Rx11?

[49willys]

My 1970 Lyman manual has a powder listed called Rx11,what is it?Does it have a different name now?

Is it a name for Reloader 11 from Alliant? I'm not sure if that existed but sounds like it anyway.

Is there only one reference to it? It might be a typo.

Probably a misprint of Rx12 (no longer made)
