You can get WC 820 from www.gibrass.com and from www.patsreloading.com. I've been using it in .25-20, .357 Max, 7.62x39 and .44 Mag. Works great for me. My batch is identical to AA-9.
There is also WC 820(f) available which is equivalent to HS-7. I've had pretty good results with it and plain based bullets.

I've used a military surplus version, WC 820 in cartridges as small as 7.62 x 39mm and as large as the .30-06 and 8mm Mauser. The results have consistently been excellent: Low pressure and extreme spreads + high accuracy. You should know in advance, however, that different lots of WC 820 have slightly different burning rates. ...Maven

No need to buy virgin/new ball powder! Get the pulldown. Ball powders have the longest shelf life of all of the powders, except those having a nitroglycerin content above 20 percent. Those latter powders are typically the pistol powders faster than Unique, and that strange duck formulation of 5744, "new" lot only. Besides, if I were in an experimenting mood for a brand new powder, I'd select Ramshot Enforcer, a ball powder like the others mentioned here, when found on sale. It's speed should be right in the middle of the #9s and WC820, and would be used for very fine tuning to see if accuracy improves over the 9s, 820s, etc. ... felix
