I would imagine both the 300 gr and 325 gr A Frames would both serve you quite well. I'd be more concerned with the penetration on the Eland than the other two antelope (just do to their size) I can't speak on the 325 gr A Frame in .454, but the 300 gr .429 A Frame has an unusually long shank which really alters "hot" load data(unless you run another cannelure lower on the bullet) as compared to all other 300 gr. .429 bullets...it's actually fairly significant. Just a thought, but my knock on the 300 gr Mag Jacket XTP isn't over expansion, it's under expansion. When I used them in my Raging Bull, they'd shoot through almost anything, but only expanded minimally.
