Found a keg of Win 571 Powder... (HS7) Any useful data?

Hi -

I have been cooped up with my lovely wife, and She Who Must be Obeyed directed some deep excavation. I survived, and on the upside I discovered a 5# can of Winchester 571 powder. It's marked $19.95 on the top.

I see it's the same as HS7. Is anyone using this stuff to push .45 Colt or ACP? or .38/.357. If so any pet load would be appreciated.

Also - I got a .327 Fed Mag. Brass is pricey. Anyone had a source?

Thanks & Stay Healthy!
