You can see my thoughts on those old posts
The Whaley Crosmann was ok if you wanted to shoot tin cans at 30yds, which is what a lot of airgun plinkers wanted back in the late 70s, but for real accuracy you could forget it, the FWBs and BSFs of the day would woop its ass with ease
The reason it sold quite well was the terribly overhyped article and the fact that the public had yet to have access to PCPs
Truth is you couldnt make an accurate rifle out of what was an American toy really, poor quality really did abound and precision was not something remotely connected with that model Crosmann
Probably worth having one in your collection, if only to remind us of how much we wanted a recoiless air rifle back then, ignoring the chewing gum metal and desklid stock
