i have 2 turkey guns
one is a remington super mag with factory turkey choke,,,,,the other is a mossberg 835 ulti mag, and its ported barrel and ported kicks choke,
now as for recoil the 835 has more being ported but when you shoot both at 40 yards the wad from 870 is about 3/4 way to the target and the 835 is dropped about 15 yards from gun,,,,,,
