Heck DO IT !! if thats what you want someone to say. I mean you admit your already broke and can't buy a muzzleloader so you took it upon yourself to just hunt with a shotgun, are you just taking one shell with you ?
I am messing with you, dont do it, in Indiana if you got caught this is what you'd get
Hunting without permission
Trespassing
if you shot a deer then Poaching
your deer would be taken
you'd have a class D misdemenor on your record for life
I would stay out, plus if someone sees you, or you kill a deer and it runs onto someones backyard your just going to make hunters and bow hunters look bad.
