Thanks guys, I will have to buy the bullets(240gr XTP .430diam) and Harvester Crush sabots separate to make the combination.
I have found also a distributer locally with who I placed an order for their 340gr bullets in .50cal,

Feedback from a few fellow-hunters are that their bullets are much cheaper than those from oversea and they shoot very accurate from most inliners.
My rifle will be setup for warthog which is quite a tough species to kill even with a centre-fire rifle, so I guess the 240grXTP will be a little on the light side.
