Leshma, it's not BS, but I know you are a forum troll so w/e. Btw, this IS NOT CHAMBERING I merely discovered this while TRYING TO chamber.
People think it is just "Moving the hitbox." It is not!
The arrow or throwing weapon goes CLEAR THROUGH your upper body or head!
There is NO noise caused by this.
I am sorry I can't Fraps it, because I have no idea how, but like I said earlier, you guys can test this FOR YOURSELVES
Bold font for those in which it answers responses to.
Edit*- To test this for yourself, position yourself infront of an archer or thrower with an upper swing ready to swing (above your head). Let the swing go just as they let their shot go, and there you have it! Sometimes it will whiff due to bad timing though.
