Having always been a rifleman, I know little of shotguns. I fired a single shot straight stock today with a 3" WW magnum 1 1/4 oz shot. One shot was enough. I wish to get a shotgun and note on the Mossberg site that barrels are ported. Will this reduce recoil that much in a 20 gauge with the shell listed above? In 12 gauge, is the recoil controlable with the ported barrel. Thanks, Byron
