I experienced something I've never noticed before today. Hopefully some of you experts out there can help me with an answer. I have a Ruger Single Six in .22LR that I do not shoot often, maybe two range trips 100 rounds total per year. It was my Father's so it's a gun I plan to one day give to my Grandson. Anyhow, the last time I shot it the ambient temp of the range was probably around 70 degrees F. Today, the temp outdoors was single digits (ammo was in back of my truck for hours so it was cold) and the temp at the indoor range was probably less than 40 as the Furnas was not working. The point of impact was about 5 inches low at 15 yards, it was dead on a few months ago. Would the cold temp of the revolver cause this low point of impact, or the cold ammo? Maybe combination of both? Ammo was SK Pistol Match if that makes a difference. Thanks.
