With North American Arms and their
selection of .22 Magnum mini-revolvers fresh on my mind, I thought it might be
helpful to talk a bit about ammo choices. What follows is a run-down of some
popular ammo selections available in this chambering, as well as some newer options. .22 Magnum ammo is truly
varied in selection, running the gamut of high-velocity varmint and small
game rounds, to the newer, purpose-built defense loads expressly tailored for use in
short-barreled weapons such as NAA minis. What’s out there and what performs best
for defensive purposes? In the future, I’ll be bringing you detailed
information about actual, measured performance of some of these rounds, in
an effort to shed light on how you can select the best round for your intended
purposes. For now, here is a summary of what’s available.
Basic
offerings:
We’ll
start with the typical, classic .22 Magnum rounds. These rounds were originally
designed for taking varmints and small game. What you’ll find here is that
there are two basic avenues of delivering kinetic energy to the target—driving
lighter bullets at very high velocities, or driving heavier bullets at slower
velocities. All things being equal, both methods are interchangeable ways of achieving the same
goal of translating mass and velocity into energy. Bullet design plays a part
as well, and the classic 9mm versus .45 ACP debate comes to mind. The truth is
in the ft/lbs, as I’ll share later in more detailed tests. For now, here are some of
the rounds available today:
CCI
Maxi-Mag
40 grain JHP @ 1875 fps (rifle) |
Perhaps
the quintessential .22 Magnum round, CCI Maxi-Mag pushes an average-weight, 40
grain jacketed hollow point bullet at an advertised 1875 feet per second (fps)
from a rifle barrel. This is a common and popular round that you can find just about
anywhere, and CCI is renowned for its production of high-quality, reliable and
accurate rimfire ammunition.
Federal
Premium
30 grain JHP @ 2200 fps (rifle) |
This Federal Premium .22 Magnum load
falls into the hyper-velocity category, pushing a lighter, 30 grain jacketed
hollow point bullet at 2200 fps from a rifle barrel. Comparable to
offerings such as CCI’s Maxi-Mag HP+V and other similar varmint rounds, this variety of ammo
delivers higher speeds at the expense of bullet weight.
Federal
Game-Shok
50 grain JHP @ 1530 fps (rifle) |
Weighing in at a relatively hefty 50
grains, Federal Game-Shok was the heaviest .22 Magnum load I could find at the
time of this writing. Advertised to deliver a muzzle velocity of 1530 feet per
second from a rifle, Game-Shock sacrifices a modicum of speed in order to push its heavier 50 grain jacketed hollow point.
Winchester
Super-X
40 grain JHP @ 1910 fps (rifle) |
Winchester Super-X is a perennial
favorite of many .22 Magnum shooters, and understandably so. With the lowest
price point of all the ammo listed here, yet known as a solid all-around performer,
Super-X is indeed a very popular choice for many .22 Magnum applications. It
has also established a very good record on several mini-revolver fan and forum site,
where shooters have tested it against a variety of other .22 Magnum loads. Super-X is
advertised to push its 40 grain jacketed hollow point at a slightly
faster-than-average 1910 fps from a rifle barrel.
Defensive
loads:
Now we enter into the newer realm of
purpose-built self-defense .22 Magnum ammo. Unlike typical .22 Magnum rounds
which were originally designed for hunting varmints and small game, these
rounds are specifically designed for use against targets of the two-legged,
threatening-your-life variety. These rounds also list velocity—but out of a
handgun barrel, as opposed to a rifle. With the growing popularity of smaller
caliber weapons for concealed carry, at the time of this writing, three major
manufacturers are now producing rounds expressly catered to the self-defense
market. Whereas the .22 Magnum round and self-defense might have once seemed
like mutually exclusive concepts, these newer rounds are raising the bar for this
chambering’s performance. Some even claim to match or exceed the performance of
popular centerfire cartridges such as .380 ACP!
Here are the three lone varieties of this specialized ammo that were
available at the time of this writing:
Hornady
Critical Defense
45 grain FTX @ 1000 fps (handgun) |
Hornady’s new Critical Defense 22 WMR
utilizes a specialized 45 grain “FTX” bullet. It is technically a modified jacketed hollow point with a polymer tip, the purpose of which is to ensure
proper expansion and penetration through clothing, etc. Thus, this round is
designed to expand reliably, penetrating to an effective
depth while not clogging with material. Hornady advertises that this round performs on par with .380 ACP, delivering
a 1000 fps muzzle velocity out of a 1.875” handgun barrel. At 45 grains, it is
the heaviest of the three dedicated self-defense rounds available at the
present time.
Speer
Gold Dot Short Barrel Personal Protection
40 grain GDHP @ 1050 fps (handgun) |
Speer Gold Dot is a well-known,
classic choice for self-defense ammunition in centerfire chamberings. In fact,
many law enforcement agencies have adopted this line of ammunition for its
dependable performance. Teaming up with the rimfire gurus at CCI, Speer is now
producing a 40 grain, .22 Magnum version of their famed Gold Dot hollow point.
This new offering is also specifically optimized for use in short barrels, with an
advertised 1050 fps from a 1.9” handgun barrel.
Winchester
PDX1 Defender
40 grain JHP @ 1295 fps (handgun) |
Rounding out the dedicated .22 Magnum self-defense
rounds available at the time of this writing is Winchester’s new PDX1 22
Defender. PDX1 is Winchester’s newest line of self-defense ammo, and
this is their first rimfire offering within the line. A bit of confusion
surrounds this ammo, with various sellers listing both a 45 and a 40 grain
bullet. In truth, even a few of my suppliers and distributors are listing
conflicting data, but rest assured—it is a 40 grain, jacketed hollow point. Winchester
advertises 1295 fps for the velocity, though a barrel length is not listed. One
might assume anything from a 2-4” barrel, based on the average performance of.22 Magnum in a
rifle barrel.
Coming
soon…
Will the dedicated self-defense rounds really live up to their claims? Does regular hunting ammo perform as just well as the new kids on the block? Is there a best choice for concealed carry? Coming
up next time, I’ll share test results for all of the rounds listed above.
We’ll take a closer look at what you can really expect to get out of these
rounds, specifically out of a short-barreled weapon. Enter your e-mail
