Since the onset of BC
variations seems to be consistently at or below Sg =
1.25, keeping the predicted stability above Sg = 1.30
is probably ample margin for error.
One might be tempted to try and design a rifle and
bullet combination to realize the increased BC of the
sweet spot observed near Sg = 1.23. The authors
think this is a bad plan and unworkable approach.
Even if the muzzle velocity can be held sufficiently
constant, Sg will change with environmental
conditions and shift the Sg out of the sweet spot. In
addition, the larger shot to shot variations in drag will
negatively impact long range accuracy and more
than erase the marginal gains from an average
increase in ballistic coefficient.
