Hands down…..I would use the air rifle.
There is an old cemetery in town. An early morning visit will have you seeing a hundred of them roaming around. Amazing mess of squirrels and it is absolutely no hunting allowed. I always wanted to sneak in there with my air rifle and pop a few.
I don’t shoot the ones that hang in my yard. Thems is dog toys. She howls and carries on as they go from limb to limb. Once across the fence she kind of gives up on them.
That pup sure has you excited to get you some more tails.
