Is a flat trajectory more beneficial for long-range prairie dogs?

Optimal Barrel Length and Twist Rate for Flat Trajectory

When targeting long-range prairie dogs with a 257 Weatherby Mag, it’s essential to consider the barrel length and twist rate for optimal performance. A longer barrel (24-26 inches) can help stabilize the bullet and reduce wind deflection, contributing to a flatter trajectory. A slower twist rate (1:12 or 1:13.5 inches) can also help stabilize the bullet’s aerodynamics, further enhancing the flat trajectory. However, a slow twist rate may not be suitable for heavier bullets, so it’s crucial to balance the twist rate with the bullet’s weight.

Choosing the Right Ammunition for Flat Trajectory

For a 257 Weatherby Mag, choose ammunition with a flat-shooting profile, typically featuring a heavier bullet (100-120 grains) with a high ballistic coefficient (BC). A high-BC bullet will maintain its velocity and trajectory over long distances, reducing wind deflection and allowing for more accurate shots. Look for ammunition with a muzzle velocity of around 3,000-3,200 feet per second (fps), which will provide a flatter trajectory and increased range.

Hunting Techniques for Long-Range Prairie Dogs

When hunting long-range prairie dogs, use a high-powered rifle scope (10x or higher) to compensate for the distance. Use a bipod or shooting sticks to stabilize the rifle, and consider using a range-finding device or ballistic calculator to accurately estimate the distance and trajectory of the shot. Take into account wind direction and speed to adjust the aim accordingly, and make sure to hold off for a brief moment after the shot to allow for bullet drop and wind deflection.
