I have zero experience with hunting leopard, and very limited experience with illuminated reticles, which of course makes me an expert on this issue smile (if the smiley does not give it away humour font is in use on previous sentence).

I have really been impressed with my illuminated Nightforce NXS 2.5-10 which is presently mounted on my .375 and will be going with me to Namibia in 2021 (no cats in the hunt plan) Not sure if that fits your thoughts but it would be an easy scope to sell once you were done with it.
