Just keep the range down to less than 40yds, airgun hunting used to be about fieldcraft, most shots were in the 20-25yd range, I think the improvement in rifle and especially ammunition accuracy these days is convincing people to take longer and longer shots.

We shoot golf balls off a rack down our range at 60yds and a 30mm kill zone bell target at 70yds, but that's from a stable FT style sitting position, not standing, crouching or leaning on a tree.
