Take the 270 with 150 Nosler Partitions,it will kill the little stuff as well as anything. I know a guy who used one of these bullets to kill two bull elk very dead so it'll work on anything on which you don't want to use the 375.
The only problem is that it will most likely put a big exit hole in a dead leopard,but that's where a good taxidermist comes in handy.
I know that Utah mountain lions and leopards are different critters but my friend Wade Lemon says that the 270 is one of the quickest killers and best choices on cougars and he has taken as many as anybody.
