[QUOTE="gilk1, post: 2296527, member: 38214"] External ballistics. The 30cal bullet is not very aerodynamic until 230gr + (source: Litz, Applied Ballistis). The medium-heavy weight 7mm bullets are more efficient (aerodynamically) than heavy 30cal bullets and fly faster = more range, more KE, less wind drift. While they share the same parent cartridge, the 300wm uses more powder to produce less performance. [/QUOTE]
