I think we all realise just how rare & unique the treasure that you now have before you Cap!
As the caretaker of this wonderful little piece of history, I hope you have many years together just having a bit of fun whether it be punching holes in paper or shots at game.
More so a rook type cartridge I suppose, but then again if the opportunity presents itself at bigger game, I think you'd have a winner here regardless!
Looking forward to your range report like all the other mere mortals wishing we were in your shoes,
Well done indeed mate.
