Duration: 7:53

This video provides a detailed comparison between the 350 Legend and 450 Bushmaster cartridges, focusing on their performance against steel targets. The host, demonstrating high expertise through empirical testing, uses a custom 'Steel Sled V3' target holder and chronograph data to analyze impact velocity and penetration. The results highlight that while the 450 Bushmaster has higher muzzle energy, the 350 Legend's higher impact velocity at certain ranges can lead to superior penetration on specific steel thicknesses.

Quick Summary

The 350 Legend demonstrated superior penetration against 1/4 inch mild steel compared to the 450 Bushmaster, achieving clean penetration where the latter only caused a dent. This highlights the importance of impact velocity (around 2100 fps needed for 1/4" steel) over raw muzzle energy for specific penetration tasks.

Frequently Asked Questions

How does the 350 Legend perform against steel compared to the 450 Bushmaster?

In tests against 1/4 inch mild steel, the 350 Legend penetrated cleanly, while the 450 Bushmaster only created a significant dent. This suggests impact velocity can be more critical than muzzle energy for penetration in certain scenarios. Both failed to penetrate 3/8 inch mild steel.

What factors determine steel penetration for rifle cartridges?

Impact velocity appears to be a critical factor, with a minimum of around 2100 fps suggested for penetrating 1/4 inch mild steel. While muzzle energy is important, the velocity at the point of impact, influenced by ballistic coefficient and distance, plays a significant role in penetration capability.

What equipment was used to test the 350 Legend and 450 Bushmaster on steel?

The test utilized a custom 'Steel Sled V3' target holder designed for steel plate testing, equipped with a capture system and neodymium magnets. A chronograph was used to accurately measure muzzle velocity for both cartridges.

Are 350 Legend and 450 Bushmaster effective for steel targets?

Performance varies significantly with steel thickness. The 350 Legend showed better penetration on thinner (1/4 inch) mild steel due to higher impact velocity, while neither cartridge penetrated thicker (3/8 inch) mild steel. Results depend heavily on the specific steel and range.
