WW Ball Powder 531

What cartridges or calibers is this ball powder used for when reloading?
I can't find any data searching the net. Would you help, please?

Are you sure you're not mistaking it for WW231 powder. I can't recall ever seeing a WW531.

231 is a favorite for 45 acp.

I've never heard of 531.

Just spoke with the owner who is gifting powder to me. He's unsure of the number will let me know today. Thanks for those of your helping determine what I have.

NOw I uderstand why it wasnt found. It is Ball powder 571 used for light pistol loads and shotguns in the 20 and 28 gauge. No longer manufactured.

Any idea of how old this particular canister of powder is? I would open it when you get it and smell it, if you get an acidic smell, it would probably be best to either burn it (outside) or sprinkle it on your lawn like fertilizer, I wouldn't take a chance with it.

If it smells ok, load some rounds and shoot them. Here's some loads lifted from a Cast Boolits forum posting (2009):

Several places on internet says WW571 is same as HS-7. I called Hodgdon Powder ans asked if this was true. "NO" was answer. Technician said different data for both powder. Shotgunworld.com also says WW540 is same as HS-6. Again, Hodgdon representative said no.

Thanks Ron for the reloading information. I pick up the powder on Thursday Ill let you all know what I get. If sour i pour it on the lawn for fertilizer.

P{icked up my powder clean as a whistle no odor and it came accompanied with a card board keg of Red dot.

Wow, great deal. Red Dot is versatile also.

Hi,

I may have some old Winchester booklets around somewhere that might give us an idea when production of 571 ceased. Off the top of my head and before I look, I want to say mid-'80s.

Winchester #14 from 1994 lists 571 as a currently produced powder in their lineup. #15 in 1997 no longer shows it as being able to be ordered although that manual still has the load data for 571. Their 1999 manual omits all 571 data.

I used this powder in the late 80's-early 90's for loading 38 Spl and light 357 Mag loads with cast bullets. My original data had shown it was an ccurate powder plus being clean burning. Again my records show that I switched over when 231 became available.

Hi,

Thanks for looking it up! My manuals are quite buried right now...

I use to use 571 in my mag. 1 1/2oz 12ga loads. And 540 for the 1 1/4oz mags

Here`s a good read on SGW on 571
