Reply To: cold weather air gun hunting?
Though you seem to have found your problem, keep the lubes you use in mind when it comes to bitter cold temps. I do alot of late season hunting and had a similar issue as you. It ended up being the lube I had used on the trigger parts and hammer didn’t like the cold. The hammer was actually slowed down creating low velocity and drastic POI change. I switched to polishing everything as much as possible and only using a light spray of silicone spray. Problem solved, but had me baffled for awhile!!
