I would say for most high volumn clays shooters 30K would only be a year on a gun. I know for a fact I have put 150 flats thru one of my Benelli's in just over a year and thats only counting clays shooting. Not a single hick-up.
I have heard of stories about some Benelli's not shooting but I can honestly say I have never seen or known a single person that has had issues.
Did I mention I only need to clean the Benelli to keep the rust at bay?
