Dave, are you meaning WC 820? I had some Vietnam era LC carbine ammo that I believe was loaded with 13.0 grains of WC 820. Very fine granules, and did seem to burn cleaner. About the time I figured out what it was, it was no longer readily available. I've only loaded carbine ammo with H110 and WW296 which nowadays apparently, are exactly the same thing. - Bob
