I am sure they would be impressed with your letter. It doesn't matter one iota what BATF acalls something, each state is able to make their own definition of a legal firearm for hunting. What would make you think any state is bound by a federal definition of a firearm in making regulations for legal firearms in that state. You seem to forget about states rights and when laws are passed, defininitions are set to describe what is legal and those definitions do not have to be what you think they should be. The question I posed is a letgitimate question, your reaction to the question is ridiculous. Designating a rifle by gauge instead of by caliber doesn't make it a shotgun. and that gun may not pass muster in some states as a shotgun. I really don't care, but that is a fact, and I posted it as a matter for discussion, not to be told what the feds do or say, because it doesn't matter what they call it, if a state says it isn't legal to use, it doesn't matter what the feds call it. I have an American Derringer that will fire .45 colt ammo or .410 buckshot or shot shells or rifled slug ammo, it is not a shotgun, it is a .45 caliber handgun that will accept .410 shotgun shells, there are revolvers that will shoot .45 colt ammo and .410 shot shells, they are not shotguns, they are .45 caliber handguns that will accept .410 shot shells. The 24 gauge gun in question here could very easly be considered a 24 ga. rifle that can accept a 24 ga. shotshell, even though it was not made for a shot shell. That is the question I posed and your response did not put that question to rest.
