I did a comparison test with Crosman Premier hollow points, domed ultra magnums and JSB 18's using my Taipan Veteran .22 standard\LW barrel. Each group is 10 shots off my knee not benched @ 25yds. I shot the Crosman's back to back but the JSB's required 360 degrees of heavier HSA, to achieve 870fps, same as the Crosman's. I've long since known JSB's shoot better in all of my guns but for the money just used for informal target and plinking I'm pleased with their consistancy in this gun, the domes work quite well in my Streamline and the 7.9 .177's do well in my Wolverine, how do the Crosman's work for you and what do us use them for?
