If you have a problem with pests the size of Porcupines and Red Foxes, an air rifle with 39 to 70 foot pounds of energy (fpe) will drop them like a bad habit. At a distance of 10 yards, the pellet will penetrate approximately an inch into (39 fpe) or go through (70 fpe) a Douglas fir 2 x 12. These air rifles are most accurate with a pellet ranging in weight from 25 grains to 43 grains. Pointed pellets should be avoided because they are known to be a cause of a jammed magazine (except Sumatras). The “magic” pellet is found by balancing the weight of the pellet to the air pressure that the gun puts out; each air rifle has its own personality.
