HS-7 powder question

[Miata Mike]

I picked up a pound of HS-7 powder today along with a lot of other stuff, and was wondering that exactly this powder might really be good in? I think the guy may have used it in .44 magnum, but I'm really not sure.

The price was right for all of the stuff I got.

It should be pretty close to AA#7 or Blue Dot. A little slower than HS-6. I'd try it in .357 Magnum and in hot 9mm loads.

I like 2400 in .357, but I am open to other choices. Keep 'em coming.

HS-7 is the same as W571 but unfortunately both are discontinued. HS-7 is a great powder for the 10mm and in turn for the 40 S&W.
