A very close friend of mine is a dedicated waterfowler who hunts at least 2 days per week for the entire season. He would like to go "Old School" and get a 3" Superposed as his go to gun. My concern is how well it will hold up to shooting 3 inch steel shells through it at a reasonably high volume. And it will be mostly steel I can assure you. I understand the better no-tox alternatives available for vintage guns but lets assume 75% of the shells it digests will be high velocity steel. The chokes would be professionally opened accordingly. Have any of you any thoughts or experience in this arena? Thanks in advance. Dan
