Hey guys im new to this whole thing. But anyways i have a Ruger 77/22 mag all weather edition rifle with a leapold 2-7x32 powered scope on top held down by some ruger rings. I bought this gun used. The problem is i cant get a grouping better than 2 inches and thats off a benchrest at 100 yards! So i took it to the gun shop down the street to have the crowing checked but we came to the conclusion that my scope paralex was messed up so we adjusted that. Next day took it out and no luck! Plz tell me what could be wrong with this gun!
