Just wondering what forum members feel is the best preparation for hunting Buff with Doubles with LIVE game--

Specifically to hit the animals properly and to shoot followup shots by leading them appropriately if they are running at an angle away or 90 degrees to you.

I don't do alot of wildfowl huntiing but I calculate that you must lead a Buff running at 90 dgrees across you at 25 mph about 16 inches.Obviously as the angle changes the lead changes.

Big Pigs?
?Whitetail-(probably too fast)
Feral dogs-(probably too fast)

Any suggestions??

Thanks to all!!
