This video provides an in-depth look at Norma Ammunition's manufacturing processes in Åmotfors, Sweden. It details the creation of copper-jacketed lead-core bullets, the specialized bonding process for Norma Bondstrike rounds, and brass case production. The guide also covers final assembly, rigorous quality control including accuracy testing, and comparative ballistic gel tests, highlighting the performance differences between bonded and non-bonded projectiles.

Quick Summary

Norma Ammunition manufactures bullets using copper cups and lead cores, employing a special bonding process for Bondstrike rounds to ensure high weight retention and controlled expansion. Rigorous quality control includes accuracy tests every 15,000 bullets, aiming for sub-inch groups at 100 meters. Ballistic gel tests compare performance, highlighting differences in expansion and weight retention between bonded and non-bonded designs.

Frequently Asked Questions

How are Norma bullets manufactured?

Norma manufactures bullets starting with copper cups drawn into shape, then filled with lead cores. For bonded bullets like Bondstrike, a thermal/chemical process fuses the core and jacket for enhanced weight retention and controlled expansion. The process involves precise sizing and shaping dies.

What is the significance of ballistic gel testing for ammunition?

Ballistic gel testing simulates tissue impact to evaluate a bullet's terminal performance, including expansion, penetration depth, and weight retention. This helps determine suitability for specific hunting applications, like the comparison between Norma Bondstrike and Hornady ELD-X shown in the video.

What quality control measures does Norma Ammunition employ?

Norma Ammunition conducts accuracy testing every 15,000 bullets, aiming for sub-one-inch groups at 100 meters using specialized test barrels. They also maintain a hand-loading room for new load development and an electronic range for precise measurements.

What are the key differences between Norma Bondstrike and Hornady ELD-X?

The Norma Bondstrike is a bonded bullet designed for deep penetration and high weight retention, ideal for large game. The Hornady ELD-X, shown as a non-bonded alternative, exhibited more fragmentation in ballistic gel, which might be better suited for varmints but less so for preserving meat on larger animals.
