FORGET EVERYTHING You've Heard About HOB! Here's The TRUTH!

Duration: 20:26

This video explains the concept of Height Over Bore (HOB) for rifle optics and demonstrates how changing it impacts shooting positions and ballistic calculations. The instructor swaps a higher optic mount for a lower one on a 193 Scala Works rifle, re-zeros it, and updates ballistic data. The key takeaway is that HOB primarily affects shooter position and how data is entered into calculators, not inherent accuracy, and should be chosen based on dominant shooting positions.

Quick Summary

Height Over Bore (HOB) is the distance between the rifle's bore and optic's reticle. It dictates your shooting position: higher HOB aids upright stances on barricades, while lower HOB is ideal for stable prone shooting. Changing HOB requires updating ballistic calculator data, not because accuracy is lost, but to adjust for the new positional reference.

Frequently Asked Questions

What is Height Over Bore (HOB) and why is it important for rifle optics?

Height Over Bore (HOB) is the distance between the rifle's bore center and the optic's reticle center. It's crucial because it affects your shooting position; higher HOB is better for upright stances on barricades, while lower HOB is more comfortable for prone shooting, impacting how you interface with the rifle.

How does changing the optic's Height Over Bore affect accuracy and ballistic data?

Changing HOB doesn't inherently affect accuracy but significantly alters your shooting position. You'll need to update the HOB value in your ballistic calculator to ensure your dope (holdovers and windage) remains accurate for the new setup.

What are the advantages of a higher optic mount versus a lower one?

Higher optic mounts (higher HOB) offer a more upright shooting posture, beneficial for positional shooting like on barricades or tripods. Lower mounts (lower HOB) provide a more stable and comfortable interface for prone shooting, allowing for a better cheek weld and inline alignment.

What are the key features of Scalarworks optic mounts mentioned in the video?

Scalarworks mounts are praised for their self-leveling feature, which aids in scope alignment, and their design for hand-tightening with specific torque settings. They are also noted for their durability and ease of use in field adjustments.
