Quick Answer
Bullet drop for a .204 Ruger on coyotes is influenced by factors such as muzzle velocity, bullet weight, range, and atmospheric conditions, particularly temperature and humidity. The cartridge's relatively high velocity but low mass causes it to drop more steeply than heavier, slower cartridges. Understanding these factors helps hunters compensate for the bullet's trajectory.
Atmospheric Conditions
Atmospheric conditions significantly affect bullet drop. Wind and temperature changes can alter the trajectory of the bullet, causing it to drop more or less than anticipated. On a warm day (60-80°F/16-27°C), the .204 Ruger’s bullet drop is less than on a cold day (40-50°F/4-10°C) due to the lower air density. For example, at 400 yards, a 32-grain bullet dropped 43.5 inches on a warm day but 54.5 inches on a cold day. Hunters should use a ballistic calculator or consult a chart to determine the bullet drop based on the expected atmospheric conditions.
Range and Bullet Weight
The distance from the shooter to the target also affects bullet drop. At longer ranges, the bullet drop increases exponentially. A heavier bullet, such as a 40-grain projectile, drops less than a lighter 32-grain bullet at the same range. At 400 yards, the 32-grain bullet drops 43.5 inches, while the 40-grain bullet drops 33.5 inches. Hunters can use a ballistic calculator to determine the best bullet weight for their specific hunting conditions.
Muzzle Velocity
Muzzle velocity is another critical factor influencing bullet drop for the .204 Ruger on coyotes. A higher muzzle velocity, such as 3,800 feet per second (FPS), results in a flatter trajectory than a lower muzzle velocity, such as 3,500 FPS. At 400 yards, the bullet drop difference between these two velocities is approximately 10 inches. Hunters can adjust their aim accordingly to compensate for the bullet’s trajectory based on the expected muzzle velocity.
