RE: 43 degrees makes a difference.
MLKeith, Try tightening the lugs to the barrel of the Omega. I read a post where someone had a rifle that started spraying randomly, they found the mounting screws on the lugs loose. After tightening everything back up the rifle was a good shooter again. I told my brother and he found the screws loose on his Encore. Of course I have always thoughtmy bro hada screw loose.
