Tight screws. Think antelope sniper said that.
.
Recently had a rifle that shot many good groups but one group out of every 3 or 4 confounded me with a 3 inch flier.
In exasperation I tightened the action screws so fargin tight I hurt my fingers just to see if that worked.......
Instant 0.75 moa groups and very consistent.
Buggered if I know.
