I'm waiting until October 1st then I am going to go after a few critters with my cold steel big bore blowgun I got from sportsmans... Not sure as to legality where you live though... But might be a thought! My dad lives in another state but he has shot several chipmunks and they have died rather quickly! I have been making darts with shishkibob skewers tipped with a x-acto Blade and I'm pretty sure it's going to be hell on squirrels so I'm sure it would work on rabbits... They are pretty thin skinned.. Heart shot you should be golden,.. As long as they don't run in the neighbors yard after you shoot them anyway. Cold steel still makes a broadhead for them just not a razor tipped one anymore.. But the broadhead penetrates awesome and when you hit something soft like the side of the rabbit the orange tip comes off and the metal dart goes all the way through... YouTube hunting rabbits with blowguns.. Tim wells and his buddy buck shoot a couple but they seem to run a little ways.. Practice and do head shots and you should be fine... As long as its legal? I have had a blast practicing with mine and can't wait to hunt small game with it
