First off, full and super full will cause horrible patterns. Modified will probably produce best. Second, its about the most ineffective setup one can use. I have been on two hunts with it. And I won't use it again.

They use it alot here in MD for sika deer hunting in the swamps. Kinda like jump hunting. I was with a group who all vollied 3 rounds at a sika at 35 yards, and I happen to be using sluggers and took it down.
