I recently added a scope to my 40x .22, in hopes of improving accuracy over the opens (my eyes are getting old). At the range today, the temps were -9 degrees, and I think I was getting irregular ignition because of it. My first shot (Federal 36gr hps) hit about a foot low. Had to use nearly all the UP in the scope's adjustments to get on paper, then it was up/down/left/right - never could get a cosistent POI, even when I switched to Remington/Eley Club Xtra. A quick glimpse down the bore to double check found "smoke" in the bore to the point that I couldn't see through. Like black powder shooters, I had to blow the smoke out to clear it. Needless to say, the bore and reticle weren't even close. Never had that happen before, but then I don't think I've ever tried to shoot rimfires in those temps before, either. Anyone else experience this phenomena with your rimfires?
