i read an article the other day that talked about how to make your self a better shooter at longer ranges and to extend your range , and to make yourself at long hunting shots, the article stated that you should be practicing at double the range of your farthest hunting shot that you will take, like if your max is 40 you should practice out to 80 and so on. it will make your 40 yard max shot a lot easier than ever before because your not as worried about the distance. it is a great confidence builder practicing this was it will make you a lot better shot in close, at those ranges every little thing is important and plays a huge part in the shot flaws in form will be magnified. so it helps to fix these flaws becuase they will be easier to identify
