Yes it is an excellent powder especially in the .223 REM. It is pretty much the same as h335. WC 846 is similar to Bl-C2 and WC 852 is the same as H-380. WC 680 is the same as win680 and a hair faster than aa-1680. WC 820 is the same as h-110 or win 296 powder. All are excellent as well as WC 860 (50 cal) and WC 872 (20MM Cannon) I've used all and they are all excellent and a bargain. I used to get it for $64/8lb keg and the 860 and 872 for $32/8lb keg.
