I'm a bit outside my depth with this critter. Customer dropped off a christensen arms .375 ultramag and he want's me to work up loads, find factory ammo, and get him some ballistics numbers. That wouldn't be a problem... except... He is going to go shoot an elephant with it. I've never hunted elephant. Never shot one. So, can anyone give some advice here on bullet selection for some reloads as well as some factory ammo options? Preferably someone that knows what it takes to kill an elephant.
