Leopard Expert Trophy (45)
Take down the Leopard Trophy in Safari Hunt on Expert Mode.

When you happen to get to the Leopard level, firstly equip the .375 rifle. Then go north straight away and after a short while you will see a very big hill slightly on the left, your crosshairs are probably starting to turn red at this point. Get to the top of the hill and use the sniper to look directly forward, and a little to the right, zooming in all the way. You should see a leopard far in the far distance walking towards the rocks & trees to the right of the screen.
