My son is out hunting them in the fresh snow right now. If you have fresh snow, just go up in the woods and find some tracks, then take your time and track them until you see them. He is using a 22 pistol.
Around here they like Blackberry brush, or Scotchbroom. Find a farmers field with Blackberry bushes in it or around it, and you will have rabbits. We use 410's. I guess a 20 guage with light loads would be the next choice. We use the largest choke possible, as most of the shots are running, and very quick and close. Buddy of mine used to have the "toy" size beagles, now THAT was a blast!
Then, after you clean and eat them, save the carcasses/hides/guts for coyote bait. I just put it all in a 3 gallon bucket in the freezer and when it gets about 1/3 to 1/2 full, I put enough water in it to make a 3/4 full bucket, and let it freeze solid. Then pick a spot that you can sneak up to within good shooting range from and dump the whole ice/rabbit/etc block out of the bucket. Usually lasts for a couple days that way, depending on weather. If you put it in a ditch, they can't pack it off as easily when it starts to thaw. Then, after it's gone, go back and call. I guess that's off subject, but it works.
