OK, who's got the skinny on this powder? All I've got so far is this: http://loaddata.com/articles/PDF/New%20Powder%20From%20Hodgdon.pdf It sounds like just what the doctor ordered for RUMs, AMs, etc. A ball powder with a burning rate somewhere around H870 only it's temperature stable (see the above PDF). Better than the old H870? Make WC872 obsolete? Too good to be true? I get the feeling at least a couple here have used this powder already. Time to spill your guts! Tell us what you can!
