I stopped watching O'Reilly a few months ago when I finally had enough of his pontificating. But, I saw parts of the show that is referred to. Heavy weapon - never heard the term as relates to small arms. Buying a bazooka or machine gun. Give it a try and see how that works out for ya. Buying ammo - what about making it? I used to reload about 25 years ago. All my reloading equipment is packed away in boxes, sooooooo. Bet ol' Bill hasn't thought about that nuance to ammo acquisitions. Why isn't the media talking about the 71 year old guy who dispatched the two guys in hoodies in the Internet cafe? He saved the day but no one wants to discuss that.
