What I do know is that the CP's are available everywhere, cheap and do the job on rock chuck sized critters to around 60 yards in a rifle that is about 100 fps slower than yours. Good enough for me.
Damn, a 14.3 gr pellet going 640fps killing rock chucks at 60 yards... I am surprised- no, absolutely amazed. According to ChairGun, that's got the trajectory of a mortar round and the energy of a Daisy BB gun at the muzzle. Is accuracy OK at that distance?
