According to the accuracy: How much is the difference between the 20" and the 24" Barrel expressed in MOAs in distances from 100 to 300 yds ?
If we use the assumption that one gains about 25 fps for each additional inch of barrel length, there would be about a 100 fps difference between the two barrels. If we use a 168 grain bullet as you asked about, and assume that you are able to push this bullet at 2700 fps from a 24" barrel (this is easily done), you would have about 4.4 MOA drop at 300 yards, assuming a 100 yard zero. If we assume that you drive the same 168 grain bullet at 2600 fps from a 20" barrel, you would have 4.9 MOA drop at 300 yds, again assuming a 100 yd zero. So, a difference of about 1/2 MOA, or about 1 1/2" at 300 yds, if the assumptions we are working under here hold true in reality.
