oh let me tell you how good this thing is. zeroed in really quickly and soon got down to some serious pellet on pellet shooting, it's soooooo consistent it's unreal. i was using h&n's and after swearing by aa pellets for years these take some beating they seemed to pack loads of energy into the target. my dad also tried them in his hw100ks same as mine and was also impressed. if you can get hold of one of these bad boys get one seriously good value and devastatingly accurate bring on the bunnies
