Straight between the eyes is a bad idea with a raccoon, whatever the small calibre projectile being used. If you're hitting a raccoon with a .38" or 9mm at 800fps or faster a hit straight between the eyes is probably going to penetrate the thick bone there which is at an angle prone to deflecting anything weaker. If you want to take out a raccoon (I have no reason to do so, but understand the need in some circumstances) your best bet is minimum 30fpe and a shot from the side into the brain, somewhere like halfway between eye and ear hole (bottom of the ear). The exact desired point of impact will of course vary with your available perspective on the thing's head. Front shots are generally considered wrong among those who dispatch raccoons as part of their professional work. Same applies to bears and quite a few other critters. But if you look up the story of the biggest bear killed at its time (record since broken, but it stood for many years), the woman shot it with a bolt action .22lr, just where I describe, between eye and ear. She was an experienced trapper, knew where the brain would be as well as the weak spot in the skull, and followed up with a bunch more hits within a 2" to 3" circle there just to be sure - this was a defensive shooting, she had no real choice left.
