Couple of things:
1. The greatest elephant hunter, Bell, shot most of his elephants with a 7x57. Smaller than a .308. With premium bullets, you can kill anything with a .308. Roy Weatherby used to hunt cape buffalo with his .270 Weatherby to prove it could be done. Patterson, the guy who killed the Tsavo lions, did it with a .303 Enfield.
2. Handloader just did a study that many of the lighter bullets, such as the Accubond, Interbond, Sirrocco and something else, do lost 10-15% more weight when shot over 3000fps. They go from 90+ to 80 if they're lucky.
3. I shot my last desert mule deer at 268 yards lasered (prone off a rest) with a .300 H&H Mag and 200grn Partitions. The meat was just fine.
4. This is my new Weatherby Vanguard that I bought in .338 Win Mag and had rebarreled with a Douglass barrell in .257 Weatherby Mag.
