Corrections to Elevation

Long-range shots need dialing in elevation and windage, which entails calculating the target distance. You may estimate it or measure it using a range finder.

Then, based on your rifle and ammunition, you’d calculate the bullet drop at that distance – what magnification do you require for the different distances? You adjust the scope’s turrets based on that drop, resulting in the crosshairs being centered on the target at 100 yards.

Turrets and reticles

This should be self-evident. However, you’d be surprised how many rifle scopes have turret adjustments that don’t correspond to the reticle. If you get a mildot reticle, it appears that you’ll also get a mil-based turret adjustment. 

Unfortunately, scopes with MOA-based turret settings are available, which is not what you want. This is especially true with lower-cost long-range scopes. 

Objectives Size

It is one of the most well-known firearms, but it is also relatively unknown. That is, its distinctive profile makes it simple to recognize; nonetheless, many people simply refer to it as “that rifle” and have no idea what it is other than a popular choice in sci-fi films.

The PS90 is a bullpup rifle, which is the first thing you should know about it. This is a sleek, miniature rifle design that has found favor with some weapon aficionados.

The focal plane

Depending on the zoom setting, the reticle marks on a first focal plane sight become larger or smaller. The markers may be far apart when using the largest zoom level, but when using the lowest zoom level, the markings may be close to one another, which may obscure the target and result in erroneous aiming.

The markers do not zoom in and out on optics with the reticle in the second focal plane. At first appearance, this appears to be a superior option; but, there is a huge disadvantage.

The distance between the reticle markers is only suitable for one zoom level. As a result, if you utilize them to correct for height or windage, you must compute the adjustment.


This one change could have a big impact on how your rifle works and how well you shoot. Optics does not replace expertise; rather, it enhances it. The appropriate optic will provide you with a major advantage in a fight, in your immediate surroundings, in competition, and, of course, at home.

If you’re questioning if an optic should be added, it’s time to recognize that high-quality, task-specific optics are best suited to the platform.
