Thanks for getting my hopes up... Kynamco dashed them without delay. They are sold out of the NfB 500 Express ammo and will not be making more. The demand was slow (although they sold out) and the corporate decision is not to go there anymore.

I asked if they would share the recipe and they told me that the powder they used was "blended" for them in England and was not available to reloaders.

The specs were quite impressive. 440 grain soft jacket bullet at 1,900 fps... that's a stout load, enough for nearly anything I'd like to shoot with this gun.

I'll go it on my own, after over 45 years of reloading I am certain that I can get this job done.
