Hi gei,
I have taken two Cape Buffalo with my Merkel 470NE, one with Woodliegh softs and one with Woodleigh solids.
I normaly load one soft and one solid but with the buff shot with the softs we were tracking buff with a pride of Lion Just in front of us (one is quite alert when walking through Jesse bush where Lions were just seen) and with the one shot with the solids he was by him self and we had Elephant in the thick bush around us. So the situation at the time will dictate what is best to have in old two pipes.
PS; No need for anything but Woodleighs for a Merkel 470NE to shoot and kill well IMO.
