Re: DNZ scope mounts

Are there any situations that "require" or prefer to have the scope mounted higher ? Or beyond a certain distance ?

Re: DNZ scope mounts

The only two I can think of are to clear a large objective lens at the front and to add clearance over the action if the rifle ejects the case into the scope. Early sniper scopes were on high mounts to clear the strait bolt handles on military rifles. Not a factor for modern guns.

Really low mounting can make it hard to get your head down behind the scope if the cheek of the rifle stock is too high. But it is better to get a proper fit on the stock than raise the rings.

Re: DNZ scope mounts

If you haven't already done so, give the article "fitting the long range rifle" a good read. The issue of cheek weld is covered very well. How high your scope is mounted above bore is a factor which is more determined by the size of the objective bell and the contour of the barrel than anything else. We generally like to keep things as low as possible without those two parts touching each other, in order to avoid needing to raise the cheekpiece of the stock any higher than necessary to achieve clear sight picture. Sight height is a field in any good ballistic program because it is part of the geometry that must be calculated into the drop chart. The performance of the load doesn't change when you change scope height, but your viewpoint when taking the shot does. Play around with your ballistic program's sight height setting and compare drops at longer distances in the output to see what I mean. Kennibear's comments on cant are spot on: no matter how high or low you mount the scope, you need to keep the rig plumb or your shots will be thrown wide of the mark. I use a tool that rests on the barrel and the scope bell at the same time to install the scope plumb above bore, and install an anti-cant level at the same time. The eye and the inner ear can play tricks on you in the field, but a properly installed bubble level will not lie.
