Do you think that it would be safe to make a couple of coyote getters in 12 ga.?? If you're not familiar with them, a coyote getter is a fixed position gun with a bit of meat attached to a trip wire, a yote shows up to eat it, pulls on it, then it fires, usually a .38 blank loaded with cyanide into their mouth, but I want to make one with a 12 ga shell instead. Do you think it would work???
