I'll stick my neck out a ways and offer you this advise...
For years I used Zwickee, then switched to the 125 grain Magnus. A friend went over and was shooting the WIDE Magnus, 135 grain heads. He had 10 shot, 10 perfect hits, and ten FAST recoveries with great blood trails.
I now shoot only the wide Magnus on all my game (unless I'm shooting stone points). The only time I go to the 125 grain now is for Cape Buffalo and Water Buffalo.
Some outfitters, mine included, don't want anyone shooting multi-blade heads. I think they are more geared to the replacable blade type when they discourage them, but the multi-blade head does NOT penetrate bone anywhere near as well as the two blade.
I'm headed over for trip number 11, so I have some African miles on my stalking shoes. Take the wide Magnus...
