I reecently cleaned my cousins old Mod. 700 BDL in 30-06. He said it used to shoot very good with factory ammo. Then all of a sudden it just started slinging bullets everywhere. Problem is that he never cleaned the bore of the rifle, just the outside of the gun. After a very thouough cleaning of the bore he said it shoots better that it ever did. It did take a lot of cleaning, but that did the trick.
