I shoot a Remington 870 express mag with a Simmons pro diamond 4 power scope. Shooting lightfield sabots I can shoot a 4" group at 100 yards max range is about 150. Good gun and has killed alot of deer. Plus throw a differed barrel on it and it also a turkey gun, bird gun and waterfowl gun. My dad shoots a h&r slug hunter with the bull barrel shooting lightfields with a nikon 3x9x40 scope. He shoots them touching at 100, 4" at 150 and about 6" at 200. Thing weighs as much as a small cannon (because it is) but man is it a tack driver! Great gun and affordable. Single shot action turns some people off but I like it. Only takes one to put a deer down.
