Ok I'll bite - nice cover - however I'd always see things more simple - for me there are only elephant guns and others...while I can stand the pressure with buffalo being close with my 9.3 in my hand, elephants realy knock the proportions out of perception...I mean being close to those brutes and feel, hear and finaly see how tons are moving 3 meters above the ground without any predictions is damn scary and I guess something in .450 or more would make me feel a bit easier (not much tho...) - so to cut it short - I don't have a clue how much is enough but getting a grip on pucker factor is important!
