Is a .308 flat shooting enough for elk in open fields?

Ballistic Considerations

A .308 Winchester rifle firing a 150-grain bullet at a muzzle velocity of 2,700 feet per second (fps) will experience a drop of approximately 24 inches at 400 yards. While this may not be excessive for a relatively flat trajectory, wind deflection can still be a concern, especially at longer ranges. A 10 mph crosswind can deflect the bullet by up to 4 inches at 400 yards, requiring a skilled shooter to compensate.

Shot Placement and Range

When hunting elk in open fields, it’s essential to consider the optimal shot placement. A well-placed shot to the vitals (heart and lungs) is critical for a quick and humane kill. Given the potential for bullet drop and wind deflection, it’s recommended to aim for a spot 1-2 inches below the animal’s spine, taking into account the expected bullet drop. At ranges beyond 300 yards, a scope with a generous eye box and good holdover marks can help compensate for the bullet’s trajectory.

Shooter Skill and Equipment

A shooter with exceptional skills and experience can still rely on a .308 for elk hunting in open fields. However, a more forgiving cartridge or a rifle with a flatter trajectory, such as a .300 Winchester Magnum or a 6.5 Creedmoor, may be preferred by many experienced hunters. Additionally, using a scope with a ballistic reticle or a rangefinder can help compensate for bullet drop and wind deflection, making the .308 a viable option for more skilled shooters.
