Which cartridge has the best flat trajectory for coyote hunting?

Flat-Shooting Varmint Cartridges

When it comes to coyote hunting, a flat-shooting cartridge is essential for long-range shots. The .223 Remington and .243 Winchester cartridges stand out in this regard. The .223 Remington, with its 1:7 twist and 55-grain bullet, can maintain a flat trajectory out to 400 yards, while the .243 Winchester, with a 1:7.7 twist and 100-grain bullet, can maintain a flat trajectory out to 500 yards.

Ballistic Coefficients and Bullet Weights

The ballistic coefficient (BC) of a bullet also plays a significant role in determining its trajectory. A higher BC indicates a heavier, more aerodynamic bullet that will maintain its velocity and accuracy over longer distances. For example, the 80-grain Hornady V-MAX bullet has a BC of 0.255, while the 100-grain Nosler Ballistic Tip bullet has a BC of 0.495. The heavier bullet will maintain a flatter trajectory and hit its target more accurately at longer ranges.

Rifle and Scope Selection

To take full advantage of these flat-shooting cartridges, it’s essential to select a rifle and scope that can deliver consistent accuracy and a clear sight picture. A lightweight rifle with a good trigger and a high-quality scope with a variable power setting will help you make accurate shots at longer ranges. A scope with a 3-9x or 4-12x magnification setting will provide the flexibility you need to make shots from 100 to 500 yards or more.
