It should always be considered a unkown powder.Any guesses?
Any guesses?
I have. And it looks very similar to that. Win Autocomp. And off the top of my head, those are both reasonable charge weights. Here's a pic I just took.I've never seen a powder with oddball shaped granules like that
I've never seen HS-6, but per Hodgdon's data, those loads the OP listed would be awful light for HS-6.Looks eerily like hs-6, except for the tear shaped granules.
Fertilizer
Odd. Perhaps Auto Comp really IS floor sweepings.I have Auto Comp and it is more of a flat round flakes,(actually a little different than the previous pic of it)
I didn't say burn it on a manhole cover. I guess you guys don't remember the good ole days.
