Can anyone recommend some resources for learning to shoot better from field positions (standing, kneeling, sitting)? Seems like there are a lot of opinions out there, and it's hard to know where to start. I feel very confident shooting off something solid, but otherwise my shooting is not good at all. I recently bought a bolt action .22 and am trying to put a ton of rounds through it, but I don't want to develop bad habits. Any videos, articles, or book suggestions would be appreciated.
