My POC' s weigh around 620-640 grains (finished) with 125 grain points, but I' m concerned about the diameter. My hope it to hunt water buffalo in Australia in the next few years (before I am 40). It' s a bit expensive to say the least, so I want to at least get the equipment together and get familiar with it before the big expense hits. Yep, it will be a Crusader (is there anything else?

).
Arthur, you said what I meant--although I think a fast arrow will go deeper than a spear[X(].
Maybe I am being a bit too apprehensive, but I want to be sure everything is just right for this one--not only do I not want to screw up an once in a lifetime hunt, I want to be sure I ain' t the one that goes toes-up on the deal! (them Aussie buffs are supposed to be very similar to Cape Buffalo--average a hair bigger, with the same temperment).
