But, this totally ignores the fact that some of the lighter for caliber bullets, like the Barnes, hit with more energy, penetrate deeper, and shoot flatter than A-frames and partitions; all with less recoil.If a Lioness is the biggest DG you intend hunting, buy a 375 H&H.
If you plan on hunting larger DG(Tuskless elephant and Buff), buy a 404 JEFF.
Stick to heavy for caliber bullets when hunting in Africa(eg. 300gr and up to 380gr in .375 and 400gr and up to 450gr in .404) and you will be just fine. Too many folks want to shoot lighter bullets at faster speeds which is not what these calibres where designed to do. 2200 to 2400 ftps is more than enough for optimum performance with heavy for calibre bullets.
For instance, in 416 rem mag: My 400gr A-frame load vs my 350gr TSX load = the 350gr TSX hits with 300 ft/lbs more energy @ 200 yds than the A-Frame, and unlike the A-frame, retains 98-100% of its weight.
Why go with a heavier A-Frame when it is ballistically and terminally inferior to a lighter bullet of different construction?
