To find the best pellet rifle you must look at some of the specifics. FPS is the measurement of how fast the pellet or bb is going. This is a very important metric because the faster it goes the more penetration the bullet will have into the target. If you are looking to hunt or get game you will need a air rifle with a FPS that is very high and can penetrate deep. The other things to look for is accuracy and a good scope. If the rifle is not accurate you will be unable to hit your target and this will be bad. It doesn’t matter what the FPS is if the shot is off.
