This thread reminds me of a gun museum in Reno, Nevada. My wife and I went to this museum years ago while we were on our honeymoon.
Anyway, one of guns that I remember the most was a 4 guage shotgun. Yes, 4 guage!
This shotgun was mounted to the front end of a camoflaged row boat and then it was used to sneak up on a bunch of water birds sitting on lakes. The idea was to shoot as many birds with one shot as possible.
This was back in the day when all the ladies had to have hats with lots of feathers in them. This type of "hunting" is outlawed today.
Anybody else been to this museum?
