Quick Answer
To adjust for bullet drop in variable optics, use the ballistic reticle and estimate the bullet drop from your ballistic calculator or range card, then use the reticle's subtensions to dial in the correct elevation. Start with a known distance and adjust from there. Practice makes perfect.
Understanding Ballistic Reticles
When using a ballistic reticle, it’s essential to understand the subtensions and markings on the reticle. A typical ballistic reticle has a series of hash marks or dots that indicate bullet drop and wind deflection. For example, a 4-16x variable optic might have a subtension of 1/4 MOA per click on the elevation dial. This means that for every click, the point of aim will be raised or lowered by 1/4 MOA. To adjust for bullet drop, use the reticle’s subtensions to estimate the drop and dial in the correct elevation.
Estimating Bullet Drop
To estimate bullet drop, use a ballistic calculator or range card to determine the drop for a given distance. For example, at 500 yards with a 30-06 Springfield and a 150-grain bullet, the drop might be around 45 inches. Using the reticle’s subtensions, you can estimate the drop and dial in the correct elevation. In this case, you might need to dial in around 8 full clicks (8 x 1/4 MOA = 2 MOA) to compensate for the bullet drop.
Practical Application
When adjusting for bullet drop, start with a known distance and adjust from there. Use the reticle’s subtensions to estimate the drop and dial in the correct elevation. It’s also essential to practice adjusting for bullet drop in a safe and controlled environment, such as a shooting range. Practice with different distances, angles, and wind deflections to become proficient in adjusting for bullet drop. Remember to always use a ballistic calculator or range card to determine the correct drop, and to double-check your adjustments with a spotter or rangefinder.
