1. Position a vice with padded jaws on a sturdy table near a wall.
2. Clamp the rifle in the vice level both ways and with the breech pointing at the wall (bolt removed).
3. Shine a small flashlight down the muzzle towards the wall and place a vertical strip of masking tape about two feet long where the dot of light lands.
4. Using a large spirit level and black marker draw a true vertical line on the masking tape that passes through the dot of light (mark that dot on the tape with a cross in biro).
5. Centre the reticule in the scope by using the mirror method (press the objective lens to a mirror in a brightly lit room and adjust cross hair so it overlays its shadow).
6. Clamp the scope in the rings with a small spirit level balanced on the top of the elevation turret to ensure it is horizontal left to right.
7. Shine a powerful flashlight through the front of the scope and turn the focus ring until the reticule is in focus projected on the masking tape.
8. If the scope is aligned with the bore in the left to right axis you should see the crosshair intersect with the vertical line on the tape.
9. If the cross hair is on or below the biro mark then the mounting rail has useful tilt built into it.
10. If it is above the biro mark by the distance in which the scope centreline is above the bore then the mounting rail has no tilt.
11. If it is above the biro mark by more than the distance in which the scope centreline is above the bore then the mounting rail has the wrong kind of tilt.
Aye Ken, I did ....and back in 2007 too!
Funny how this thread has popped up again... but all the methods still pertinent today as it was then.
Wondering whilst Wandering pays dividends! Thanks all!
