I had the same toughts about 8 years ago, but have religated my small pistol cross bow (40#draw)to a last ditch thing. I did use it to a few take Ptarmigan while on a long outing, but then they are fairly stupid birds and are easy to kill with a thrown rock or stick. I tried for a few rabbits and snow shoe hare with it but the 40# pistol is a little slow for either one. I though of trying a heavier draw but never got around to it. I still keep it around because it will be better than nothing at all, but personally won't use it until I run out of ammo.
