I completely disagree with the pattering you gun with diffrent loads. It makes a huge diffrence our ancestors didnt have the technologic advances that we have today if they would have patterned their guns with the hundreds of loads and chokes we have they would have killed more birds. I shoot 3 1/2's at everything in sizes 4-BBB the bigger the bird the bigger the shot. Get out there and pattern your guns, its fun and I promise you will shoot more birds.
