Spread the word; knowledge is power!First produced in 1930, the .22 Hornet was developed by the Springfield Armory and is to this day an excellent cartridge for hunting varmints and predators. It has even been used in the U.K. for hunting deer with great success. The cartridge has mild recoil and good accuracy, with relatively low noise levels – making this a great choice for hunting vermin in more populated areas.
The Power of the 22 HornetThe .22 Hornet is a centerfire cartridge, available with bullets weighing from 35 to 55 grains. Bullets most commonly have soft points or are produced for specific varmints like the V-Max.
Muzzle velocity ranges between 2,600 and 3,000 feet per second. Muzzle energies, as a result, vary between 700 and 850 foot pounds when fired from a rifle. The maximum effective range is 150 yards for larger vermin and predators, and as much as 200 yards for smaller varmints. Some hunters use this cartridge to shoot feral hogs, but shot placement must be precise to use the .22 Hornet for this application.
One of the big attractions of the 22 Hornet is the power – it’s a small round packing a big punch. It has a significant power advantage over the .17 HMR and the 22 WMR, and it’s also a centerfire cartridge, which makes it far easier to reload and to handload (a strong value proposition for the amateur handloader or reloading enthusiast). Until the introduction of the FN 5.7x28mm, this was the smallest commercially available 22 round on the market. It’s often said to sit between the .22 WMR and the .223 Remington in terms of power for varmint and predator rounds. Because of the velocity, energy and noise levels, it’s the perfect round for varmint and predator solutions while in more densely populated areas.
For what it’s worth, wildcatters love to wildcat the 22 Hornet into variations of their own. Prominent wildcatter Lysle Kilbourn came up with the .22 K-Hornet, a 22 Hornet with an extended case shoulder to allow for more propellant in the cartridge. Another is the 22 Ackley Improved Hornet, which comes from the mind of P.O. Ackley, one of the most famous wildcatters in the world. This is a 22 Hornet with significantly increased power that is not quite deer legal in many parts of the EU, but is completely deer legal in the United States.
The History of the 22 HornetThe precursor to the 22 Hornet is a similar round now known as the 22 Harwood Hornet to avoid confusion with the modern round. These two rounds are not compatible with one another. The original Hornet round was a necked-down .25-20 single shot loaded with black powder. The 22 Hornet as we know it was a result of experimentation in the 1920s, putting black powder into .22 WCF at the famous Springfield Armory. In 1930, Winchester picked up a wildcatted round and started making ammunition for firearms that hadn’t yet been commercially manufactured. In 1932, the first commercially produced firearms for this cartridge rolled off the lines.
The .22 Hornet became relatively famous in World War II, where it was used in the M4 by the U.S. Army Air Corps, and later in the M6 for aircrew members. After the war, the Springfield Armory produced the M6 chambered for the .22 Hornet and .410 Bore in an over-under configuration.
1933 was a game changer for the round. It was in this year that the Winchester Model 54 rifle first came off the assembly line for mainstream commercial purchase. The popularity of the cartridge exploded and it became the third-best selling round for the Winchester Model 70s during the interwar period. In Europe, the round was known as the 5.6x35mm and it mostly found a home in bolt-action and single-shot weapons.
There are three main uses for the 22 Hornet, which displays a shocking versatility for this unassuming round. The three main applications of the .22 Hornet are:
• Survival: Air crews were given 22 Hornet-based survival rifles before flying over enemy territory during the immediate period following World War II. There were three different weapons deployed to the airmen:
o ArmaLite AR-5: This weapon entered service in 1956. It was lighter and more compact than its predecessors. This was designed less for the flying fortresses of World War II and more for the cramped cockpits of Cold War-era spy planes. Another unique development of this weapon was that the entire thing could be disassembled and stored within the stock. This weapon was later developed further into the AR-7, which shot .22 Long Rifle rounds.
o M4 Survival Rifle: The purpose of the M4 Survival Rifle was to hunt wild game after an aircraft had crashed. However, they were equipped with full metal jacket 22 Hornet rounds so they could be used as defensive weapons as well.
o M6 Aircrew Survival Weapon: This existed alongside the M4 in the years between 1954 and 1970. The plan was to replace both of the weapons with the AR-5, but it never ended up happening. A couple of commercial versions of this firearm were produced: The Springfield Armory M6 Scout and the Chiappa M6 Survival Gun.
• Competition: The .22 Hornet round has become a popular choice for those in metallic silhouette shooting in the field and hunter’s pistol category.
• Hunting: The Hornet .22 has become a popular hunting round thanks to being championed by prominent survivalist Mel Tappan who has touted the almost total lack of recoil and near-perfect accuracy. He has, however, explicitly said that it is not an appropriate round for hunting deer. Turkey hunting is more where this round is going to find its niche. Jack O'Connor has likewise denounced the round as a deer hunting cartridge.
After the Second World War, the cartridge began to fall out of favor for a few reasons. One major one was that the primary American manufacturers of the round changed the bore diameter. What’s more, the .222 and .223 Remington cartridges were specifically designed to compete with and overtake this round due to their similar size and increased velocity.
Still, the round continued to exist and sell quite well despite an increasingly competitive market. It’s niche still remains in the world of varmint hunters and some competition shooters. The light recoil is an attractive prospect, particularly for young, injured or smaller shooters who find other calibers to be too powerful for them to shoot accurately.
