It's very strange, the OP asks about which of two different bullets he should use for moose, and almost everyone jumps right in and immediately suggests eveything but what the OP asked about.
Maybe these two are what he has to use, and he is not interested in trying any of the other available.
Anyway, My personal choice would be the 140 Partition....because.. It will shoot right through a moose broadside without any problems. [did it personally at least 3 times] and it will stabilize in a 9 twist barrel, whereas the 160 may not.
If you are shooting an old military type Swede rifle, the twist will be 7.8", and it will handle those 160's just fine.
