my first couple of years I did not get a deer, but now I get at least 1 per season.. with my record being 4 last year (2 with rifle, 1 with muzzleloader, 1 with bow). I guess my ratio is about 1 deer in 4 outings. Half the time I hunt public land so I am pretty happy with this ratio.
Got a big buck this year already.. so any more hunting will be with a bow.
