I have been putting together some money to move from an old pump shotgun to an auto. I've tried to see and hold several models. Of the ones I can afford, I like both the Beretta A300 and the Winchester SX4. I will likely go with a used one if I can find a good one for a fair price. I'm curious what guys who have used these properly, wet, muddy duck blind hunts, what the experience has been.
