That is a 301 IBO speed bow. Compared to the newer bows today, it is relatively slow. As important as the draw weight and IBO speed of the bow is your draw length. The longer your draw length, the less poundage you need for the same KE and Momentum. Figure you will want at least 40 Ft-LBS for warthog and other medium game. The recommended minimum arrow weight would be 400 grain, but I would advise a minimum of 450 grain so that you can go after larger game if you can muster the draw weight necessary (not that hard). You will want at least 60 Ft-LBS and 450 grain arrow for large game (aside from the really big stuff, like giraffe, hippo, etc, that is a real chore to take down and beyond the ability of that bow).
Get me your draw length and I can probably figure out about what you would need to pull back to down them.
