Emcon5, your experience with the 511 is highly out of character for that series. That is the first I have ever heard of a 5xx series that wouldn't shoot good. I wonder what was wrong with it.
I did have one time with my 512 when the bullets started flying. After checking, I found that the front stock screw had come loose. After tightening it back up, it resumed shooting great. Sometimes, it can be something very simple that makes a rifle go wonky.
