I was shooting pretty much on target, but had a somewhat unorthodox two hand grip. Right hand shooter, left eye dominant. Instead of the normal right thumb top left thumb under grip, I was gripping with my right thumb in the normal position but my left thumb was positioned around my right hand at the base of my right thumb.
Since I switched to the right thumb top, left thumb under both pointing forward, I've been hitting low left of target. Looking for suggestions.
