I have used my 9,3x74R double rifle for plains game on 3 Safaris to Zim, and also one buff with a Swarovski 1.5-6x42 with the illuminated circle dot reticle.
I can recommend that scope and a S&B 1.5-6x42 with illuminated flash dot reticle that I have on a 308.

At 1.5x you have a very wide field of view, at 6x you can make long shots if necessary. The 42mm objective gives you good light gathering for leopard.

Either one of those scopes would be perfect for an African 375H&H.
