Hitting what you are aiming at is the name of the game. Every quality made air gun has its magic pellet. With a gun vise, and several weights of pellets, it is fairly easy to find the magic pellet. Once you have the magic pellet, zeroing your scope is a "no-brainer." In this Suspense Filled Thriller, world famous director, actor and producer Dirt E. Harry shows you step by step how to zero any scope. So do yourself a favor, stop by my website http://www.topairgun.com and Make, My, Day!!
