@akers06 if the gun shoots very well with plain old rifled slugs in the econo pack it won't be ammo picky. I don't know if you have a scope on your winchester. With a scope using the 15 pack 3" rifled winchesters it should shoot a 3 inch group at 60 yards. The light weight sabots do perform very well.
It's hard to take human error out of the equation with a shotgun. Mine kicks like a mule. After 5 or 6 shots I need a session with the 10/22 to stop flinching. I can shoot my Mosin Nagant more often than my shotgun without flinching.
