Good grief, It's a damn pine goat, not a Cape Buffalo.
Any hunting bullet in the 120 to 150 gr range works just fine to kill em. I've used the 139 gr Hornady Interlock and the 140 gr Partition to kill several dozen deer with my 7x57. Probably half were DRT and the rest ran a short distance. The 7 08 doesn't produce enough velocity to over stress any hunting bullets.
