I would have zero reserves on using the .300H&H on Eland, and if legal on Lion. My personal experience shows that Lions are easier to put down than Eland. With the correct bullet for the cause, you could even stretch it to Giraffe, where a projectile such as a Barnes TSX or TTSX is used.
The .300H&H is a great caliber and will get the job done on any plains game hunt, and some.
Take Care,
