Is it worth reloading .308 for elk hunting?

Choosing the Right Bullet

When considering reloading .308 for elk hunting, the type of bullet used is crucial. A heavier bullet with a larger diameter, such as a 150-170 grain spitzer, offers better performance on larger game. A good starting point is to use a bullet that has a ballistic coefficient (BC) of at least 0.5, such as the Sierra GameKing 165 grain. This will ensure the bullet retains its velocity and maintains its trajectory at longer ranges.

Pressure and Velocity

To ensure the .308 cartridge has enough power for elk hunting, it’s essential to understand the relationship between pressure and velocity. A minimum of 50,000 psi (pounds per square inch) is recommended for elk hunting, which translates to an average muzzle velocity of around 2,700 feet per second (fps) with the Sierra GameKing 165 grain. This can be achieved by using a suitable propellant, such as H4831SC, and loading the bullet to its optimal seating depth.

Reloading Considerations

When reloading .308 cartridges for elk hunting, it’s essential to consider the case capacity, which should be around 45-46 grains for optimal performance. This will allow the propellant to burn efficiently and produce the desired velocity. Additionally, using a suitable powder measure and ensuring consistent loading will help to minimize variations in pressure and velocity.
