Plains game, I would go with the 270grain projectiles, I prefer the Woodleigh PP's. This makes them a bit flatter shooting than the 300grainers. I would also have 5 loaded with the Hydrostatict in case you need a solid. In all my rifles that I have Hydros loaded for they shoot to the same POI as the soft nose I use.

I too would recommend Karl as John has.I have hunted with them twice and have been well looked after. I also have heard good reports about Komas Safaris? Spelling could be out. I would google a few and see what their clients have to say about them. Also it depends on the type of hunting you want to do.
