As you would expect, the "best" shooting method is and always has been a hotly debated topic. Shooters who frequent the tournament circuit are always looking for that "1 thing" that might give them more X's, hence the "best" shooting method invariably rises to the top of the discussion checklist.
So who's teaching the "best" shooting method out here? Why I am of course. That said, it is commonly known—and true—that various successful and rightfully respected teachers around the US don't teach the same shooting methods. And trust me, those teacher's methods work, and work very well thank you. Proving not just one but several points.
First, there are—and always have been—multiple ways to break a target, consistently and reliably. Second, following the sound advice of a competent teacher will not only get you the X, but will teach you—precisely—what to do and how to repeat that successful shot again and again. Third—and in my opinion the most important point here—your application of this shooting method, correctly or incorrectly, will ultimately determine the result of each shot and your rate of improvement.
Right now, this is the very best time to consult with a teacher to learn why you are not consistent in the shooting box. There are no mysteries here, just unanswered questions. Teachers, and especially Paragon Professional Associate teachers, have those answers,...and the "best" shooting methods.
