The high the bc of the bullet the better an on most bullets the bigger they are the higher the bc is a big bullet with a high bc will out run a smaller faster bullet down range an less wind drift I just went with the 168 to lighten up the recoil
Good point. A friend shoots a 257 weatherby and I shoot a 264WM for deer. I loaded for both and we learned that with a 250yd zero his gun shooting 110gr bullets fast is 2" flatter at 400yds, but mine drifts 2" less in the wind with slower higher BC 140gr bullets. Two different ways of getting pretty much the same trajectory at that range. The difference does increase with range, but it shows that at normal ranges there is more than one way to get similar results.
