Cause everyone finally figured out that when you have two types of shot, one round and the other this flightstopper stuff, with a raised ridge around it, past thirty yards or so it takes your shot string and stretches it out quite a bit. I know I know some guys are gonna say they killed geese at 65 yards and they may have, but that flightstopper is going to lose velocity quicker than the other shot. So now at least its more consistent maybe? Not sure but thats my guess.
