Quick Answer
To refine your varmint load for optimal coyote performance, consider using a 223 Remington cartridge loaded with a 55-60 grain bullet, such as the Hornady V-Max or the Sierra MatchKing, at a muzzle velocity of approximately 3100-3200 fps. This combination offers a good balance between range and terminal performance. Experiment with different loads to find the optimal setting for your rifle and hunting conditions.
Choosing the Right Bullet
When selecting a bullet for coyote hunting, consider the type, weight, and profile. The 55-60 grain bullet is a popular choice for varmint hunting, as it provides a good balance between range and terminal performance. Bullets like the Hornady V-Max and Sierra MatchKing are designed to expand rapidly on impact, creating a large wound channel and increasing the chances of a quick kill. The V-Max features a polymer tip that enhances expansion, while the MatchKing is a hollow-point bullet with a flat base that provides excellent accuracy and expansion.
Muzzle Velocity and Range
To achieve optimal performance, aim for a muzzle velocity of approximately 3100-3200 fps. This range allows for effective range extension and ensures that the bullet remains supersonic at longer distances. When loading the 223 Remington cartridge, consider using a light to medium weight charge of a fast-burning powder, such as Varget or H335, to achieve the desired velocity.
Load Development and Tuning
To refine your varmint load, conduct a series of load development tests using different bullet weights and powder charges. Start with a baseline load and adjust the powder charge in small increments to achieve the desired muzzle velocity. Use a chronograph to measure the velocity and a shooting bench to test the accuracy of each load. This process will help you identify the optimal load for your rifle and hunting conditions, ensuring a quick and humane kill on coyotes.
