Thanks MtnHtr. Some of the Wby published MV numbers are a bit optimistic, some are fairly accurate, and some of their downrange numbers are illogical. For example, for the 6.5-300 (https://weatherby.com/store/6-5-300-weatherby-magnum/), they have, at 500 yards, the 140gr AB going 76 fps faster than the 140gr Interlock, but they have the 140gr Interlock putting out 163 fpe than the 140gr AB at the same distance.
