Personally I think both are a little small for those plains game that reach weights over 300-lbs. Yes, that's my humble opinion! I have seen Impala run for over 175 yards with both lungs taken out, those African plans game seldom go bang flop.
I favor the .338 calibers or the .358 calibers for such animals. Also the 30-06 with a 200 grain bullety, why even the .444 Marlin makes a good choice in the brushveld area as your average shot is only 60 to 75 yards.
I would also change my tune about hunting any Leopard with a .260 caliber rifle.........plan nuts!
