2. Muzzle Velocity
Muzzle velocity represents a critical differentiator in the .22 WMR versus .22 LR discussion. .22 WMR cartridges consistently exhibit significantly higher muzzle velocities compared to .22 LR cartridges. This velocity difference stems from the .22 WMR’s larger case capacity, accommodating a greater powder charge. The increased propellant volume generates higher pressures, accelerating the bullet to a greater speed upon exiting the barrel. For instance, a typical .22 WMR load might achieve muzzle velocities exceeding 1,900 feet per second (fps), while a standard .22 LR load might reach around 1,200 fps. This discrepancy in muzzle velocity directly impacts trajectory and terminal ballistics.
The higher muzzle velocity of .22 WMR translates to a flatter trajectory. This flattened trajectory reduces bullet drop over distance, increasing effective range and improving accuracy, particularly at longer ranges. In practical terms, this means a shooter can engage targets at greater distances with less need for holdover adjustments compared to .22 LR. For example, when hunting small game, the flatter trajectory of .22 WMR can prove advantageous when engaging targets beyond 50 yards. Conversely, .22 LR’s lower muzzle velocity results in a more pronounced arc, necessitating more significant adjustments for bullet drop. This ballistic difference influences cartridge selection based on intended shooting distances.
In summary, muzzle velocity serves as a key distinguishing factor between .22 WMR and .22 LR. The higher muzzle velocity of .22 WMR contributes to a flatter trajectory, increased effective range, and enhanced terminal ballistics.

For example, while a .22 LR might be considered effective for hunting small game out to approximately 75 yards, a .22 WMR can extend that range to 125 yards or more. This difference stems from the .22 WMR’s ability to deliver sufficient energy for humane kills at greater distances. Understanding effective range is crucial for ethical hunting practices and achieving desired outcomes in various shooting applications.
The discrepancy in effective range influences cartridge selection based on intended purpose. For target shooting at shorter distances, the .22 LR’s lower cost and recoil often make it a preferable choice. However, when engaging targets at longer ranges, as encountered in varmint hunting or pest control, the .22 WMR’s extended effective range becomes advantageous. Consider a scenario involving prairie dog hunting: the .22 WMR’s flatter trajectory and higher energy at longer ranges increase the probability of clean, ethical shots, whereas the .22 LR might prove inadequate beyond a certain distance. Practical considerations, such as terrain and target size, also factor into effective range calculations. Open terrain, for instance, often allows for longer shots compared to densely wooded areas.
In summary, effective range represents a key performance characteristic distinguishing .22 WMR from .22 LR. The .22 WMR’s inherently greater effective range derives from its superior ballistics. This extended range provides practical advantages in scenarios requiring engagement at longer distances, particularly in hunting or pest control applications. Conversely, .22 LR remains a viable option for shorter-range activities where its lower cost and recoil are beneficial.
