The gun is almost two years old. I would say that it has had between 1,000 and 1,500 shells fired through it. So it's not worn out or anything.Imainly shoot 3 inch, Winchester DryLok #3 or #2shells through it. I have also used it on dove shoots, in which caseI shoot 2 3/4" dove loads.The gun has no corrosion, rust, or any type of fouling anywhere on it. It has been very well maintained.
