Neat old 12 gauge shotgun shells

I love reading this forum, so many different and odd types of ammunition, so much knowledge, and I love that there are people from all over the globe here.
In the last year or so I have inherited some old shotgun shells that my Great Grandfather, Grandfather, his brother and my dad had shot years ago. There are some that are pretty neat.

These are my favorites. My grandfather loaded these cardboard shells, #4 buckshot for shooting geese. I now hunt with #4 buckshot for varmints and predators.IMG_6526 This one is pretty interesting. A 2 3/4 magnum shell that says to be only shot in 3 inch guns.
