Background
This is a low pressure
munition. Unlike high pressure munitions, like a rifle, that
need very strong chambers and barrels, low pressure munitions can
use thin walled barrels. The heart of the system is the low
pressure gas generator. These gas generators are also used
for things like automobile air bags, life vest inflation, life
raft inflation, bolt cutters, grappling hooks,
radio antenna launching. This same
system is used to launch mortars.
AAI stands for Aircraft Armaments Incorporated. The origins
of the 40 mm Grenade may be in explosive bolts used in Navy
aircraft bomb racks.
In the past I had a surplus flare gun that took some impossible to
get cartridge so made up an adapter shell. It took a large
pistol primer and fired a Ping Pong ball. Some padding was
needed to keep from burning a hole in the ping pong ball, but then
it would shoot the ball over the power lines. Based on this
experience it may be possible to make a tennis ball
launcher that could be used to
put up
wire antennas based on the
high-low pressure system except using 22 rim fire blanks.
The current antenna launchers include:
Compressed gas driven tennis ball launchers. They require a
way to get the compressed gas and are more bulky than a cartridge
type device.
Bow and Arrow suffers from the problem of doing severe damage when
coming down.
Sling Shot and lead weight - has limited height capability.
I have 100+ feet tall pine trees and the sling shot at full
extension can not get that high.
Low Pressure Gas Generation
The first generation 40 mm grenade
used the very common 0.38" blank pistol cartridge mounted in the
base of the 40 mm round. When the primer is fired gas is
generated in the blank cartridge and the pressure builds up
(30,000 psi) to the point where the brass case ruptures in places
where the chamber in the 40 mm round has holes. The high
pressure gas expands into an empty space lowering the pressure
(3,000 psi) which pushes the round out the 40 mm rifled
barrel. This is called the High-Low pressure system.
The high pressure is needed to properly burn the propellant that's
commonly used in pistol rounds.
Launchers
In addition to the 40mm grenade launchers listed below there
are the spigot-type STANAG type 22mm rifle grenades (Wiki).
These are not 40mm, but rather just a different type of
grenade. Most modern military rifles have a flash hider
that's made to work with these rifle grenades (Wiki).
There are three types: those that require a blank cartridge,
those with a hole all the way through so a regular round can be
used, and those that trap a bullet.
Very Pistol (Wiki)
Named after Edward Wilson Very (Wiki)
there are two spellings Wiki shows Verey, the patent shows Very.
His cartridge looks similar to a shotgun except there's a couple
of pyrotechnic balls that ignite as soon as the cartridge is
fired and so, like a tracer round, there's light from the muzzle
until burnout after reaching maximum altitude. He patented
the signal cartridge (not a pistol) which came to be called the
Very Light.
Signal Cartridges were intended to be used like Signal Flags (Wiki)
or Morse Code (Wiki) and
Aldis lights 1867 (Wiki),
that's to send a message.
In 1846 Henry J Rogers (short bio at: Famous
Americans -Mr. Rogers published (visual signaling codes
for daytime use?).
- "Telegraph Dictionary and Seaman's Signal-Book"
(Baltimore, 1845);
- "American Semaphoric Signal Book " (1847) ;
- " American Code of Marine Signals " (1854); and,
- with Walter P. Larkins. edited "Rogers's Commercial Code
of Signals for all Nations" (1859).
In 1859 the Coston colored fires were being used.
An example is in Season
7, Episode 1, Murdoch
Ahoy, of the Murdoch Mystery series near the end
as a ship is going down. You see two red balls of light
arching up and then down.

Because it's length is too short to qualify as a shotgun I

Although it might be classified as a shotgun pistol.
Ammunition (Wiki)
There's a question about what ammo fits what.
For example the practice ammo for the Mk19 & M79 shown below
does not fit the AN-M8 flare pistol. I have a Webly &
Scott 1.5" (40mm) flare pistol on the way to help resolve this.
40 mm practice rounds 1969 M385
These rounds do not use the .38 blank
but might be using an aluminum 12 ga short blank
or just a pistol/rifle primer?
These are for the Mk 19, not the M79/M203.
See: Amron- 40mm

The M118/M195 case appears to use the .38 blank.

Ping Pong Ball Adapter
While traveling in Canada many decades ago picked up a ships port
or starboard kerosene lantern and a flare pistol from a maritime
surplus store. The flare pistol was old pitted metal with
handmade wooden grips. The flare was a standard 40mm
size. For fun a friend made an adapter to allow shooting a
ping pong ball by making the bore of the adapter 1.48" I.D.
(37.6mm) (Wiki: Ping Pong
ball 40mm) Propulsion by means of a small rifle/pistol
primer (external
web page with dimensions) (no powder) with a pocket diameter
near 0.175" I.D. The main body diameter is about 39.8mm, but
at the time I didn't know about 40mm grenades and so just made the
OD to fit the flare gun.
If the ping pong ball is used by itself the primer may blow a
hole into it, so a few disks of cardboard are needed as
packing/wadding below the ping pong ball. It will shoot the
ball over the top of power lines never to be seen again.
40mm (37mm?) antenna cartridge
This was a Vietnam era round probably used by the special forces in
conjunction with the GRC-109.
