Duration: 5:00

This video demonstrates the impact of cold temperatures on ammunition velocity. By testing Norma Oryx, Federal Power-Shok, and Remington Core-Lokt rounds after freezing, the experiment reveals significant velocity drops in standard ammunition compared to Norma's temperature-insensitive offerings. The findings highlight the importance of ammunition choice for consistent performance in extreme weather hunting scenarios.

Quick Summary

Cold weather significantly impacts ammunition velocity due to less energetic powder and increased air resistance. Norma offers temperature-insensitive ammunition designed for consistent performance, showing minimal velocity loss in freezing tests compared to standard brands like Federal and Remington.

Frequently Asked Questions

How does cold weather affect firearm ammunition velocity?

Cold weather reduces ammunition velocity because the powder is less energetic and the air becomes denser, creating more resistance. This means the bullet starts slower and encounters more drag downrange, impacting ballistic performance.

What makes some ammunition more temperature stable than others?

Temperature-stable ammunition utilizes powders, propellants, and primers specifically formulated to react less drastically to extreme cold or heat. This ensures more consistent burn rates and, consequently, more predictable velocities.

Which ammunition brands performed best in cold weather tests?

In this test, Norma's ammunition demonstrated superior temperature stability, maintaining significantly higher velocities when frozen compared to standard offerings from Federal and Remington.

What is the typical velocity drop for standard ammunition in cold weather?

Standard ammunition, like Federal Power-Shok and Remington Core-Lokt tested here, can experience velocity drops of around 20-30 meters per second (approximately 65-100 feet per second) when fired from freezing temperatures.
