You’d be amazed what you can miss with a shotgun.
I know , Front Sight shotgun class was fun ;)
A normal length shotgun doesn’t scatter as wide as some might think. At 10 yards/30 feet (imagine 5 six foot men lying end to end) the spread of an effective pattern is not going to be much more than a foot.
Its not like you can just point the gun at the room and hit everything in it.
So you can be amazed at what you can miss with a shotgun. I do it all the time at the range. And don’t even think about talking to me about dove shooting.
