WWSD2020: Faxon Heat Stress Test Correction Video

Published on January 18, 2020
Duration: 1:56

This video details a heat stress test on a firearm barrel, specifically examining the impact of rapid firing on shot group consistency. The test involved firing 30 rounds to heat the barrel, followed by a five-shot group to assess any shift in accuracy. The results indicated that while the group size expanded due to heat, the center of the group remained consistent, suggesting proper barrel heat treatment.

Quick Summary

A heat stress test on firearm barrels shows that while shot groups expand due to barrel heat from rapid firing, the center of the group can remain consistent if the barrel's heat treatment is proper, preventing unpredictable shifts.

Frequently Asked Questions

What happens to a firearm's shot group when the barrel gets hot?

During a heat stress test, a firearm's shot group typically expands in size as the barrel heats up from rapid firing. However, the center of the group often remains consistent, indicating proper barrel heat treatment.

How does barrel heat treatment affect accuracy under stress?

Proper barrel heat treatment is crucial for maintaining accuracy under stress. It ensures that the barrel does not shift its point of impact unpredictably when heated, even if the overall group size increases.

Which barrel brands performed well in the heat stress test?

Both Faxon Firearms and Ballistic Advantage barrels performed well in the heat stress test. They demonstrated that while groups expanded with heat, the point of impact remained stable, suggesting good heat treatment.
