I did get out today, -9C, heavy snow.
Not sure if it was the high relative humidity, but I had serious fouling issues. 2 shots and it got very hard to load.
Patches saturated with TOW mink oil and I've used them before and could get at least 5-6 shots off before noticing anything, but not today.
In addition, I was shooting like $#@*. Had a couple of warm-up shots, seemed like I was in the ball park, took the first shot at the target and went '#$!?'. After 2 targets, shooting not improving, struggling with fouling and cold weather, I took out the .22 and shot nearly as bad....at 25 meters? Can't recall shooting this bad in a loooong time.
Packed up my gear, hopped over to the rimfire range and spent the next 30 mins just getting my sight picture back and was shooting decent groups at the end. At that point I was too cold and hungry to continue and called it a day.
