Pattern your shotgun
If you carry a shotgun in your squad or have one as a home defense gun you owe it to yourself to know how the weapon patterns its’ shot with your carry load. Here is a quick way using one target. Fire the load at five yards. Then with a marker, play “connect the dots” to show the outside diameter of the shot pattern. Using the same target and same aim point repeat the process at 10, 15, 20, and 25 yards.
