I won't comment on the lethality and effectivenes of 160gr Partitions, because that has already been proven.
My factory 7mm Mag (Savage 110) shoots MOA at book speeds/loads (I lucked out) both in 150gr and 160gr pills with IMR4831 and RL22 respectively. ~3100 for the 150s and ~3000fps for the 160gr PTs.
160gr PTs, 64gr RL22 Rem 9 1/2 Mag primers WW brass
OAL 3.29"
150gr BTs 60.5gr IMR4831, Rem 9 1/2, WW brass
OAL 3.33"
I have not tried other primers or powder since I don't see the need.
I will vouch for 160gr Sierra Gamekings shooting very close to POI, though they can stand a bit more powder than the 160 PTs.
They kill whitetails very well too.
