.30/30: cast bullets and IMR 4320

[BlueMoon]

I have used the 4320 with a 30/30 just like you, with 173grn lead gc'd bullets. The data is just about the same as 4064 or 4895 with 30.0-32.0 grns giving around 2000fps. Even down to 28.0grns for a little less velocity. My rifle likes the hard cast bullets around 2000fps for accuracy.
