by Bob Mayne of the Handgun World Show has a nice video up that destroys the myth that all you have to do is point the shotgun in the general direction of the intruder and fire. He shoots his Remington 870 from 5 yards – a good inside the house distance – and gets a nice 3 inch group.
Bob has an excellent podcast that is one of my weekly listens. It is part of the Gun Rights Radio Network and you can find the show homepage here.
