Put a 1 inch or 1/2 inch piece of bright colored paper on your target. Concentrating on a smaller target will make you make you shoot tighter groups. I have been doing this for a couple of months, it's the best shooting I've ever done. 1st timeI put the piece of paper up brought my groups at 20, 25, 30, 35, and 40 to about a 1 inch diameter around the paper. Before I was always shooting right on the fringes of the 3 inch target on my block. Just thought this could help some people out.
