OK with out knowing the velocity's of each round I don't no for sure . I ran some known 308 cartridges in those weights through my ballistic calculator .
Federal 168gr GMM , Velocity of 2650fps
Zeroed @ 100yds the rest are drops in inchs - 200yds 4.3" / 300yds 15.4" / 400yds 34.6" / 500yds 63.3"
Hornady 150gr SST , Velocity of 2820fps
Zeroed @ 100yds the rest are drops in inchs - 200yds 3.7" / 300yds 13.4" / 400yds 30.4" / 500yds 56.1"
As you can see it is likely the 147gr bullet will have a faster velocity therefore it will shoot flatter and just a bit higher .
Hope this helps
P.S. remember the ACOG is designed to shoot minute of man and not moa so those hash marks will be general guide lines and not likely law .
