A-Frame then Accubond but either should work just fine.
I have to admit all of my African animals fell to Barnes out of 300 H&H, 375 H&H, and 404 Jeffery.
The Barnes outshot the Partition and GMX out of the 300.
Barnes outshot the GMX out of the 375.
Barnes outshot the A-Frame out of the 404.
I would shoot the A-Frames and Accubonds in 180 and 200gr weights and go with what your rifle likes.
