You can, but after a lot of use, full-body deer archery targets get a bit chewed up and aren’t as lifelike. Foam targets can be a bit heavier to move around a field.
However, when the rut is on, deer don’t seem to be overly concerned with all of the details of a decoy and will come into a full-body target.
If you are going to do this, human scent elimination is important. Spray your target with scent killer and add some synthetic buck or doe scent to it, depending on whether your target has antlers or not.
