Air Temp
 

I recently found both my springers shooting to a new point of aim. Blamed one on a "barrel set" from setting against the wall in the garage. But then the one that hangs horizontally in the basement without support under the barrel did the same thing. I noticed that it was happening when the weather was cooler, high humidity, around 30- 40F. Seems air density has an affect on point of pellet strike. Anyone else observe this?
