How well is your rifle shooting ? Then we have something to go on. Also if you surf over Graybeards you will find referance to 7/08 from Gunsmithing colum, Savage and so on , just to give you some idea what others are going with this round.
I have never heard of anyone bedding the action, replacing triggers, lapping the Lugs , as you might well do with one of the other brands .How is the crown ?Is the scope good and the rings and mount tight ?
Then too what ammo are you feeding this gun ? If reloads what was the factory Ammo shooting in this gun ?
My '06 was shooting close to 2" with some reloads and this bothered of coarse . But trying different ammo I soon discovered it was starting to like one brand better . Then too I must have been getting used to the gun , for the rifle as well as Myself sure started to get the act together after a few box's fired .
I use a foam cleaner then patch the bore . The only other thing thing done to the rifle is load and shoot.
So if your getting 1!/2 groups from the start , that's fair, try another brand. and so on. Got to work abit with Ammo.
