I hunt crows from a blind.. I use decoys and a crow call... It depends on the weather.. no wind, light wind...windy day what I will take. Here lately it's been a no to light wind day so I've been using a 177 shooting slugs (does a great job too) if the day is windy I'll roll with a 22 shooting 25.4gr pellets.. I do have some 25cal rifles and have hunted crows with... I personally prefer a 22.. no particular reason other than I just like it..
