Introducing the Contenders
On the planet of ballistics, the 5.7x28mm and the .22 WMR signify totally different approaches to efficiency. The 5.7x28mm is a centerfire cartridge, designed primarily for navy and legislation enforcement purposes. It made its debut with the FN P90 private protection weapon (PDW) and the 5-seven pistol, each developed by Fabrique Nationale (FN) of Herstal, Belgium. Its design targeted on excessive velocity and light-weight projectiles, looking for to offer wonderful penetration in a compact and controllable package deal. This makes the 5.7x28mm a definite alternative within the trendy panorama of cartridges.
The .22 WMR, however, is a rimfire cartridge, a direct descendant of the ever present .22 Lengthy Rifle.

Analyzing the Numbers: Ballistic Evaluation
Understanding the uncooked ballistic knowledge is important to a correct comparability. The rate and trajectory, the core of bullet flight, differ considerably between these two cartridges. The 5.7x28mm, because of its design, boasts an exceptionally excessive muzzle velocity. Relying on the load and barrel size, bullets can simply obtain velocities exceeding two thousand toes per second. This interprets to a flatter trajectory, which means the bullet drops much less over distance in comparison with slower rounds. A flat trajectory is essential for accuracy at prolonged ranges.
The .22 WMR, whereas sooner than a .22 Lengthy Rifle, usually displays a decrease muzzle velocity than the 5.7x28mm. Typical .22 WMR rounds obtain velocities within the vary of 1,500 to 2,000 toes per second. This distinction in velocity leads to a extra pronounced bullet drop over distance. Shooters should compensate for this drop by adjusting their sights or hold-over when taking pictures at longer ranges.
The vitality carried by a bullet, expressed in foot-pounds, is one other essential issue. The 5.7x28mm, once more attributable to its excessive velocity, delivers a better quantity of vitality on the muzzle. Whereas the exact figures fluctuate relying on the bullet weight, the 5.7x28mm usually carries greater than the .22 WMR. This larger vitality can translate into better stopping energy and, doubtlessly, enhanced penetration.
The .22 WMR, though delivering a decrease vitality stage than the 5.7x28mm, nonetheless offers a noticeable energy improve over its .22 Lengthy Rifle counterpart. The .22 WMR’s affect at its muzzle is a noticeable one.
Completely different bullet varieties play an important function in optimizing the efficiency of each cartridges. The 5.7x28mm generally makes use of full steel jacket (FMJ) bullets, designed for penetration. Nonetheless, it additionally gives jacketed hole level (JHP) choices for enhanced growth and terminal efficiency. Bullet choice is a key think about figuring out how every cartridge interacts with its meant goal.
The .22 WMR generally incorporates a vary of bullet varieties, together with FMJ, JHP, and solid-nose bullets. The number of bullet kind permits hunters and shooters to tailor their cartridge to their particular wants. The JHP bullets are designed for growth, growing the wound channel and the switch of vitality to the goal.
On the Vary and Past: Sensible Efficiency
The accuracy and efficient vary of every cartridge are vital concerns. The 5.7x28mm, with its flatter trajectory and better velocity, usually gives the potential for better accuracy at longer ranges. The spherical’s inherent accuracy mixed with correct ammunition and taking pictures abilities permit for correct hits out to a number of hundred yards, making it appropriate for goal taking pictures and sure searching purposes.
The .22 WMR, whereas able to cheap accuracy, has a extra restricted efficient vary. Its trajectory leads to vital bullet drop at longer distances, making exact shot placement tougher. Whereas the .22 WMR can definitely be used for goal taking pictures and varmint searching at reasonable ranges, its efficient vary is usually shorter than that of the 5.7x28mm.
Stopping energy, a considerably subjective time period, is one other key consideration. The 5.7x28mm, attributable to its larger velocity and vitality, has the potential for higher penetration and wounding capabilities. The design of the projectile permits for better penetration. The stopping energy of any spherical, nonetheless, relies on a lot of components.
The .22 WMR, regardless of its diminished energy in comparison with the 5.7x28mm, nonetheless gives good efficiency for the dimensions and price of its ammunition. It’s a appropriate spherical for varmint searching. The .22 WMR’s vitality switch is commonly ample for taking down small sport successfully.
For the hunter, every cartridge has its place. The 5.7x28mm can be utilized for searching small sport, similar to varmints, the place its flat trajectory and reasonable vitality could also be advantageous. Nonetheless, moral searching requires a cautious consideration of shot placement and the restrictions of the cartridge.
The .22 WMR is a well-liked alternative for small sport searching, with many shooters favoring it for rabbits, groundhogs, and different small varmints. Its mixture of accuracy, vitality, and affordability makes it well-suited for this function. Nonetheless, its comparatively restricted efficient vary and stopping energy should be thought of when selecting a goal and making a shot.
Within the realm of self-defense, the suitability of those cartridges is commonly debated. The 5.7x28mm, with its excessive velocity and potential for penetration, can provide a bonus in sure defensive conditions. Its smaller bullet diameter additionally doubtlessly reduces the chance of over-penetration, though this attribute additionally varies relying on the load.
The .22 WMR has lengthy been a staple of non-public protection. The benefit of use, low recoil, and manageable dimension make it widespread. Nonetheless, its decrease vitality ranges and diminished stopping energy can result in combined outcomes.
Availability, Value, and Comfort
The supply of firearms chambered in every cartridge performs an important function within the consumer’s determination. The 5.7x28mm has seen a rise in recognition.

The .22 WMR, with its decrease ammunition prices, is a major draw for a lot of shooters. The .22 WMR has vast availability. Many several types of firearms could be discovered on this cartridge.
The .22 WMR is considerably restricted. The .22 WMR lacks the potential stopping energy of some bigger centerfire cartridges. The vary limitations will affect the cartridge’s usefulness in some eventualities.
Making the Proper Alternative
So, which cartridge reigns supreme? The reply, as with most firearms questions, is “it relies upon.” For these prioritizing accuracy, vary, and potential penetration, the 5.7x28mm stands out as the more sensible choice, particularly in eventualities the place stopping energy is a excessive precedence. It’s the popular alternative for these prepared to put money into the ammunition and gear.
For these looking for an reasonably priced, available, and versatile cartridge for plinking, small sport searching, or goal taking pictures at reasonable ranges, the .22 WMR is a wonderful choice. Its ease of use and low value make it a sensible alternative for a variety of shooters.
In the end, one of the simplest ways to find out which cartridge is best for you is to think about your particular person wants, funds, and meant use.
