Re: H-870? Thought it was gone
I think you excavated a dinosaur bone with a little meat left on it. Don't get crazy beating the bushes for more of it because it hasn't been manufactured for several years. I bought a pound of H870 several or more years ago, unknowing that it was out of production, but it didn't do anything that other similar propellants wouldn't . I buy powders that are replaceable just in case it "dots the i".
