It didnt do so well in my gun. I actually had some of them fall out between the pellet injector device and the barrel while cocking the gun. Its the only pellet to do that so far (21 different pellets have been tested in my gun to date). The accuracy of that pellet was terrible in my gun: average velocity was 965.66 fps, standard deviation of 2.53 fps, but best group at 20 yards was a whooping 5.48 inches!
