I was expecting an article on effective ranges of slugs and pellets fro use on game. Instead another "killing people" article. And those long ranges mentioned, "I once saw someone kill an elephant with a single number 8 pellet at 800 yards" .... about the same level as someone in a pub on boozed up conversation.

As for using shotguns for defence, obviously close range only. What use is their statements about someone killing at deer at 236 yards in such a discussion. My first thought is WHY is someone shooting at a deer at 236 yards with a shotgun in the first place?

For defence I think BBs to no. 4 pellets would be appropriate.
