Anyone used any of these?

I just bought a Smith 686 the guy shot IPSC with, and he mentioned that he used Tetra lube in the barrel, "supposed to protect (whatever that means, my comment) for 2000 shots according to the US Army." I dunno. Never used it, just asking for any other first hand experiences.

A few years back, I met one of the chemists that work for Tetra at the SHOT Show. A very knowledgeable young woman that really knew about gun maintenance products. She demonstrated how their product lubricated metal, dried on the surface and did not collect dust. Tetra products are supposed to penetrate the metal to help protect. Don't know if that would work in the bore for 2000 shots, but maybe. Tetra products are pretty good.

I don't use it in the bore but it's all use on raceways and lugs etc. very thin coat I work the shit out of them wipe the excess. Seems to work just fine.

Used it ~18 years ago. Smells bad. Gun still smells after 18 years => maybe it is very well bonded to metal.

I have used the middle weight one for years;
it looks like milk. After cleaning a shotgun bore and patching it dry, I put the Tetragun on
a patch and work it through the bore well, and
then put a dry patch through the bore to remove
most of it. This seems to leave a light film of
the Tetragun in the bore and fills the small
pores in the steel, so that cleaning the next
time is much quicker and easier. I have done the same with handguns, but have not tried it on rifles. I believe there is some Teflon in
it and don't know if it would affect accuracy.

I have also used the grease on shotgun bolts
and slides, as recommended to me by the Benelli factory rep. , and it worked well.

This is my experience anyway. Good luck.

I used it a bit years ago, and had to give it because of the horrible smell.

I find that there are far too many claims being made for this sort of stuff, which we can never really correlate.

In a gun worshop, one quickly finds what actually works and what does not, and tends to stick to it.

We get so many different types of oils and greases brought here by many people. Some are supposed to perform magic.

They never do.

Of course, some work better than others.

"Penetrate the metal" come on you should know better. It may penetrate into a somewhat porous oxide coating but that's all. That was one purpose of the phosphate coating of the past ,like manganese phosphate.
Smell ? I haven't studied all the smells available but one distinct smell is with some high pressure greases like those found on hypoid gears on a car . That smell was found on RIG +P grease which was made for early stainless steel guns and O/U shotgun hinge pins.
