I'm going to fix antelope Sniper's post.
WC846=WC844.
Nate, buy a Pressure Trace and you can do anything you want. The problem is 98% of the populace doesn't know what they think they do about powders.
WC846 has an original patent date in the early-mid 1930's. WC844 was a voluntary segregation on an "as-built" basis. There is only one recipe. The difference is based upon 0.25% differences in calcium carbonate. Hodgdon is only, and has only ever been a surplus reseller/blender. Doesn't it strike you funny that they refuse to list nominal burning rate variations?
The question to ask yourself is why it was surplussed. You can't honestly say with a straight face that WC870 = H870. How many different lots did Hodgdon combine and what was the end result burning rate they wanted? Where compared to that goal, is this WC lot you bought?
Buy a Pressure Trace, and you can test pressures yourself.
