Re: Cartridge Chamberings?
Alpo, thanks for the time you took putting it together! The listed link has both the name interchangablility AND the cartridge interchangability, but I admit it is not nearly as well layed out as what you put together here, nor is it as complete.
"...As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprise, and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body, and stamp no character on the mind. Let your gun therefore be the constant companion of your walks."
