WC 845 Surplus Powder???

[ArchAngelCD]

OK, I have loaded countless pounds of WC844 in the .223/5.56mm and I know WC846 is for loading the .308/7.62mm but when did WC845 show up? Is it right in between WC844 and WC846 or something different? It's listed as meant for the .223/.308 so I'm guessing it is right in between the other two powders.

Anyone use it yet?

It is listed as used in the M995 AP 5.56 round. (light projectile)

Have not used that one personally, just WC844.
