One thing I learned the hard way is that you gotta take those airbguns down and clean them and tighten them up right. I mean everything! At least as far as you are comfortable. You probably have loose screws somewhere. And those jokers will come unbelievably dirty from the factory.
Next you should find some ammo if likes. If you are shooting that high velocity super stuff then it may be why you are flinging shots. Crosman and Benjamin pellets are usually pretty good but for the best results you may want to try a bunch of diffferrnt pellets with different weights and see what works best in your air rifle.
I learned on a lot of the various gear you may buy it's generally a good idea to take it down, look it over, and clean it up/out like you would do any firearm.
