smithrjd,

I guess I'll have to be more specific about the 150-pound/leopard deal.

JKH found standard (not "premium") .243 bullets, like those in Winchester's average factory ammo, to work perfectly on leopards, because they expanded violently and did a lot of interior damage. This knocked the snot out of 150-pound animals. I believe he even really liked the 80-grain "varmint load," though will check on that.

I have found the .243 to be capable on animals much bigger than 150 pounds with bullets such as the 100-grain Nosler Partition.
