My Tikka Superlight is in 270 Winchester. it does not shoot .250 but it shoots 3 shot groups of .75 with Federal Fusion 130 grain ammo,Hornady Whitetail 130 Grain ammo 130 grains ammo shoots .85 Shooting without any fouling from a clean barrel.
I haven,t had any problem with the factory rings as of yet Torqued the ring base to 25 inch pounds and the ring tops to 20 inch pounds.
Handloads might help to decrease the groups but I am happy with the accuracy of the factory loads for the purpose of a hunting rifle for deer out to 400 yards.
I torqued the front and rear stock screws to 35 inch pounds and lowered the trigger pull to 1.5 pounds.
