I've only shot one leopard, he was baited on the ground, so the 168 gr TTSX bullet from my .300 Weatherby expended most of it's energy in ground behind him. He was dead 19 paces from where I shot him.
The same year that I shot my leopard, I shot a mountain lion that size wise was a twin to my leopard. A 130 gr Sierra FP bullet from my .30-30 killed him instantly.
I've made one shot kills on elk, a red hartebeest, and a blue wildebeest with 160 gr Accubonds from my 7 mm Rem mag.
I would not hesitate to shoot a leopard with my .308 Win and 168 or 180 gr Accubond bullets.
