Can somone explain to me the proper use of a butt hook? I have a general idea but wasn't sure if there was a proper way to grip it or? Sorry for my newb question, everyone that I shoot with are Benchrest guys so knowone has a hook or knows anything about one. My gun is a remington 700 xcr tactical long range in 308, so it has the b&c tactical stock with the butt hook. Thanks in advance.
