between 4064 - 4320 - 4350. I have wondered if I should have tried to find out how close to 4350 it is/was.

Oh Well. I'm sad to see it go but I won't have a void.

IMR4320 isn't nearly as slow-burning as IMR4350, and in fact is almost identical in burn-rate to IMR4064. You can find this out easily by looking at Hodgdon's on-line data. Rarely will maximum charges of 4320 and 4064 vary more than a grain in the same application, and often they'll be even closer.
