Rugged Rifle Scopes

Most of today’s modern sighting scopes feature important elevation and windage adjustments that are carefully referenced by the minute of angle (MOA). The single click of a scope turret alone is just a quarter of an MOA change. Some scopes sport about 1/8 MOA. Shooters of every type normally refer to such adjustments as changes considered for a 100-yard distance at a fraction of an inch rather than the real MOA value that they are built to calibrate.

Even the inch difference is a simple number to work and everyone can easily make out the corresponding length and multiples without relying on a calculator. The comparisons and differences are just close enough for you to be concerned, especially when it only involves just a few hundred yards that corresponds to the real difference of 0.47 inch for a thousand yards. But when it comes to serious target shooting and considering the increase of the distances, taking the minute of value into account regarding careful sight adjustments truly matter.

Calculating the minute of angle is expressed in degrees. Shooters of all types rely on it because it represents stability every time they figure out the elevation and the windage to come up with an exact figure of the distance to the target that must be covered efficiently. Angle measurements are equally important, where its value is easily calculated basing from the source of the origin, which primarily is the muzzle of their rifle barrels. Considering MOA measurements embraces the constants of mathematics, man’s universal language.

Everyone knows that rifle scopes has a standard and effective precision value based on an inch of a particular distance which also makes calculating the precision other distances much easier, but they are still obliged to get the exact measurement of any distance considered and its corresponding measure in inches. Another way to tackle it is through the angle measurement. This contrast is evident in a certain situation where an expression of 0.73 inch at a distance of a hundred yards is compared to a 0.7 minute of angle. To a shooter’s eyes, both are practically the same, but he is perfectly aware that the expression that employed the MOA calculation is more concise because distances are not included.

In a long range situation where distances considerably vary, the smart thing any expert would do is knowing at heart the value behind each actual scope adjustment. This can be especially handy when scope settings are being changed and adjusted out in the field as the shooting distances also change. Not all scopes however are fortunately calibrated using the minute of angle or considering measurements by the inch in a precise manner. In the cases of the more powerful rifles with their explosive punch, it is highly recommended that targets be determined at no less than a hundred yard distance as some of the widely used projectiles today can prove to be unstable at much shorter distances, which ultimately gives a false impression of true performance. Even the MOA consideration won’t matter in this situation.
