I have an FAC air plus a standard springer, but I will always use 22lr or 17hmr where circumstances permit, because they have more umph and dispatch more reliably. When you are out to do a job of vermin control you need to do it efficiently. What is the point of having a weapon out of your cabinet that is good to 60 yds when up pops a critter at 110yrds. Need to get the job done and not continually regret lost opportunities.
