I am looking for any suggestions for books or video's on shooting doubles, I do not get any better (F grade) since I started shooting trap several years ago, for instance at this weeks league shoot I was 24-24 singles, 24 HCap but 22 in doubles. I can get the first bird but the second seems to elude me most of the time and when I really concentrate on just the second bird I usually lose the pair, I am conscious of not lifting my head for a peekaboo and have tried different leads and body/feet positions with no success, any thoughts would be appreciated.
