So on Thanksgiving my brother-in-law and I decided to shoot a little. When I got back up to the house after we shot 4 shells through my shotgun I noticed something a little strange about the empty casings--2 of them had pits/holes where it looked like the buckshot had go through the side of the casing. Is this normal? The shells were my grandfather's and probably at least 10 years old, could that affect how the buckshot is pushed out of the shell?
