Great start for the winter season. Always good to get a baseline. I assume you will track your scores over the season to watch the improvement.
One suggestion would be to put a small table/tv tray in front of you to hold the pellets. Each shot you are breaking position to take the step over and back to get another pellet. So your footing and natural point of aim needs reestablished each shot. Having pellets within reach will help be keeping the NPOA consistent. I just use a tv tray and set it in front of me when I get ready to shoot. Then fd it up and put it out of the way when I’m done.
Great job and keep the lead flying.
