WC 680 is the milsurp version of Win 680 and AA 1680. As always, be careful on your workups as milsurp powders can vary a bunch from lot to lot.
My favorite loads in 357AR Max and 357Max use WC 680. It may not get me absolute top velocities, but my PC coated cast bullet loads with it are accurate, consistent and reliable. I have a pretty good stockpile at the moment, but finding WC 680 (instead of the much more costly AA 1680) is more challenging than the more common stuff.
I use it in the 221 Fireball
That is the non-cannister version(even though it comes in a cannister/jug ;-)) of cannister grade Win 680(long discontinued), so star low and work your loads up as burn speeds can vary considerably. 22 hornet, 7.62x39 and 30 carbine are few good uses for it with jacketed.
I use it in subsonic 300 Blackout. Out of the same bbl, 11.7gr WC680 with a pulled Sierra 220gr Matchking and an oal of 2.26" gives 1026fps. 12.1gr AA1680 with the same bullet and bbl gives 1026fps with same accuracy. Primer is Wolf KVB223M. Brass is converted LC 5.56 military. Suppressor is Gemtech Quicksand. I use that load for quiet plinking and killing trapped hogs.
