I know absolutely nothing about air rifles. Would a .22 pellet be effective for a possum or groundhog at <25 yards?
As said, it will depend somewhat on the rifle, but I have in the past killed several whistle pigs at that range with a medium powered spring-air .22. It also depends on shot placement, a larger one is pretty tough to kill quickly except with a headshot. A higher powered PCP .22 can provide twice the power of my old springer.
