What is a Brush Gun? Part 2

Published on September 9, 2017
Duration: 21:18

This video tests various rifle calibers to determine their effectiveness when shooting through brush. The key takeaway is that heavier, slower bullets (like .44 Magnum or .577/450 Martini-Henry) are less prone to deflection and tumbling than lighter, faster rounds (like 7.62x39mm or .30-30 Winchester). Mass is identified as the most critical factor for a reliable brush gun.

Quick Summary

Bullet mass is the most critical factor for a reliable brush gun. Heavier bullets (180+ grains) with lower velocities are less likely to deflect or tumble when hitting brush, ensuring better accuracy compared to lighter, faster rounds.

Frequently Asked Questions

What is the most important factor for a brush gun's performance?

The most critical factor for a reliable brush gun is bullet mass. Heavier bullets, ideally 180 grains or more, combined with lower velocities, are significantly less likely to deflect or tumble when encountering brush compared to lighter, faster projectiles.

Which calibers performed best when shooting through brush in the test?

Calibers with high bullet mass performed best. The .44 Magnum (240gr), .30-06 Springfield (220gr), 12 Gauge slugs, and especially the massive .577/450 Martini-Henry (600gr) showed minimal deflection and maintained accuracy through dense brush.

Which calibers struggled when shooting through brush?

Lighter and faster calibers like the 7.62x39mm (154gr) and .30-30 Winchester (170gr) were more susceptible to deflection and tumbling when hitting brush. The .30-30 even experienced bullet separation on a thick branch.

What is 'keyholing' and why is it relevant for brush guns?

Keyholing occurs when a bullet tumbles and strikes a target sideways, creating an oval hole. This indicates a loss of stable spin, often caused by deflection from brush, leading to drastically reduced accuracy and making it a sign of poor brush gun performance.
