If you are attempting to emphasize “American” you should really skip your last point. Weatherby Vanguard actions and barrels are made by Howa, a Japanese company. Nothing wrong with Howa, but they are not American. Also, some might say the .243 is a little below minimum performance for some North American big game; sure, it will work, but it is a bit underpowered.
Nothing wrong with .243 though...
