Thread: No 8 wire dialing scope question

One way you can test it without burning through any ammo is to use a bore sighter and dial up and down several times, check at the limits of your adjustment (the markers not the true limit of scope adjustment) if the scope is consistently landing on the same place.

The other option is to clamp the rifle in a shooting cradle or or even an adjustable engineering vice on a portable bench or back of a ute. Get it lined up on a target before locking down the vice or cradle. Whilst locked in, dial in the elevations while looking through the scope. If the crosshairs dial to the correct holdover and then back to the original zero then you can have reasonable confidence in the dial accuracy of the scope.

I had one scope that I could not zero. I mounted it on a spare rail which I clamped in a vice. I tried dialing while looking through the scope. Generally the crosshair would stop moving at about 1/3 of the way from the dial limit and then release and jump as soon as the other dial was dialed out. Dialling and shooting at the range it was impossible to recognise what the problem was. Watching the resultant crosshair movement while dialing gave a very obvious picture in about two minutes.
