The 5.7x28mm cartridge was developed by FN Herstal in the late 1980s and early 1990s. It was designed to be a high-velocity, low-recoil cartridge suitable for use in compact personal defense weapons (PDWs) and handguns.
|Parent case||FN 5.6x28mm|
|Bullet diameter||0.224 in |
|Neck diameter||0.251 in |
|Base diameter||0.313 in |
|Case length||1.138 in |
|Overall length||1.594 in |
|Case capacity||13.9 grains|
|Max pressure (SAAMI)||50,040 psi |
The 5.7x28mm is known for its high penetration and flat trajectory, making it a popular choice for law enforcement and military applications.
The most popular firearm chambered in 5.7 are FN 57 and FN P90
Popular 5.7x28 variations are:
- SS190: This is the original hardened steel penetrator round developed for the Five-seveN pistol and P90 submachine gun
- SS192: This is a hollow-point round that was designed for use in the civilian market, particularly for personal defense
- SS195LF: This is a lead-free hollow-point round that was also designed for the civilian market, with reduced penetration for increased safety.
- SS196SR: This is a sporting round designed for use in competitions and range.
- SS197SR: This is another sporting round, designed for use in competitions and hunting small game.
- SB193 subsonic: This is a subsonic round designed for use with a suppressor, offering reduced noise and recoil.
The 22 Hornet has been around since the 1930s and it was embraced and launched by Winchester. It was designed by Townsend Whelen, and it's still a popular round being produced.
Hornet was loaded with .223" caliber bullets. As commercial rifle production progressed, the groove diameters shifted from .223" to .224". Today, Hornet projectiles continue to be available in both .223" and .224" calibers.
|Parent case||.22 WCF|
|Bullet diameter||0.224 in|
|Neck diameter||0.243 in|
|Base diameter||0.298 in|
|Case length||1.403 in|
|Overall length||1.723 in|
|Case capacity||0.129 in³|
|Max pressure (SAAMI)||44,000 psi|
The Hornet quickly garnered widespread acclaim across the globe as an exceptional varmint shooting round.
In countries like Australia and New Zealand, the Hornet was not only employed for hunting small game but also served as a training round for cadets during the era of mandatory military training.
The 40 grain 5.7x28mm bullet typically has a muzzle velocity of 2,300 to 2,800 feet per second (fps), depending on the bullet weight and specific load.
In comparison, a 45 grain soft point 22 Hornet bullet offers a muzzle velocity of 2,200 to 2700 fps with about 500 - 700 ft lb of energy. (Between muzzle velocity and at about 100 yards)
It's worth noting that the 22 Hornet's muzzle velocity is significantly higher than that of the 22 WMR and 17 HMR, making it a more powerful option.
5.7 X 28
The 5.7x28mm cartridge bullet weight selection range from 28 to 90 grains. While the most popular sporting round is 40 grain.
The ballistic coefficient (BC) is a measurement of how well the bullet resists wind and air resistance. In English, it's how aerodynamic the bullet is. The higher the BC, the better because it resists wind drift better.
Typically, heavier bullets have a higher ballistic coefficient. There are rare instances when the smaller, more aerodynamic bullet has a higher BC. Obviously, the ballistic coefficient will vary from bullet to bullet, but on average, to put things into perspective, a 5.56 bullet has a BC of 0.29, and the 5.7 has an average BC of 0.197.
As we expected, the 5.56 NATO continues to outperform the 5.7.
The 22 Hornet also has a wider range of bullet weights, from 35 to 55 grains.
The 22 Hornet has a ballistic coefficient of 0.109 and 0.202 for the 35 gr and 45 gr bullets, respectively.
The sectional density of the 22 Hornet will be right around 0.100.
Heavier bullets generally offer better downrange performance, particularly for hunting applications.
The energy delivered by a cartridge is an important factor when considering its effectiveness for hunting or self-defense. The standard SS196SR 40 grain 5.7x28mm cartridge offers muzzle energy between 300 and 340 foot-pounds (ft-lbs) when shooting out of a 10.6 inch barrel P90. The bullet drops closer to about 220 ft lb of energy when shooting out of a FN 57 or Ruger 57 pistol.
In contrast, the 22 Hornet boasts muzzle energies from 600 to 730 ft-lbs. This higher energy makes the 22 Hornet much more powerful than the 22 WMR and 17 HMR.
Hunting Applications: 5.7x28 vs 22 Hornet
When it comes to hunting, both the 5.7x28mm and the 22 Hornet have their merits. Let's take a closer look at how each cartridge performs in this context.
SS197SR 5.7x28mm for Hunting
The 5.7x28mm is primarily designed for self-defense and military applications, but SS197SR round is for hunting small game and varmints.
Its high-velocity, flat trajectory, and low recoil make it an appealing choice for new and experienced hunters alike.
However, its relatively low energy and lighter bullet weights limit its effectiveness when hunting larger game or at longer ranges.
22 Hornet for Hunting
The 22 Hornet, with its higher energy and wider range of bullet weights, is a more versatile option for hunting. It's particularly effective for varmint hunting, such as coyotes, foxes, and groundhogs, as well as smaller game like squirrels and rabbits.
Its effective range extends to approximately 150 yards. When used for chest shots on medium-sized game weighing less than 40kg (88lb), the projectiles generally penetrate vital organs but tend to become lodged in the offside ribs, which for more ethical, one-shot kills.
Although the Hornet is significantly underpowered for universal use on medium-sized deer species, it has been effectively employed for head and neck shots on such game at moderate distances.
For young shooters who are new to centerfire cartridges and possess an older .22 Hornet rifle, this cartridge serves as an excellent training round, perfectly suited for small game hunting and range shooting.
Ammo Availability & Cost
22 Hornet is much more expensive, a single round goes about $2 - $3.5
5.7x28 is significantly cheaper at around $0.6 - $1.4 per round.
