Talking to a buddy and was discussing 16" AR10 308 vs 16" AR15 6.8 earlier so i ran the numbers.
Sure you can compare a 20" 308 bolt action to an AR. But keeping everything the "same" the 6.8 actually comes out looking pretty dang good considering the 308 might run 2# heavier.
308 with 165gr SST vs 6.8spc with 120gr SST
308 6.8
Range Elevation Elevation
(yd) (MOA) (MOA)
100, 0, 0
150, 0.62, 0.51
200, 1.82, 1.59
250, 3.3, 2.96
300, 4.98, 4.52
350, 6.84, 6.25
400, 8.84, 8.14
450, 11.01, 10.18
500, 13.33, 12.39
550, 15.82, 14.76
600, 18.49, 17.31
308 has about 150# more energy roughly 6" more drop at 600 yards.
