First Fps is dependant on caliber it will be higher in. 177 than in. 22 if they are delivering the same in foot/pounds. Second if your rifle is consistent and accurate then it will easily bring small game to the pot at greater ranges than most shooters are accurate at. In short chronoscope check your rifle regularly and learn all that you can about your rifles point of impact and your ability at ranges ten to thirty yards, practice really does make perfect.
