264- is this the same .243 that you're limited to factory loads for deer hunting? If so, I don't think the Barnes Originals are available in loaded ammo so the 115 gr. bullet isn't an option. Or have you decided to start handloading? If that's the case and you want to use one bullet for deer and elk I'd recommend a Barnes X or 100 gr. Nosler Partition as an adequate deer/ marginal elk bullet. I've shot a lot of deer and antelope with a 6mm Rem. and it's always worked but I wouldn't deliberately take it elk hunting.
