For simplicity I'd like to keep the discussion between these 2 shotguns in 12 guage. Remington 870 Express, and the New Remington 887, which would you pick and why? From what I've heard the 870 Express is a cheaper version of the 870 Wingmaster,and the chamber on the Express needs to be polished to extact the cheaper ammo, which is what I'd be using. TIA
