Quick Answer
To assess the bullet drop of the .280 Remington, use the ballistic coefficient and muzzle velocity to calculate the trajectory at various ranges. The .280 Remington has a relatively flat trajectory, making it suitable for hunting at medium to long ranges. However, it's essential to consider the bullet's drop at 400 yards and beyond.
Choosing the Right Ballistic Data
When assessing the bullet drop of the .280 Remington, it’s crucial to have accurate ballistic data. The Remington factory load has a muzzle velocity of approximately 2,750 feet per second (fps) with a 140-grain bullet, and a ballistic coefficient (BC) of around 0.45. However, custom loads can vary significantly, so ensure you use the specific ballistic data for your ammunition.
Calculating Bullet Drop
To calculate the bullet drop at various ranges, use the trajectory tables or a ballistic calculator. For example, at 300 yards, the .280 Remington bullet drops approximately 24 inches with the Remington factory load. At 400 yards, the drop increases to around 42 inches, and at 500 yards, it’s approximately 63 inches. Keep in mind that these values can vary depending on the specific ammunition and atmospheric conditions.
Accounting for Atmospheric Conditions
Atmospheric conditions, such as temperature, humidity, and air density, can significantly affect the bullet’s trajectory. To account for these conditions, use a ballistic calculator that takes into consideration temperature, humidity, and air density. For example, at 500 yards, a 10°F increase in temperature can result in an additional 2-3 inches of bullet drop. By factoring in these conditions, you can ensure a more accurate shot placement at extended ranges.
