What is the max distance shotgun shot travels for say 7 1/2 bird loads? I don't think I have ever seen a chart for anything but rifle rounds etc. Sometimes I want to make sure I am not encroaching on another property owner. Anyone seen such a chart for shotgun loads?

Understanding Firearm Ballistics by Robert Rinker. Available at your local B&N.

A French officer, General Journee, discovered that the maximum range of shot pellets in yards could be found by multiplying the diameter of lead shot in inches by 2,200. Velocity and choke have such little effects, they are not included.

Not perfect, as the US Army has done some testing also...but all the formulators can't agree on what is right and what is wrong.

BTW, this is for lead only.

Diameter * 2,200 = max distance

7 1/2 is .095"

.095" * 2,200 = 209 yards

Hope this helps.
