I dont know anyone who has ever killed anything with them. I would only use them for up to a grouse sized critter and it would have to be really close, less than 15 I would say. I had both sizes a while back. And they were really heavy. I would probably not recomend them. I rarely get within ten yards of small critters. The majority of my shots are around 19-22 yards. If you want something with a big wing span, go with the condor, or the smaller judos! Just my .02
