If I understand what I've read.... a lot of things factor into a gun's POI on any given day. Humidity, temperature, wind ect.... probably a lot more than we can even think of.
Yeah. We need a few shots to get adjusted, and settled in.
After reading your comments, does anyone of you have a suggestion for people like me that go out to the wood and hunt? I don't go to the back yard and take a few warmup shots (IT'S DARK); and I have not found many Fox Squirrels that are willing to hang around for me to take a couple warmup shots.
