22 WMR vs 22 Mag: A Comprehensive Comparison for Informed Shooters
The .22 Winchester Magnum Rimfire (22 WMR), often referred to as the 22 Mag, and the .22 Long Rifle (22 LR) are two popular rimfire cartridges favored by shooters for various applications, from plinking and target practice to small game hunting and pest control. While both share a .22 caliber bullet, they differ significantly in performance, cost, and intended use. Understanding these differences is crucial for selecting the appropriate cartridge for your specific needs. This article provides a detailed 22 WMR vs 22 Mag comparison, exploring their ballistic performance, accuracy, applications, and cost considerations to help you make an informed decision.
A Brief History of the .22 WMR and .22 LR
Before diving into the comparison, let’s briefly examine the history of these two cartridges.
The .22 Long Rifle (22 LR) was introduced in 1887 and quickly became one of the most popular cartridges in the world due to its low cost, light recoil, and versatility. It’s a staple for recreational shooting, training new shooters, and small game hunting.
The .22 Winchester Magnum Rimfire (22 WMR), or 22 Mag, arrived much later, in 1959. Winchester designed it to offer significantly more power and a flatter trajectory than the 22 LR, making it a more effective option for varmint hunting and longer-range shooting. The 22 WMR filled a gap between the 22 LR and centerfire cartridges like the .22 Hornet.
Ballistic Performance: 22 WMR vs 22 LR
The most significant difference between the 22 WMR and 22 LR lies in their ballistic performance. The 22 WMR boasts a higher velocity, flatter trajectory, and greater energy than the 22 LR.
Velocity
Typically, a 40-grain 22 LR bullet achieves a muzzle velocity of around 1,200 to 1,300 feet per second (fps) from a rifle barrel. In contrast, a 40-grain 22 WMR bullet can reach muzzle velocities of 1,800 to 2,000 fps. This higher velocity translates to a flatter trajectory and increased energy downrange.
Energy
The increased velocity of the 22 WMR results in significantly higher energy. A 40-grain 22 LR bullet typically generates around 140 foot-pounds of energy at the muzzle, while a 40-grain 22 WMR bullet can produce upwards of 320 foot-pounds of energy. This extra energy makes the 22 WMR more effective for hunting larger varmints and delivering more decisive kills.
Trajectory
The flatter trajectory of the 22 WMR is a significant advantage for longer-range shooting. With a 100-yard zero, a 22 LR bullet will drop significantly more than a 22 WMR bullet at 150 yards. This means you need to compensate more for bullet drop with the 22 LR, making the 22 WMR easier to use for accurate shots at extended ranges.
Accuracy: Which Cartridge is More Precise?
Accuracy is a crucial factor for any shooter. While both cartridges can be accurate, several factors influence their precision. Generally, the inherent accuracy potential of the 22 WMR is slightly higher due to its more consistent manufacturing and higher velocities. However, the quality of the firearm, the shooter’s skill, and the ammunition used play significant roles.
The 22 LR has a very large following and thus a huge range of ammunition choices, from cheap bulk ammo to match grade ammo. Some match grade 22 LR ammo can be incredibly accurate in the right rifle. The 22 WMR, while having fewer match options, still offers excellent accuracy with premium ammunition.
Applications: Where Each Cartridge Excels
The 22 LR and 22 WMR are suited for different applications due to their varying performance characteristics.
.22 Long Rifle (22 LR)
- Target Shooting and Plinking: The 22 LR is ideal for recreational shooting and target practice due to its low cost and light recoil.
- Training New Shooters: The mild recoil and manageable noise of the 22 LR make it an excellent choice for introducing new shooters to firearms.
- Small Game Hunting: The 22 LR is effective for hunting small game like squirrels, rabbits, and other small animals at close ranges.
- Pest Control: The 22 LR can be used for controlling pests like rats, mice, and other small vermin.
.22 Winchester Magnum Rimfire (22 WMR)
- Varmint Hunting: The 22 WMR is well-suited for hunting varmints like groundhogs, prairie dogs, and coyotes at longer ranges.
- Small Game Hunting at Longer Ranges: The 22 WMR provides a flatter trajectory and more energy than the 22 LR, making it a better choice for hunting small game at extended distances.
- Self-Defense: While not ideal, the 22 WMR can be used for self-defense in situations where a larger caliber firearm is not available or practical. Its higher velocity and energy offer greater stopping power than the 22 LR.
Firearms Chambered for .22 LR and .22 WMR
Both the 22 LR and 22 WMR are chambered in a wide variety of firearms, including rifles and handguns.
.22 Long Rifle (22 LR) Firearms
- Rifles: Bolt-action, semi-automatic, and lever-action rifles are commonly chambered in 22 LR. Popular models include the Ruger 10/22, Marlin Model 60, and Savage Mark II.
- Handguns: Semi-automatic pistols and revolvers are available in 22 LR. Popular choices include the Ruger Mark IV, Browning Buck Mark, and Smith & Wesson Model 617.
.22 Winchester Magnum Rimfire (22 WMR) Firearms
- Rifles: Bolt-action and semi-automatic rifles are available in 22 WMR. Popular models include the Savage A22 Magnum, CZ 457, and Marlin XT-22M.
- Handguns: Revolvers and a few semi-automatic pistols are chambered in 22 WMR. Popular options include the Smith & Wesson Model 351PD, Ruger Single-Six, and Kel-Tec PMR-30.
Cost Considerations: Ammunition and Firearms
Cost is an important factor to consider when choosing between the 22 LR and 22 WMR. The 22 LR is significantly less expensive than the 22 WMR.
Ammunition Costs
22 LR ammunition is generally much cheaper than 22 WMR ammunition. You can often find bulk packs of 22 LR for a fraction of the cost of 22 WMR. This makes the 22 LR a more economical choice for high-volume shooting and practice.
Firearm Costs
Firearms chambered in 22 LR are typically less expensive than those chambered in 22 WMR. This is due to the simpler design and lower operating pressures of 22 LR firearms.
Recoil and Noise: Which is More Manageable?
Recoil and noise are important considerations, especially for new shooters or those sensitive to loud noises. The 22 LR has significantly less recoil and noise than the 22 WMR.
Recoil
The 22 LR has very little recoil, making it comfortable to shoot for extended periods. The 22 WMR has more noticeable recoil, but it is still manageable for most shooters. However, the increased recoil can be a factor for smaller individuals or those with recoil sensitivity.
Noise
The 22 LR is quieter than the 22 WMR. This can be an advantage in situations where noise is a concern, such as in urban areas or when hunting in areas with noise restrictions. The 22 WMR’s louder report can be disruptive and may require the use of hearing protection.
