This in turn resulted in bullets with significantly higher sectional densities (.338 for a 410gr .416 bullet and .330 for a 400gr bullet), which correspondingly penetrated much more reliably than the old big bore rifles. Norma adopted the design and standardized it with CIP in 2010. The .338-378 has devoted fans in the long-range hunting sub-culture, but only exceeded the .340 Weatherby’s muzzle velocity by 119 fps; a small reward for the huge recoil it produces.
