Since there hasn't been much talk on this, I figured I would revive this thread.
I gave the frog lube a try here last week. I have been on the regular CLP train for lube a long time. I know in cold weather, you are supposed to use a LIGHT amount of oil sparingly. I can see where Mobil1 would excel here. I still haven't given this a try, and I haven't snubbed this off either. I will do it someday. Anyways, I keep hearing jibber jabber about this froglube, and nobody knows if it "works" in cold weather. To some people cold is -10, to others it is -40. I want to give this a go in some real nasty weather, but inshallah, the weather was not co-operating with this greasy half-ginger bearded caveman.
I put a generous amount of frog lube on the buffer spring, buffer, bolt carrier, bolt, cam pin, and locking lugs, ensuring I kept the face of the bolt clean. I cycled the action of my Bushmaster (Yes, Bushmaster. I don't own a DD or KAC, but I can still shoot folks. Let the hating begin.) to get the froglube all over the place. Mind you I did a good detailed cleaning, and made sure I got rid of as much of the old carbon and dirty carcinogen CLP that I could. I locked her up as per, and placed her for 24hrs inside my unheated garage. Range day came. It was only -16, but ice was forming on the old 'stouche, and the hands that have been frost-bitten so many times hurt like hell. Thats a good sign I suppose. I hit the outdoor range and didn't do any real planned drills, just confirmation of zero, some work at 100m, then snap shooting at 50m and closer on multiple targets, mag changes, transitions to secondary, Moving and shooting, etc. Before I started shooting, I slowly racked the action trying to feel if anything was freezing up, but old shrubby was still slicky smooth. I was surprised. I am pretty skeptical about new fandangled things. Shooting went well, I didn't pound 1k rounds through or anything, but the only stoppages I had were the expected empty mags. I did about 200 rounds tops, but can't complain about how the froglube performed.
Cleaning afterwards, wipedown was easy, carbon came off with the same amount of scrubbing, It doesn't appear to "cut" the carbon any better/worse than CLP, but for cleaning your bore, I would stick to your usual cleaning solvents, the tried, tested, true stuff. When things start to get REAL nasty and cold, I will give this a go again, and see what happens. I want to see if it will fail in the -30 to -40 celcius range.
Hope this was a little educational for folks.
