Diggory has a point. Eliminate the automatic cocking and ejecting system, and you have a gun that will last forever. However, some of our automatic cocking guns seem like they are going to last forever. Longevity of our guns is not a big problem. Getting the time to shoot them is the big problem. Most of my life, I have fired a shotgun at least three days a week and have participated in five or more competitive disciplines on an irregular basis. I have never succeeded in shooting a side by side gun loose yet and that's about all I've shot for most of my life except for competitive skeet.
