I shoot with a 17 hmr, 22lr and 22 FAC air rifle. I can head shoot bunnys as long as the weathers good, i.e. not to blowy out to 70 yards or so. Its a Logun Gladi8or at about 36 ftlb i think. I can use the lr out to 100 yards - an Anchutz 1417 and the HMR is good out to about 150yds. Its all tools for different jobs. No doubt these ranges can be bettered, but I'm more than happy with them.
