Using the recipe below, the .450-400 NE 3" is capable of taking all game animals with the exception of elephant; a homogeneous or full-metal-jacket projectile is preferable for that application. Additionally, the load virtually duplicates the velocities of the original cordite rounds, so point-of-impact shifts shouldn’t be a concern.
