The issue isn't what you personally call your own stuff. It never has been. The issue is that the word/s is not what the item was called at the time,,,, and many of you insist on telling people outside of the "hobby" that it was. And this applies to many things that get argued over here in the same way.
Call you bag, on your own, whatever you want, but when someone asks about it on the range or out someplace you encounter the public, a shot pouch is a shot pouch, not a "possibles bag." Same goes for discussions within the community about gear and methods. Knowing the common misuse of the terms, when someone asks a question about a "possibles bag," I'm going to have to ask them to define their terms. Are they actually asking a out a shot pouch or are they asking about a bag for generalized stuff?
When you are gathering your stuff to leave for a shoot or hunt and can't find it and want to ask your significant other, "where's my "possibles bag?" in your best fake "mountainy man" voice,,,, go for it. But please stop telling the outside public that the people who would have originally used such a bag called it that.
You want to put your wife's apron around your tighty-whiteys and call it a breechcloth and then your bathrobe and call it a hunting frock and go shoot or hunt, and use your little short stick to start the ball? Go for it. But don't tell people this is what they wore and how it was done in the frontier and colonial days.
