Tell me all about WC872

What is the good, the bad,..and the ugly about this powder? I have a 300RUM with a 30" tube I would like to get it going as fast as possible. The lightest pill I will be working with will be the 200gr variety,..and will go to the 220 and 240 if need be or just because I can.

Anyone have an opinion or want to tell me why or why not to try this stuff,....the price sure is right. [img]images/icons/smile.gif[/img]

Thanks in advance

Re: Tell me all about WC872

What kind of powder is it and where can you find it? How much is it? I've never heard of it other than on this site.

I've never used it, but it was available at GI brass.com for about 40 bucks for 8 lbs.

Re: Tell me all about WC872

WC872 is a military surplus gun powder originally used for the 20 mm Vulcan. (Cannon powder.) It has a burn rate a little slower than H870. It is temperature sensitive. I have read that it is not good in warm weather and will produce occasional flyers. (DC)

I got mine for $32 for 8 pounds plus shipping, etc.

I really liked it because it produced very good velocity with little to no pressure. The 28 inch barrel probably helped. I was getting a hair less than 3500 fps with 7 mm RUM - 160 grain Nosler Accubonds and could have gone higher. For various reasons I was not shooting too well during this load development and went back to Retumbo.

I am interested to know about H50BMG. It has a burn rate in the same range as WC872 and is a Hodgdon Extreme powder which is supposed to be pretty temperature stable.


I would say Darryl Cassel would be the resident expert to ask about this powder. He has commented on some of my WC872 questions and was very helpful to me.

If you go back to the home page and do a search on WC872 you will find several threads conatining WC872.
