[QUOTE="AFraser, post: 1662857, member: 45498"] Dave, That kind of trajectory from a .308 bullet needs a bc of around .520, and I can't find anything over ~.460 on the market, so I wondered what bullet you assumed. Also, I think the military value the much lower recoil of the 6.5 CM cartridge. In your example muzzle energy would be 2894 ftlbs for the .308-155, vs 2266 ftlbs for the 6.5-140 = +27% increase.
