Do you know whats in there?

Hello, everyone. Now I enjoy mixing up experimental batches of bullet lube as much as some of you guys..but there could be a possible danger of bore corrosion..Santa brought me Paul Mathews latest book on Black Powder Bullet Lubes. He states that long ago, he used water-pump grease on breech-block of original Sharps carbine..hot saopy water clean-up & carefully oiled..later found rust in bore. Used same water-pump grease in smokeless lube..cleaned with Hoppe's & oiled..caught rust just in time..some unknown ingredient in grease reacted with heat/pressure in bore?
I see alot of posted lubes containing commercial oils or grease of unknown make-up. Just a heads up.

some greases like older soda (sodium)or lime (calacium) grease will have some water in them as well as clay greases most other soaps are pretty dry

sodium stearate.
calcium stearate.
those names sure sound familiar...

I continue to have anxiety over the hygroscopic properties of Sodium Stearate in boolit lube, but through repeated, long-term testing and not cleaning bores for long periods between shooting, and copper-strip testing, I simply cannot prove that it is a concern in a wax-based lube. Stearic ACID, however, will rot barrels, gas checks, brass, and tools.

So yes, fair warning to all lube cooks: Use your head, some things change properties when exposed to heat, friction, pressure, and smokeless powder residue.

i'm gonna go with water pump grease being a bentonite [bentone] based grease.
good for friction modification and a good barrier grease too.
but it's open air water property's not soo good.
