It might be the best thing that ever happened to your archery skills. All the good archers in this forum are always trying to get people to shoot at close distances at a blind bale, in order to improve their form. If you have good form, the only other things you need are good concentration and a little practice at the distances at which you plan to shoot. Most of us get a lot of practice at the distances we want to shoot, and never fully develop our form, so we really never reach our potential as archers.
When I attended the Black Widow instinctive shooting clinic, all of our shooting during class time was at blind bales. I thought, this is going to be boring, which it was, but I could never have learned good form if we were shooting at targets 20+ yards away. Fortunately, Fred Asbell and Ken Beck kept us entertained.
That was fine for the clinic, but the problem I had after I got home was,I didn't see how I could improve my form if I was just shooting arrows into a bale all by myself. Wouldn't I just be reinforcing bad habits?
Actually, no. When I started doing it, I discovered that removing the distraction of distance, I could concentrate on my stance, body position, draw, and release, in a way that I could never do when shooting at targets a normal distance away. I found that when I had good form, three arrows often flew into the same hole, to the extent that I had to shoot at different points on the bale to avoid busting arrow nocks. My accuracy became so good at about 10' that if you extrapolated it out to 20 yards, I should be shooting fist sized groups all the time. Which I certainly don't do, because other variables enter the picture.
If you haven't had any formal training, you can learn good form from instructional DVD's or books. It's pretty easy to get the concept of what good form is, but harder to recognize whether you are actually doing it. Make a video of yourself shooting from various angles, and you'll probably be able to pick up on most problems. Send the video to this forum and people might be able to help you pick up on more subtle things.
