The average distance from which most rifle users shoot at their target is 100-150 yards approximately. A 300 yard distance is considered long for normal hunting/shooting activities. This is why the scope you use for 300 yards will need some special features to enable you to take that long range shot perfectly.
3 Basic Components for a Long Range Scope to Consider
Here are basic components which you need to look for while shooting from 300 Yards:
1. Optimal Magnification
First, long range scopes have greater magnification than others. Optimal magnification is essential for a good shot as it gives you a clear image of the target. “Greater magnification”, however, does not mean too much magnification as the latter comes with problems of is own. It narrows the field of vision for the shooter and decreases the exit pupil making it hard to spot your target in the dark. The best magnification is that which gives you a good solid view of your target. On average a 4x-6x magnification is best for long ranger shooting, depending on how big or small your target is and what the lighting conditions are.

2. Diameter of Objective Lens
Secondly, the diameter of the objective lens on your scope matters. The objective lens is the bigger lens placed at the end of your scope. Its job is to gather light and redirect it to the ocular lens (at the start of the scope, from where the hunter sees) so that you can see your target in plenty of light. Objective lenses are quite useful in low-light conditions where the shooter needs to see their target clearly, e.g. when shooting deer in the woods at dawn or dusk. Larger objective lenses attract more light and are better for shooting targets at a distance. However, too much light can also be a hindrance as it will too much for the eye to take in during good natural light such as in the morning. It also entails a bigger objective lens which adds to the weight of the overall scope. A 32mm-40mm objective lens is best for long range shooting such as at 300 yards. It provides you with ample light and a wide enough field of view.
3. Glass Quality of Lens and Its Coating
Lastly, you should focus on the glass quality of the lens and the lens coating. High density, low dispersion glass gives the best image. Investing in a scope with good quality glass lenses will take you further than a cheaper, low-quality scope would. Next, the lens coating is just as important as the quality of the ends. When the objective lens gathers light from the surroundings, some of it reflects off of its surface resulting in a loss of light. This is why most manufacturers put a thin chemical coat on the lens which helps reduce the loss of light. Fully multi-coated lenses are great for long range shooting as they minimize the loss of light up to 92% approximately.
