I saw a video not long ago where a woman used a rig that may or may not have been set up for dispatching a rabbit. It looked to be two pieces of angle iron attached to a 4x4 post in a triangle. She carried the rabbit to the device and simply slipped the neck into the vee of the iron and pulled back against the body and legs in a quick motion. I can't find the link again but just as well. Would be rough for some folks to watch I'm sure.
I have one pet rabbit that will never see the chopping block, once they get a name they are off the menu!
That in mind the rest are never handled so they aren't happy to be handled and there natural instinct to freak out takes over when they are picked up. So if you have bee gloves they can save you a lot of pain from scratching if you use them. Hence my thinking about using an air pistol? I would like to spare them the trauma of being rough handled on their way to death. You could just walk up and give them one shot without their knowing what was coming or what ever happened.
Maybe I'm a little over the line, but I don't think any creature needs to endure undue suffering. That's the biggest reason I stopped hunting years ago. I'm not opposed to it and won't say that I'm not going to go tomorrow, but I would prefer not to.
