Bill and his 22/250...
His shooting skills were beyond belief....with any weapon.
Nice wide open field.
You're pretty observant. What does that have to do with anything??
Take any decently constructed 55-60 grain bullets running North of 3000 fps, maybe even North of 3400, poke the critter in the vitals and stuff dies rather quickly. Most will be DRT or if they can handle it they might run 50 feet at the most.
Speed kills.
