Ive never used mine for deer hunting cause its iilegel in are state but I see no reason why it wouldnt kill a deer I dont think it matters how big a hole is in the deers heart or lungs if its there thats all that matters however I was wondering on the blood trail thats the only part I dont like but if their shot good I guess thats not a real big deal either

If I could I would use a bigger gun though jmo
