[QUOTE="elkaholic, post: 1637085, member: 13833"] It's because of your bore size to weight ratio. With a .308, you have more force being created on a larger cross section bullet. Look at it this way; if you have a 10mph wind blowing against a 50 sg ft sail vs a 100 sq ft sail, which boat will go faster! The downside is, it will start faster with a .308 but will lose velocity quicker (bc) so at some point, the 7 mm will take over with velocity, trajectory and energy. It just depends on your game as to which you want. In general, the 7/08 wins the competition at extended ranges [/QUOTE]
