Rifle Scope Testing
We are able to test your scope to see that it functions as expected.
This involves testing all the functions of the scope.
- Magnification Control
- Parallax adjustment
- Illumination controls
- Bench Rest Box Test for dialing
Probably the most important test is the bench rest box test of the scopes ability to dial and return to zero.
Some people do a ‘box test’ by shooting at a target however this has issues as you have a number of factors to deal with, wind, your shooting, ammo, the rifle so to be sure its correct, you really need to shoot quite a number of rounds with can be both time consuming and expensive.
By mounting the scope to a solid bench we are able to isolate the scope from any rifle, mounts and person so we can monitor just the scope without any external factors.
This gives you confidence and could save you ammunition and a wasted trip to the range.
“If you need to adjust the scope by a precise amount in order to account for gravity drop on a long range shot, it’s imperative that you know exactly how much your crosshairs actually move when you turn the knobs. Simply assuming that each click is what it’s advertised to be is a bad policy, and will cause misses at long range. What’s worse, this problem can erode a shooter’s confidence in his firing solution, and leave him guessing about how much to adjust his sights.” – Bryan Litz
Tests done overseas have shown that even high end scopes can have some error in their total adjustment.
If you are considering long range shooting; then you will have heard of the Correction factor that you apply in Ballistic software to calibrate the software to what your scope actually does. Under the paid version we finely check the dialing and report the observed error (if any) across the full range of the scopes dialing. This of course takes a lot more time than the box test and we need a decent day (lighting wise) to do it as well.
For us to do this, we need to of course open the box and also attach rings to the scope so we can mount the scope to our bench test. With this comes a small chance of a cosmetic mark from the rings. We always use high quality rings to ensure they fit properly.
