This is 50 cal spotter powder that is available thru surplus vendors. Has anyone tried this powder and What does it burn like?

Hi tsiero,
dont you mean IMR 7828?

No, he means 7383. I haven't tried it, but a distributor told me that it burns pretty dirty. I have had very good luck with WC 872, which seems, in the lot I have, to be just a tad faster than WC 860, although both are very close (and very slow). I'll be interested in the comments from 7383 users.
