RE: i feel ashamed guys...
What ever floats your boat! If you can't get a thrill about hunting then it may be time to hang it up. You can make gun hunting anything you want it to be just like bow hunting. You can set parameters in your hunting i.e.; not taking a shot over a certain yardage, not shooting a certain size of animal, or using a more primitive weapon for examples, but their should be no reason to feel upset about taking an animal as long as it's legal. Maybe you have these feelings because you didn't challenge "yourself" enough!
