Quick Answer
A range of 200-300 yards is ideal for using a .243 to hunt coyotes, due to its flat trajectory and adequate kinetic energy at these distances.
Optimal Range for .243 Hunting
The .243 Winchester is a popular varmint cartridge known for its flat trajectory, making it suitable for hunting coyotes at moderate ranges. When hunting coyotes, a flat-shooting cartridge like the .243 can be effective at ranges up to 300 yards, but beyond this distance, the kinetic energy of the bullet may not be sufficient to ensure a quick kill.
Kinetic Energy and Wound Channels
At 200 yards, a .243 Winchester bullet with a muzzle velocity of 3,000 feet per second can retain around 1,300 foot-pounds of kinetic energy. This is sufficient to create a large wound channel and a quick kill. However, if the range exceeds 300 yards, the kinetic energy of the bullet may drop to around 600 foot-pounds, which may not be enough to ensure a clean kill.
Hunting Techniques for Coyotes
When hunting coyotes at ranges up to 300 yards, it’s essential to use a high-powered rifle scope with a magnification of 6-12x. A spotter or a shooting buddy can also be helpful in spotting the coyote and providing wind calls. It’s also crucial to aim for the coyote’s vital organs, such as the heart and lungs, to ensure a quick and humane kill.
