Plus 1...as to the A-500...they were made for Browning by Beretta. Not a bad gun, but "best" automatic ever made....not really. It's claim to fame was that it was one of the first auto shotguns to reliably shoot 2 3/4" and 3" shells in the same gun without changing anything but the ammo. You might find that it will take a drop below $400 to move that Browning. 1100's are hard to find...20ga 1100's are about impossible. That Nylon 66 might even fetch $300 plus.
A magnum bolt face 700 with rust might also drop below $400. A Bushnell scope is not worth the time it takes to get it off the rifle and drop it in the nearest trash can...junk with a capital J!!!!!!! Might hold zero on a 22lr...less than zero chance on a 7mm mag.
