This video explains the 'Speed Drop' technique, a method developed by Accuracy First for rapid target engagement at varying distances. It involves calculating a 'gun number' by subtracting dope from range and then adjusting scope turrets or using a simplified hold based on this number. The technique aims to allow shooters to quickly acquire targets without extensive range estimation or dialing for each shot.

Quick Summary

The Speed Drop technique, developed by Accuracy First, is a method for rapid target engagement. It involves calculating a 'gun number' by subtracting your rifle's dope from the target range and adjusting for an error margin. This number simplifies holds, allowing for faster shooting by either dialing the scope or using a simplified subtraction from the range.

Frequently Asked Questions

What is the primary purpose of the Speed Drop technique in shooting?

The Speed Drop technique is designed for rapid target engagement. Its main purpose is to simplify the process of holding for different distances by calculating a specific 'gun number' that can be dialed or used as a simplified holdover, allowing for faster target acquisition.

How is the 'gun number' or Speed Drop number calculated?

The 'gun number' is calculated by first determining your rifle's dope for various ranges. You then subtract this dope value from the target range (converted to decimal form). The most common resulting number is then adjusted by subtracting an acceptable error margin (e.g., +/- 0.2 mils) to establish the final Speed Drop number.

What are the recommended tools for calculating Speed Drop?

The video mentions using ballistic calculators like the Applied Ballistics Kestrel device or the Ford Off app. These tools help in accurately determining the dope and ballistic solutions necessary for calculating the Speed Drop number.

How can shooters with scopes that don't dial below zero utilize the Speed Drop technique?

For scopes without sufficient downward adjustment, shooters can dial off the decimal portion of their Speed Drop number below zero (e.g., 0.3 mils if the number is 2.3). They then subtract the whole number part (e.g., 2) from the target range to determine their hold.

Who developed the Speed Drop technique?

The Speed Drop technique was developed by Accuracy First, an organization founded by Todd Hotnet and his son Colby Hotnet. They have created videos and features related to this method.
