Quick Answer
To zero a .338 Federal rifle for elk hunting, first determine the rifle's effective range, then use a chronograph to measure the muzzle velocity. Next, use a ballistics app or calculator to calculate the rifle's trajectory and zero the scope at 300 yards, adjusting for bullet drop and wind deflection.
Choosing the Right Ammunition
When selecting ammunition for elk hunting, look for heavy, flat-shooting bullets like the 210-grain Hornady InterBond or the 225-grain Nosler AccuBond. These bullets offer excellent penetration and expansion, making them well-suited for large game. Opt for a muzzle velocity between 2,800 and 3,000 feet per second to ensure adequate kinetic energy for a clean kill.
Zeroing the Rifle
To zero the rifle, first determine the effective range of the rifle by shooting at a target at varying distances. Next, use a chronograph to measure the muzzle velocity of the chosen ammunition. Then, use a ballistics app or calculator to calculate the rifle’s trajectory and determine the zero point at 300 yards. This will account for the bullet drop and wind deflection, providing an accurate shot at longer ranges. Adjust the scope accordingly, ensuring the scope is set to the correct zero point for optimal accuracy.
Range and Wind Considerations
At longer ranges, wind deflection becomes a significant factor. Use a wind gauge or a ballistics app to determine the wind deflection at the target range. Then, adjust the rifle’s elevation and windage accordingly to compensate for the wind deflection. Additionally, consider the terrain and any obstacles that may affect the bullet’s trajectory, such as hills or valleys. Adjust the scope accordingly to ensure an accurate shot.
