Fail.
Code:
_Bullet_ _BC_ _MV_ 0 500 1000 1500 | YARDS
300WM 210VLD 0.631 2850 > 2850 2187 1628 1213 | velocity (fps)
300WM 185Hyb 0.569 3025 > 3025 2268 1639 1186 | velocity (fps)
6.5 140 0.612 2820 > 2820 2143 1577 1172 | velocity (fps)
300WM 210VLD 0.631 2850 > 0.00 13.17 60.58 157.28 | wind (inches)
300WM 185Hyb 0.569 3025 > 0.00 13.58 63.37 167.28 | wind (inches)
6.5 140 0.612 2820 > 0.00 13.84 64.06 166.49 | wind (inches)
@ 1400 yards
300/210 685 ft*lbs
300/185 577 ft*lbs
6.5/140 426 ft*lbs
@ 1000 yards
300/210 1234 ft*lbs
300/185 1102 ft*lbs
6.5/140 772 ft*lbs
Even if you could fire a 140 at 3000 fps from a 6.5 CM, using the same conditions as above it would only retain 1702 fps at 1000 yards and still have 27% less energy.
