7.5 Swiss. Ran out of IMR 4064... IMR 4320 just as good??

[soloban]

I've been using 44 Gr of IMR 4064 in my 7.5 Swiss reloads with 168 Gr SMKs or 167 Gr Lapua Scenars with great results. Unfortunately I just ran out of IMR 4064 with five cases to go. I went ahead and reloaded the last five with 45 Gr of IMR 4320 to try to approximate the same velocity.

I've got 1 1/2 lbs of IMR 4320 on the shelf that I had purchased for 7.62x54R, anyone have results good, bad, or other otherwise with IMR 4320? Would be nice to know for when I shoot off this current batch. BTW, I'm shooting a K31.

Thanks in advance!
