Having only shot ONE leopard, I'm far from an expert but I used a 150g Hornady Interlock on my Tom. Muzzle Velocity was 2,787 fps. Shot was only 62 yards. Leopard was facing away and standing at the base of the bait tree. The bullet went entered through the shoulders and exited the right armpit.
BangFlop.
I suspect your accubond load would work just fine.
As others have stated. They aren't hard to kill. It's just a shot you really don't want to mess up. That's more important than your bullet choice. Any good deer bullet ought to work fine.
