Surplus WC852-

I've use a bit of WC 852. The issue with it is that it had varied quite a bit in burning speed, depending on the lot. Jeff Bartlett sold a bunch of it on his website. There were 3 burning speeds. Fast lots were close to H-335, Medium lot (which is what I have) is close to H-380 and slow lots were very near 4831 speed. I bought mine from Jeff Bartlett who was very knowledgeable on the subject.

You will need to determine what speed your lot is.

WC-852 was loaded in M2 30/06 ammo.

The surplus powders for 223 & 308 are WC844 ( H-335) & WC846 (BLC-2). I've shot some WC-844 and it is very close to H-335. Those two powders could also vary from lot to lot, but not as much as the WC 852 did.
