Have been gunning many years. Always used a Beretta in the early days, then a Benelli. All with modified choke and 00 Buck. Headsets to the pilot help greatly. Gun barrel always down and forward, and further down when banking into the shot. Wait for the shot, follow, once and DRT… Much easier in the fall or winter for visual. Once flew with an Army gunship pilot - that day was a wild chopper ride! Some of the comments he made were priceless when we rolled one up in the STX brush!
