Thanks for all the information and advise guys. 'Top Predator' yes I was thinking of talking to Mark at Custom Cartridges about loading up some 300gr Woodleighs for me as I'm not set up for reloading yet. I'm from Pukekohe so Mark is only a few hours drive away.If not I'll get some 300gr factory ammo with either Swift A-frame or Failsafe projectiles for this hunt. The outfitter suggested that a 270, 30-06 or 7mm Mag would be fine with Nosler partitions...But I think I'd feel a whole lot happier with my 375HH. I'm really looking forward to this hunt...I'm on a tight budget with a morgage so this will be about as close as I'll get to chasing Buff. Maybe Australia could be on the cards in the future.
