Longer-term, if you can create a small clearing in a woodland where the shooting angles are safe, and run a topper over it just once a year (end of Aug/early Sept.) it becomes a 'deer lawn' and will reward you as deer will visit it on a regular basis.
Planting or sawing some Chicory (variety Puna 11 is good) or other plants that are attractive to deer could help, such as red clover, and orchard grass. Certain high-protein crops, such as peas, soybeans, turnips, alfalfa, sorghum and kale will also attract deer.
Be aware that a landowner may not be impressed if you try to attract deer, if your Brief is to reduce the population... (?).
