When people have to ask about what "One shot, one kill" means, I get a little scared... especially if they're a gun wielding hunter. I start to think maybe that person needs more learnin' to do or to get more edumucated... and maybe that person should develop fundamentals and philosophies that will make them a better hunter. I get all sorts of crazy ideas if I heard that. LOL! Anyway, to me, the idea or principle of the "One shot, one kill" is all about taking the one shot you have in front on you and doing the best you can with it. That goes for your form, mental conditioning and using the right weapon for the job. It's a mentality... a state of mind.
