Are we really saying that the concept of loaded is so complex that there isn't a single definition that applies across the board?
No, I think there is a single definition that could be applied across the board, but some folks are not willing to accept it as valid.
Further complicating matters are the legal definitions of "loaded gun" which range from "Loaded=requiring only a single act to fire the weapon" or, "having a round in the firing position" to "Loaded = weapon and ammunition in the same vehicle compartment".
Historically speaking, repeating arms have only been around for what? 150 years or so?? AND, those arms that existed before repeaters are still with us as well.
The American Heritage dictionary gives a definition of loading as "charging a firearm with ammunition". Indeed, this is the common usage. We load ammo into the gun. Once that is done, the gun is "loaded".
WHERE in the gun the ammo is, is a different matter. Gun design makes the difference where the ammo goes, and whether or not it can be fired with just a trigger pull, once there.
Ok, let's start with some basic premises we can all agree on.
Premise 1: There is value in distinguishing between loaded and unloaded because it provides insight into whether or not a firearm can be discharged.
agreed
Premise 2: A firearm that can be discharged by pulling the trigger is not unloaded.
agreed
agreed. (added for clarification - an open bolt action ALWAYS has the chamber empty, except at the moment of firing. Pulling the trigger releases the mechanical action to load the chamber and then fire the round as a single continuous action. Absent mechanical failure of the gun or the ammo, an open bolt gun WILL FIRE when it chambers a round)Fact: A firearm that operates from an open bolt can be discharged by pulling the trigger even if the chamber is empty as long as a loaded magazine is installed.
agreedIt follows from the starting premises and the stated fact that a definition of unloaded that states "chamber empty" = "unloaded" can not be correct because it results in an "unloaded" firearm that can be fired by pulling the trigger.
There are many gun designs where loading ammo into the gun makes them ready to fire. Single shots and double barrels. For these guns, and ONLY these guns a definition of "chamber empty = unloaded" is generally accurate. For repeating firearms, it is not.
I believe that you have to be able to separate "loaded" from "immediately able to fire" for a constant and applicable definition.
Absolutely, every gun that is immediately able to fire IS LOADED. No question there. (note, I did not say "has a loaded chamber") BUT, not every gun that is loaded is immediately able to fire.
I think that the best definition for common use of "loaded" is "ammunition in the gun". All our common use terms and phrases have that in common, in order to be loaded, there must be ammunition in the gun. It can be, but does not have to be in the firing chamber.
I think legal definitions for transport, and game laws defining "loaded" as anything other than "ammo in the gun" ought to be a separate discussion. Those laws are for specific situation, and as we have seen, can vary a lot from the general use term and even physical reality.
In common English, when you place ammo in a gun, you are loading the gun. When you put ammo in a magazine, your are loading the magazine.
Putting ammo in it, loads it. Period.
Just my opinion, but I don't see how you can make a case for anything else.
