I've shot 4 five shot groups at 100 and I'm getting about twice as much horizontal as vertical stringing. Before these groups, the scope shifted in the rings so I remounted the scope tightening the rings. Not farmer tight but definitely more than just using the screw driver with my fingers. A little bit of forearm strength this time. Scope has the parallax adjusted to 100 yards. Barrel has been floated and the action bedded. Any help is appreciated.
