Anyone have an opinion as to the best shotgun for high volume shooting. This would be for dove shooting in Argentina, 1,000 - 2,500 shells a day. I have tried 1100's (wouldn't cycle the Mexican Remington shells), 11-87's (OK, but inconsistent and needs constant attention), and a BPS (worked great but it nearly beat me to death). I also shot with some guys from California or New york or something who were very proud of their shiny new Beretta's but their guns couldn't handle the dust worth a damn. These were all 12 gauges. I am thinking of going to a 20 gauge and maybe a pump. I have been disappointed too many times by automatics that jam up. Only problem is I had my 870 jam consistently with remington cheapo 3 inch 2's, I had to borrow a Benelli Nova pump which fed that junk flawlessly.Any opinions welcome
