.17 Hornady Magnum Rimfire
Notes: This is a
powerful rimfire round, quite adequate for the hunting of small game at up to
medium range. It approaches the
power of the larger .22 Hornet round, and the velocity is exceptional, as is the
penetration for a round of its small size.
The .17 Hornady Magnum Rimfire also shoots very flat, and this improves
the accuracy of the round. The
round has a polymer tip (usually red in color) that causes the round to expand
greatly in soft tissue. (Hornady
calls this a “V-Max” bullet.) The
.17 Hornady Magnum Rimfire round is rapidly picking up steam, and is becoming
quite popular, with many pistols, revolvers, and rifles being designed for it.

.17 Mach 2 Rimfire
Notes: This
round was developed by Hornady on the heels of their .17 HMR cartridge, though
the .17 Mach 2 is based on a .22 Long Rifle (specifically, the .22 LR cases
designed for the Stinger round) case necked down to .17 caliber (roughly 4.5mm).
The bullet is also half the weight of the standard .22 Long Rifle round,
being only 17 grains in weight, though the propellant charge is the same as a
.22 Long Rifle round. The
combination of a light bullet and a large propellant charge (relative to the
bullet) is how the .17 Mach 2 achieves its high muzzle velocity. (Velocity falls
off quickly, however.) It has a
much flatter trajectory than the .22 LR out to about 150 meters.
The Mach 2 functions well in bolt-action rifles, though due to its high
chamber pressure, it is more difficult to make the Mach 2 function properly in a
semiautomatic weapon. (Conversion uppers are available; they replace the bolt
carrier with a heavier one, and a stronger chamber wall.
Kits that change only the barrel are also available, but the round does
not cycle as well with a simple barrel change.)
Factory-made .17
Mach 2 rounds are usually loaded with a V-Max-type or NTX bullet.
Rounds are made by Hornady, Eley, Speer, Remington, and CCI, though lots
are smaller, as the .17 Mach 2 has proved to be nowhere as popular as the .17
HMR round, and both offer similar performance.

.22 BB Cap
Notes: This
round is one of the oldest self-contained cartridges still available.
It is a “gallery” round, designed for indoor shooting at very short-range
targets. The round was made by many
companies around the world until just before World War 2, but the kind of social
shooting that spawned the .22 BB Cap went out of style at that point.
Originally, the .22 BB Cap has a round bullet in a short case and was
propelled only by the primer, but later designs has a small powder charge and a
conical bullet. Today, the round is
still occasionally used for indoor shooting, but it is also useful as a pest
control round. However, not many
firearms are still chambered for the .22 BB Cap, and RWS of Germany is the only
company still making the round.

.22 CB Cap
Notes: This
round is basically a more powerful version of the .22 BB Cap, officially first
appearing in ammunition catalogs in 1888, but probably invented before that
time. The .22 CB Cap is no more
accurate than the .22 Short and slightly less powerful, and it is useful only
for gallery shooting or pest control.
American companies stopped making the .22 CB Cap in 1942, but European
companies such as CCI occasionally make lots of them, and RWS offers it on a
regular basis and lists it in its catalogs.

.22 Long
Notes: This is
forerunner of the .22 Long Rifle round.
The .22 Long round has a smaller bullet than a .22 Long Rifle round,
similar to that of the .22 Short bullet, in a case similar to that of the .22
Long Rifle. The propellant charge is
smaller than that used in the .22 Long Rifle round, resulting in slightly less
power. Many believe that the .22
Long round has basically outlived its usefulness, and should be considered
obsolete, but many modern manufacturers still make the round.
As with the .22 Short, most bolt-action, pump-action, and lever-action
weapons chambered for .22 Long Rifle will also be able to fire the .22 Long
round, but most .22 Long Rifle semiautomatics cannot.

.22 Long Rifle
Notes: This
round was originally developed as a blackpowder cartridge in 1887.
It successfully made the jump to smokeless powder, and is now one of the
most common rounds in the world.
Though today it’s most popular use is in target matches and biathlon
competitions, it is also one of the most common varmint and small game
cartridges. Many a youngster cut
his teeth on a .22 Long Rifle-firing rifle, and we even used them for indoor
target practice in ROTC. It is,
however, unreliable at killing anything larger than a rabbit; if fired out of a
pistol-sized weapon, it is even less reliable.
Another use is with a silencer (and a very careful aim) for game culling,
and as a silenced pistol round for assassination.
The main reason that the .22 Long Rifle round (and other rimfire rounds)
can be so dangerous is that many people regard .22s as mere playthings,
forgetting that any weapon can be lethal.

