Since I was self taught I had to deal with form issues and a LOT of them. Looking back now I shouldn't have gone hunting when I did but I did kill a pair of does last year that I was lucky on both to find due to my assorted screw ups that should not have happened. Around a few months ago I watched a video with a man claiming to have issues with shooting down and to the right, the same issue I had. From reading the comments on the video and on here I steadily corrected my form and release through blind bail shooting and play shooting at the cat and dog (Acting like you are drawing and releasing while picking a spot without your bow in hand)
Having been sick for a few days I finally got out to try my shooting again for the first time in a few weeks. The first two shots were within 3 inches but I knew it could be better. The final two shots were a 10 ring and an 8 ring from 17 or 18 yards. I rarely shoot that well intentionally. All I can say is thank you to all of you who give advice to guys like me!!
