Well, if you want to shoot animals humanely- a camera can't be beaten.

Graphite and MoS2 have the same physical structure (planar sheets of
hexagons) and they work as lubricants because those sheets can slide past
each other.  MoS2 big selling point is that it can work at temperatures
that would cause carbon-based lubricants to burn.

again typically in a grease base.

I have some, both as pure powder, and in a heavy grease base you'll find
it in the drawers of anyone who has worn out the number of rifle barrels
I have at the rifle range, I am also a reloader, and have used up 4
barrels in old meat in the pot. Or AT&T as one of my boys calls it, cuz
it can reach out and touch something. It brought home a nice buck once
from 640 yards. But I haven't tried that again as it was not a quick
kill, no bullet expansion left at that distance so he stood there and
bled to death. He did die right where he was standing but it took too
long, not a humane kill. Lesson learned.

And today I read some warnings during my net searching about it getting
into the cracks and crannies in printed stuff and delaminating it
gradually.  Both that and the finely milled graphites carry the same
warnings, saying don't use. So I'll leave that in my reloading benches
drawer.

Are you concerned that the grease will dissolve the plastic?

Yes.

Cheers, Gene Heskett
