We have been using Mobile 1 0-40 on a variety of weapons in sub zero temps with good results. We were out yesterday in freezing rain and it worked well at temps in the teens and a lot of moisture.
It looks like it sludges up with the water, but it still seems to properly lube everything.
I ran FP-10 in -25F weather and had no problems. Don't recall round count thou. It worked.
I would imagine SLIP 2000 would be GTG too, but haven't tested it. Well I take that back, maybe down to -5F.
