Craig, i totally agree!
But Lonnie asked two questions:
How do I aim at running targets?
How much do I lead?
The math will tell you how much to lead, all conditions remaining constant. When he asks how much to lead a running coyote at 100 yards, i think an answer of "about three feet," sounds better than "as much as it feels right."
An estimate of 3-4 foot lead at least puts Lonnie's shots inside a small buffalo.
