Quick Answer
The ideal bullet drop calculation for .338 Federal typically ranges between 10-20 inches at 300 yards, depending on the bullet type and rifle configuration.
Bullet Drop and Wind Deflection
When hunting elk at longer ranges, bullet drop calculation is crucial for accurate shots. For a .338 Federal with a 250-grain Speer SP bullet, the ballistic coefficient (BC) is approximately .470. Using a ballistic calculator or chart, we can estimate a bullet drop of around 12-15 inches at 300 yards. However, wind deflection also plays a significant role, especially in mountainous terrain. A 10 mph crosswind can deflect the bullet by approximately 2-3 inches at 300 yards.
Windage and Elevation Adjustments
To compensate for wind deflection and bullet drop, hunters must make accurate windage and elevation adjustments. For a 300-yard shot with a 10 mph crosswind, a 3-5 MOA (minutes of angle) windage adjustment is typically necessary. In elevation, a 12-15 inch bullet drop at 300 yards translates to a 4-6 MOA elevation adjustment. However, these values can vary depending on the specific rifle, scope, and ammunition used.
Practical Application for Elk Hunting
In practical terms, elk hunting often involves shots at longer ranges, typically between 200-400 yards. For a .338 Federal, a 250-grain bullet with a BC of .470 is a suitable choice. By using a ballistic calculator or chart, hunters can estimate bullet drop and wind deflection, making more accurate windage and elevation adjustments. This knowledge enables hunters to make effective shots at longer ranges, increasing the chances of a successful harvest.
