I shot a bunny years back with a .22lr and watched it run about 20yds with it's head bobbing on the ground stone dead!!!!!
Let's face it bunnies are highly strung creatures
Yep. I see that a lot too. not all do it or do it that you notice . I get some that "swim " their way back down the holes . some areas I shoot have holes all around each other so they have lots of options to get back down below .
