[QUOTE="Augustus, post: 192037, member: 10142"] Jeff, locating the reason for inaccuracy in a rifle can be a painful and sometimes expensive experience, there are a bucketful of possible causes and many times it will be a combination of things. I have found more often than not scopes, rings and how they are set-up are causing the chaos. I have mounted some high end scopes with high end bases and rings and still have trouble. One brand of rings I use must be lapped before they will work with a USO scope because the rings are a little tight and the scope dont bottom out. You can actually see daylight between the scope and the bottom of the ring body, I always lap the rings then bed the scope in them. Base to ring fit can drive you crazy, I have posted about this problem before, also if you are using adjustable bases I feel sorry for you. If this is not the problem it can be a bad barrel, bad bedding, ammo and who knows what else. To illustrate what you are up against, I just finished chasing out a problem on my pet 308.
