Hard to ignore the price differential, but at 650 yards, I'd be more concerned with accuracy than terminal performance. Gotta him em first, right? Suppose the V-Max shoot's .40 MOA and the BK shoots .60 MOA. That's a difference of 1.3 inches at 650 yards. If your shooting squirrels, that's the difference between a hit and a miss, assuming your wind and elevation calls are correct.
If your shooting past 500 yards and are twisted fast enough, don't overlook the 75g A-Max.
