I just make sure I hear it hit the target or backstop which is easy with how quiet they are. That is one benefit of the metal backstop (it's angled down 45 degrees), but makes a "ding" even when I miss the spinners or when it passes through the paper targets. I am in no way recommending their use in a rifle, but just giving my personal experience. With that said I will only buy the Supers if I go back to Colibri's, but will primarily use the CB Longs from now on. This has everything to do with accuracy though.
I used CB LONGS to hunt tree rats-the kind that love acorns. More thump that the pellet gun.
