Well....switched out guns and went back to killing birds dependably. Something changed because this gun used to throw shot exactly where I looked. I've had several unexplained misses lately (which were very troubling). Shot my 28 today and killed everything I pointed it at, and I think I've figured it out....my face changed. My wife's been stress baking lately (& I'm eating very well on this vacation) and...I've gained weight. I shoot left and when I cheek the gun it throws right now.
