Scope Problem explored...
Posted by Murphy on Apr 18 2005
Burton,
Are you trying some kind of gizzmo bore sighting aparatus to "sight in" your rifle?! Shame on you! Mount the scope and place the rifle on a stable (sand bag) position, look through the barrel at a target or a spot on the wall in the house, and move the cross hair (reticle) to that point. You can actually cut notches in a card board box to rest the rifle for the house part. Then go to the range and lay the rifle on sand bags or some stable rest and do the adjustment again while looking through the bore at a target then shoot the rifle three times at this target 25 yards away. Adjust the elevation and windage to center the shots in the twenty five (25) yard target, count clicks, each click is one sixteenth of an inch at 25 yards, then shoot three more.(aim at the center) This would take no more than six (6) shots and you should make sure all bullet holes in the group are in a half inch or less. If this works, you do not have a problem, you have a good scope and a great bear setup. If you cannot adjust the elevation or windage to center your shots, come back and get on your computer and tell us all about it. (Measure how far off the shots are.) Then we will have some useful information to exchange. You CANNOT sight in a rifle with a bore sighter. You may or may not get on the paper with one. You can do the same thing by looking down the bore at a target from a stable, still rifle, then shoot for final adjustment. I have sold and mounted over 1400 Leupold scopes (and many others as well) and this is the technique I always use and it always works. Unless, as is the case on some rare occasion, some thing is wrong with the scope or mounts or rifle. I am so good at this (yes I'm bragging) I do this procedure at 100 yards at a 25 yard bulls eye pistol target, they are 24" square with a six inch bull, and oh, so very rare is it that the shots are not on the paper. By the way, if zeroed at 25 yards, you're on at about 200 yds, depending on the highth above the bore. You have a Ruger M77 with Ruger rings and a Leupold scope. All good, strong equipment.
I have faith in your equipment and I have faith in your ability to do this. Good shootin'.
Murphy
