I know it’s contrary to how most of us typically do things, but try to spend a little money with the local businesses if you can. Buying a few boxes of shotgun shells in a common size saves a lot of carrying burden for you and just might help a little mom and pop hardware store where you get your license at.
That’s how I ended up with so many boxes of active shells. They were just on the shelf at a hardware store on my way north.

Out there doing it best I can.
