I rabbit hunt without dogs a lot. Find some woods near a corn field. Drive the edge of the woods, or walk the edge of the corn field for a while. You'll jump some bunnies.

Someone else posted a strategy once for hunting rabbits with a .22: Walk an open area where you know there are rabbits. When you jump one, freeze. The rabbit will run about 20 feet and freeze. Take all the time you need to aim, 'cause he'll sit there frozen for a while.

I didn't know this would work, then, one day in my yard, I scared a rabbit. Actually, it startled me too. Anyway, I froze, the rabbit ran a little and stopped. I just stood there and looked at him for about 20 - 30 seconds. I finally stomped my feet to get him to run away.
