Re: WC 872 ball powder
95LTZ
here's a reply from Winchester.
WC872 is a military surplus powder of the ball type. It was made in the old Olin ball powder plant in East Alton, Il or later, in the ball powder plant built by Olin in St. Marks, FL which has changed hands 3 or 4 times in the past 25 years.
Generally, WC872 is a slow burning ball powder, too slow for almost all sporting use. WC872 originally was used in 20mm and 30mm cannons. There is a significant issue with the use of military surplus powder. The burning speed varies a great deal from lot to lot. There is no data for sporting applications unless the seller has the ability to test the powder and tell you what that data is. Most of these sellers do not know what they have so they cannot furnish data. A good rule is to never buy powder from someone who says “Just use data for Hodgdon 870” or “Just use the data for AA8700” This is a sure sign the seller does not have the ability to test their product nor to develop data for their powder.
Surplus powder can be a source of cheap shooting but only if you have some good knowledge of the powder you have purchased.

I think I'll pass on getting some. BTW, my dad was a Semper Fi Marine in WW2. My eyes were only good enough(go figure) to get in the Air Force, but I may have helped some of you out of some hot spots in Viet Nam as a F-4 fighter pilot. Thanks for your service. Holtz
