Do hunting regulations affect scope choices for competition?

Scope Size and Power

When selecting a scope for competition hunting, it’s essential to consider the maximum power allowed by regulations. In the US, for example, the National Rifle Association (NRA) High Power Rifle competition has a maximum power of 12x for scopes. This means that shooters must choose a scope that is either 12x or lower to comply with the rules. A 12x scope can provide sufficient magnification for accurate shooting at long ranges, but may not be suitable for shorter ranges where faster target acquisition is necessary.

Objective Lens Size and Weight

Regulations may also affect the choice of objective lens size and weight, particularly in varmint and small caliber competitions where the overall weight of the rifle is a factor. A smaller objective lens, such as a 30mm or 36mm lens, can be beneficial in these situations as it reduces the overall weight of the scope and allows for a more compact rifle design. However, a smaller objective lens may also reduce the scope’s ability to gather light, potentially affecting performance in low-light conditions.

Parallax Adjustment

Regulations may also impact the choice of parallax adjustment type, particularly in competitions where the rifle is allowed to be adjusted for parallax during the competition. A parallax adjustment that allows for quick and easy adjustments, such as a side-adjustment parallax or a parallax adjustment with a zero-stop, can be beneficial in these situations. However, a more complex parallax adjustment may be more suitable for competitions where the rifle is not allowed to be adjusted for parallax during the competition.
