Posted this before, wade thru it and take what you want, however when it comes to eye dominance and shotguns, this is the guy many of the top “shooters” go to for advice.
More than a little eye dominance issues can be traced back to not really looking at the target/bird, knowing how to look and letting the barrel get in the way.
How many have had a Bird show up unexpectedly, reacted instinctively, shot and the Bird came down....and eye dominance issues magically went away.
