The type of pellet makes a difference as well - there are various .177 hollow point pellets (and some .22 pellets) which are very effective against certain pests like squirrels, rats, etc. Between my old .177 Steoger X20 (1000 fps) and my old .177 Gamo Hunter Extreme (forgot what the base FPS was but I remember with PBA pellets, it is rated over 1600 fps - no, that is not a typo) and using hollow point pellets, there wasn't a pest or rodent critter that didn't succumb to a shot within 10-30 yards. My only problem with my Hunter Extreme and why I sold it was it was very heavy (for me anyway) and the break barrel cocking power was pretty intense for my scrawny arms and upper body. PBA pellets are great for rodent stopping power but what you gain in stopping power you take a slight hit in long range accuracy
