Performance and Ballistics
This cartridge truly shines when it comes to the numbers. The .243 Winchester Super Short Magnum is engineered for velocity. Muzzle velocities can reach speeds that significantly exceed those of the traditional .243 Winchester, often exceeding feet per second. This elevated speed translates into a flatter trajectory, an important advantage, especially when shooting at extended ranges.
Trajectory charts paint a clear picture of the .243 WSSM’s flat-shooting nature. Bullets travel on a much straighter path compared to cartridges with lower velocities. The bullet drops less over distance, a key advantage for accurate shooting. This reduction in bullet drop makes it easier to compensate for range, especially at longer distances. This, combined with a higher ballistic coefficient, allows for greater energy transfer downrange.
The effective range of the .243 WSSM can vary depending on the bullet weight and target. However, for hunting purposes, it is an excellent choice for game like coyotes, prairie dogs, or even deer, with ethical shot distances of up to three hundred yards. The flat trajectory and high velocity also make it suitable for longer shots, provided the shooter has mastered the fundamentals of wind estimation and range estimation.
Wind Drift
Wind drift is always a consideration when shooting at long distances. The high velocity of the .243 WSSM does mitigate the effects of wind to a certain extent, but it is still a factor that must be taken into account. Knowing the wind conditions and how to adjust for them is crucial for consistently accurate shots.
Accuracy Potential
The potential for sub-MOA (Minute of Angle) groupings is a feature that places the .243 WSSM in the category of an accurate platform. Precision is not only a function of the cartridge design but also of a quality rifle, accurate reloading techniques, and a competent shooter. With a well-built rifle and a carefully crafted load, many shooters have achieved impressive results with this round, even at longer ranges.
