Hey... shotguns are machines and like all machines parts break and/or wear out. When we used to go to SA shooting in the eighties we took two shotguns each...and not because we were double gunning the doves. Same as when I used to shoot a lot trap. Two guns, as invariably one would break while on the line. I'm a believer in O'Flannigan's law....he thought Murphy was an optimist.
