Bramble-

Thanks for the link.
I've had one full-on seizure of a black rifle in the desert, with the bolt part way back and the action stuffed full of that fine-as-talc dust - from a hard fall and the rifle ending up ejection port side first between me and the earth.

Ended up needing to slide-hammer the thing into the ground butt-first with my boot heel against the charging handle to get it free.
That dust is nasty.
Hosed it down with water from a camelbak and kept running it.

I wasn't kidding about the gin.
It actually works - and it doesn't attract silt/dirt/dust/sand.
Makes a refreshing beverage too.

Cheers
