Anyone out there having trouble with their Ruger American??? I have the standard stainless model and it started out pretty decent, little over an inch with good reloads, nothing formal just kind of sighted it in and it shot right around an inch or so. Don't really shoot it much, but it seems to have gotten worse over the last several months. Same ammo, same scope. Borescope shows barrel is clean, never really did ever foul. Groups opened to almost 4" shot off a Sinclair rest. Thought I found it, it had a cracked scope ring. Now it will shoot very impressive groups {like .375" or so} but the point of impact keeps dancing around. It will put two touching then jump right and high, put two touching there and go left. Maybe the scope??? I installed a Timney trigger at 1 1/2 pounds. The stock screws are tight, rings and bases are fine. It seems like it's trying to shoot. Never really had a rifle jump around like this.
