All I can say is, be patient. Go to the shooter's forum and check out some tips on shooting form; video your form and post it, and you will get some feedback that will help you shoot better. From the sound of things, you are shooting instinctively; the farther back you go, the harder it becomes to focus on a very small spot, which is necessary in order to shoot well with this method. Try shooting at a bag target spray-painted flat black, and stick a very small orange (or whatever color you see well) dot in the center of it, so that there is no other aiming point to distract your concentration. You will probably begin to group better. However, don't expect to shoot nock-breaking groups at 20yds and beyond. As long as you can put that first shot in a 6" circle, you'll be deadly on game. Good luck, Paul.
