Scope and mounts

[falconer1975]

Ok i have messed about with adding shims to the mounts and found strangly that i have it zeroed with shims just under the rear mount, now this in my eyes will point the scope down but it was shooting low is this parlex what what every its called??? and if it is will i not just be able to fit lower mounts to over come the problem? there is about 10mm or so between the front lens and the barrel of the rifle.

Shimming

 

Exactly right.

 

If you shim the rear of the sight you will cause the cross-hairs to point lower, so you will have to raise your aim to hit the target. Basically you just need shim the rear of the sight enough to bring the sight adjustment back to within the screw adjustment, and then adjust to zero on the screw.

 

Conversely, if you were shooting high, and had reached the limit of your screw adjusters, you would shim the front of the sight.

 

Sight height

 

If you are zeroing in at 30 yards, and consistently shooting at that range, the relative height of the sight to the barrel will make no difference. However, shoot at different distances, and the greater the height of the sight to the barrel, the greater the allowance you will have to make for the change in range.

 

I have mounted my sight as close to the barrel as I can, so the adjustments I make for greater or lesser distances are minimised.
