Hi I was recently given a lot of 12 guage shot shells.
The person that gave them to me said that they were reloaded years ago. He also said that the person that reloaded them was a novice at reloading and that one of the shells caused a newer winchester shot gun to explode.
My question is should I dispose of them or could a shot shell be loaded so in correct as to expolde the gun?
they are all loaded in AA lo base brass.

Thanks
Don
