I was recently willed a charles daly 45. My family really wants me to carry it when I bow hunt.?

I bow hunt bears and they are convinced I will get eaten someday. Any way I would like to know what the best ammo to feed this thing. It came with a couple boxes of wolf fmjs. They cycle fine and the gun has never jamed even after lots of quad dust. The point is I know way more about arrows than 45 acp. I want a round that cycles good shoots accuratly and has more knock down power. I know from my limited rifle expierence that hollow points have alot more umpth! I hound hunt coons and bobcat and use a cci 22 hollow piont. Nothing else works.
