Yes, I use air rifles all the time. A .22 air rifle at point blank range to the brain will do just fine.I just seen a video of the broom stick method earlier! actually a few vids. One guy even accidentally pulled its entire head right offMy main fear more than anything is doing it wrong and increasing the suffering. Do you think a .22 Air rifle could do the job quick enough if if it was to the head (point black)? In culling I feel its the physical contact that would hold me back more during the process. It is on the lower end of power about 450 fps
