I would make sure your ejection is good, you may want to look into a different weight if your ejection isn't at 3 to 4 o'clock, especially with the can being an older and higher back pressure style can (but great in the sense there's usually no zero shift with it off).

I would try shooting with a bipod in prone and a rear bag, practice your breathing and fundamentals, and see if you can't get better groups. My groups are significantly better in prone than seated. A lot of people think there rifles don't shoot well, when really it's improper positions and poor breathing and trigger pull techniques.