.22 Extra Long
Notes:
This obsolescent round actually predates the .22 Long Rifle round, being
introduced in 1880 as a blackpowder round.
It was used in several rifles of various types, as well as some Smith &
Wesson revolvers, but has not been listed in any major ammunition catalogs since
1935. This round will not chamber
in .22 Long Rifle-firing weapons due to the length, but one can usually get .22
Short, .22 Long, or .22 Long Rifle rounds to chamber in weapons designed for the
.22 Extra Long cartridge. In power,
the .22 Extra Long, if loaded with smokeless powder, exceeds that of the .22
Long Rifle only by a tiny degree.

.22 ILARCO
Notes: The .22
ILARCO was designed in 1987 as an experimental round for the American-180
rimfire submachinegun. It is
basically a hot-loaded .22 Long Rifle round, with the heavier bullet of the .22
Winchester Magnum Rimfire round and a strengthened .22 Long Rifle case with much
more propellant. This was done to
increase the power of the American-180, which could not chamber the longer .22
Winchester Magnum Rimfire round, without having to redesign the action and
magazines. The power is almost the
same as that of the .22 Winchester Magnum Rimfire.
The .22 ILARCO round never went into large-scale production, and the sale
of the American-180 patent ensured this.
The .22 ILARCO is now a collector’s item.

.22 Short
Notes: This is
the oldest American modern-style cartridge, having been in production since
1857. The round was originally
intended for self-defense, but rapidly proved inadequate for that purpose, and
was converted to a gallery round – one that is intended for short-range target
shooting, mostly indoors. It is
still used in some Olympic and other international target competitions.
Most bolt-action, pump-action, and lever-action weapons chambered for .22
Long Rifle will also be able to fire the .22 Short round, but most .22 Long
Rifle semiautomatics cannot. The
.22 Short round is ideal for varmint or small bird hunting, but velocity drops
off rapidly after about 50 meters.

.22 Winchester Auto
Notes: This
round was used only in the Winchester M-1903 semiautomatic rifle.
It had a long life, but was finally dropped from production in the 1970s,
even though it was pronounced obsolete in 1932. It was designed at a time when
blackpowder rounds were still somewhat common, and meant to be able to be used
with nothing but the then-new smokeless powder.
It is roughly the same in power with the .22 Long Rifle, but never really
offered more than the fact that it used exclusively smokeless powder.
It is now almost impossible to find, and the rifle that fires it is a
collector’s item.

.22 Winchester Magnum Rimfire
Notes: Though
many see this round as a magnum version of the .22 Long Rifle, the .22
Winchester Magnum Rimfire round is actually based on the old .22 Winchester
Rimfire round. The .22 Winchester
Magnum Rimfire was perhaps the first of the “hyper-velocity” rimfire rounds, and
quickly became very popular. The
magnum loading means that weapons have to be specially modified or designed to
fire the cartridge.

.22 Winchester Rimfire
Notes: This (not
to be confused with the Winchester Magnum Rimfire) round was introduced in 1890
for the Winchester 1890 pump-action rifle.
Originally, Winchester used a flat-nosed bullet, and Remington used a
round-nosed bullet and called it the .22 Remington Special; later, this
distinction was lost as Winchester went to a round-nosed bullet.
It was chambered in many pump-action, single-shot, and bolt-action rifles
after its introduction, but has long been out of production, except for a
special one-time production run in 1986 by Winchester.
The Winchester Rimfire has more power than the .22 Long Rifle, but not as
much as the .22 Winchester Rimfire Magnum.
The .22 Winchester Rimfire will chamber and fire in most weapons that
will chamber the .22 Winchester Magnum Rimfire; .22 Short, Long, and Long Rifle
round will not work in a .22 Winchester Rimfire weapon, because they are
narrower than the .22 Winchester Rimfire and fit too loosely.

.44 Henry Rimfire
Notes: Though
the .44 Henry Rimfire was one of the early cartridges in firearms history (it
was developed for the original Henry rifle, and was originally a blackpowder
round), it is now considered obsolete for most purposes and is chambered only in
a few older revolvers which are no longer in production and in some newer
reproductions. It was manufactured from 1860-1934 (with later production using
modern propellants as well as blackpowder), but is now in the realm of
handloaders, and they find it tricky to load.
The .44 Henry Rimfire is not considered a particularly powerful round,
and is barely adequate for bringing down even medium game.
Large game is definitely out of its class.
It’s principal advantage is its short length, which allowed a rifle to
carry many rounds within the tubular magazines of the lever-action rifles it was
primarily chambered in during the late 1800s.
The .44-40 Winchester round is a heavily-updated and improved version of
the .44 Henry Rimfire round.
