All the major, and custom bulletmakers have a range of bullets available, be it softs, solids, monolithics. I'll reiterate that we're hunting Dangerous Game, where the s^*t can hit the fan, and damn quickly. We really ARE fortunate to have such a wide choice available. Whatever we choose, may it be effective, right NOW.
