	Tj3006; Are you SURE that you want to shim the front mount? That will cause the bore axis & the optical axis to diverge. Think of the tang sights or military ladder sights. The further the target, the higher the peep climbs on the rear sight. That makes the bore & the optical axis converge closer to the muzzle. Which is usually what is desired. Of course, those Remington model 7's are odd little beasts. 900F

	shims go under the rear. think of the scope as being solid, and the rifle doing the moving (not vice-versa as you were). if you shim the rear (and the scope is solid), it shoves the muzzle-end up.
	Hunting is not a matter of life or death; it is much more important than that.

	I see what you mean I went the wrong direction Darn The front of the base is bigger and I,ll have to cut the shims smaller and there is only 1 screw !I would rather have the shim beetween two screws but I,ll just have to redo the job. ...tj3006

	Ok I redid the shim job and I think it will be fine, I don't knoe if I used enough shim. I put .008 inces of brass shim,under the rear of the mount ing base. If that does not do th job, Ill have to look for some thicker shim stock, I don't want to use more than 2 pieces stacked. ...tj3006

	You might try finding out why the scope needs to be shimmed. Is this the first scope on that rifle? What kind of scope and is the scope new? what mounts are you using? Do you have a shot saver? did you center up the adjustments before you started? Is the barrel floated? If you have a shotsaver you can loosen the rings a little and twist the scope 180 degrees and see if the crosshairs are still in the same place on the shotsaver screen. If they are not it probably is the scope. You may find that the barrel has too much contact with the stock at the forearm end. Also check the barrel crown visually and with your finger nail. Usually these kind of problems are a process of eliminating possibilities. If all this don't work take 2 aspirins and go to bed. Dan

	I had to do that with an old Model 88, with tip off mounts, but then I put straight Weavers on it and it was fine without the shims. It wore the shims for about 10 yrs with no problems. Also I ahd a Weatherby that specs said to use remington bases on it. I had the same problem and used shims. But you do want to set your elevation and windage adjustments in the center of the range before proceding That way you have maximum adjustments each way when you are finished.
