The price of new semi auto shotguns on this list range from $700 to more than $2,000. You might be surprised to learn that a used $500 to $700 auto-loader can be as reliable as more expensive options (and last just as long). This is particularly true of autos from the 1970s, 80s, and 90s. The Remington 1100, Benelli Super Black Eagle I and M1 Super 90, Beretta’s 300 series, and of course the Auto-5 are just a few of the classics that are still kicking today.
