RE: Antler shed traps?
I read an article on something similar. They put posts in the ground in the shape of a V or W and then they put chickenwire on it. With whatever bait, food or whatever is legal in your area they put it in the middle of the " V" when the deer bent down to eat it they scraped their antlers on the chicken wire, if it was time for them to come off they fell right there.
Also seen a picture of my buddies 3-D target in the spring that had an antler stuck into it. Apparently some buck still had a little fight left in him.
