between 1145 fps vs. 1200 fps at 35 yds with 1 1/8oz #8's in performance?
Shot size does matter. And you can't just divide distance by speed since the air slows it down (unless you are shooting in outer space). Also, the faster it starts, the faster it slows down.The shot size doesn't matter, it only matters that the load of shot is the same
So, I think you'd just divide the distance by speed.
35 yards is 105 feet so...
Not too much of a difference
