Well, I've been using automotive grease without any problems. The heavy wheel bearing grease is pretty viscous and sticks like hell.

A buddy of mine has some special grease he ordered from somewhere. I don't see that it is a bit better, except that it came in something like a hypodermic syringe so you can squirt it into the recesses. He usually gets it all over everything. I just use a toothpick to dab a little on my guns.

Hope this isn't too much of a faux pas! Back in these Virginia hills we have to make do with what's on hand.
