Quick Answer
For elk hunting with a 7mm PRC, a muzzle velocity of 2,500-2,700 feet per second is ideal for achieving effective expansion and penetration. This velocity range should be achievable with a 24-26 inch barrel and a well-seated bullet. Aim for a velocity drop of no more than 100-200 feet per second over the first 200 yards.
Choosing the Right Ammunition
When selecting ammunition for 7mm PRC elk hunting, look for bullets with a weight of 150-160 grains. These bullets will provide the optimal balance between expansion and penetration. The Sierra Tipped MatchKing and the Hornady ELD-X are good options to consider. These bullets are designed for long-range accuracy and will help you make clean, one-shot kills.
Understanding Barrel Length and Muzzle Velocity
The barrel length of your rifle will play a significant role in determining the muzzle velocity of your 7mm PRC. A longer barrel will result in a higher muzzle velocity. However, increasing the barrel length beyond 26 inches may not yield significant gains in velocity. For elk hunting, a 24-26 inch barrel is a good starting point. This barrel length will provide a good balance between velocity and portability.
