My last racoon kill was with my Ruger77/22mag shot it just behind the front upper leg/shoulder @ 50-55yards from my Upstairs bedroom window. The racoon walked 3 feet and fell over dead. Yotes took care of the rest. I don't see any problem with a .22Lr if place your shot well...! They (Coons) rip the sh_t out of my grass looking for grubs....
I thought it was skunks that tear up the grass for grubs .
