Hi my opinion on this subject is that shooting at long ranges is fine if you have the eye to do so. I always shoot at long ranges the longest i shoot at is 75 yards with a 177 air arms s400 sub 12fp and it does the job.I heard that you only need 3fp to kill a bird.I have shoot rabbits at this range and killed them out right.you do not need a bullet rifle to have long range kills.hears a picture of the squirrel i shoot from 72 yards yesterday
