed
back against my face by the shock wave, but it was in no way
uncomfortable. It's a great way to kill a grouper weighing 50 to
several hundred pounds if one is a meat hunter as I was during
I have stunned grouper in small caves by shooting against the
cave wall next to the fish when it was too cramped to hit the
fish directly. Usually the fish recovered in 2-3 minutes or so
but that was long enough to get him into the boat if I didn't
Forty to fifty pound grouper were common in the Boca Raton,
Flodida area in 1964-67 and one fed us for a week. Really large
ones were around on occasion but they would not fit into our
refrigerator freezer and had more worms than the smaller ones.
My powerheads were only for scuba fishing - I have yet to fire
one above water. When I went back to school, we had two kids and
were dirt poor. Lobster and fish were our principle food for 3
years altho I am a beef eater (only dream of venison).
I tell anyone that is afraid of sharks or barricuda to stay out
of the ocean. Their speed and destructive power is beyond
description and a power head is absolutely worthless as
protection. If a shark wants you, you are his, believe me. I have
seen fish hit by barricuda cut comletely in two in such a flash
that only after it was all over did I realize what had happened.
I have had a stringer of fish taken from friends by a shark with such
blitzkrieg that it is impossible to believe. Fortunately, shark
seldom bother divers so, as in all hazardous activities, odds are
greatly in your favor.
I was president of a dive club for several years and taught SCUBA
for the YMCA in the 60's. Also I dived for the Navy in my
capacity as an ocean engineer for many years.
# Were the shotgun shells blanks?
Mine were regular shotloads sealed at end and primer with a boat
They were all impact actuated - simple in design but too
difficult to describe without drawings. My first was made from
pipe and pipe caps. Barrels were about 1/8" longer than the 12
gage shell. All had rudimentary safeties. I used fiberglass
shafts with no problems. A couple fatigued after much use but
caused no harm. Felt recoil was virtually non-existant.
Several years ago one of the gun magazines ran an article about
firing .45 semi-autos underwater (swimming pool). All
functioned just as they did in air with no modifications and they
found that the bullets traveled considerably farther in the water than
they did when fired from the surface where they had to penetrate
the air-water interface.

Actually no. Both times I've fired rounds underwater, I was
surprised at the low level of concussion. The first was an old junker
.32 revolver (yea, just 'cuz I wanted to know) and the second was a
bang stick of a diver friend of mine punched into an old tire. A bang stick
is an anti-shark weapon that consists of a shotgun shell on the end of
a stick. You jab your target and it goes bang.
I started out with the .32 just held underwater and my hand in a heavy
leather glove, just in case the cylinder burst. Noting nothing unusual,
next round with me standing in the water but with my head above the
surface. Nothing interesting. Last round with head underwater and with
earplugs in (swimmer's ear, not sound protection). Still nothing
unusual. Just a thunk, kinda like a miniture M-80 in the water.
Oh yeah, the .32 bullet just kinda dribbled out a few yards and fell
to the bottom of the pool. Gee I hope my ex-neighboors don't read this :-)
