that would freak me out if bears came to where i was deer hunting. But Ive killed a chipmunk with my Tippman model 98 custom paintball gun before. it was kinda of an accident because it was just standing there and my buddy knowing im a hunter said why dont I shoot it and Ijust for fun I sent a couple paintballs over at it and when I went to look at it it was there dead as a doornail. a paintball must have hit it in the head and killed it as for as I can guess.. (ohh yea that was all skill and no luck by the way)
