Duration: 6:20

This video compares the performance of four Hodgdon powders (H335, CFE223, Varget, BL-C2) in a 16-inch barreled Tavor 7 chambered in .308 Winchester. The testing focuses on velocity loss compared to advertised 24-inch barrel data, using maximum charges with 150-grain FMJBT bullets. CFE223 yielded the highest velocity, while BL-C2 showed the least velocity loss, indicating good performance in short barrels.

Quick Summary

For a 16-inch .308 barrel, CFE223 delivered the highest velocity (2829 fps) with 150-grain bullets. However, BL-C2 showed the least velocity loss (3.8%) compared to advertised 24-inch barrel data, making it excellent for consistent performance in short barrels.

Frequently Asked Questions

What are the best powders for a .308 Winchester in a short 16-inch barrel?

For a 16-inch .308 barrel, CFE223 delivered the highest velocity in testing. However, BL-C2 showed the least velocity loss compared to advertised 24-inch barrel data, indicating excellent consistency and performance in shorter barrels.

How does powder burn rate affect velocity in a short-barreled .308 rifle?

Faster burning powders like H335 can lose more velocity in shorter barrels compared to slower burning powders like BL-C2. While CFE223 provided the highest velocity, BL-C2 demonstrated better efficiency by minimizing velocity loss from its advertised 24-inch barrel performance.

Which .308 powder is best for maximizing velocity from a 16-inch barrel?

Based on testing with 150-grain FMJBT bullets, CFE223 powder yielded the highest velocity (2829 fps) from a 16-inch barrel. This powder is a strong choice if your primary goal is to achieve the maximum possible speed from a short-barreled .308 rifle.

Is BL-C2 a good powder choice for short-barreled .308 Winchester rifles?

Yes, BL-C2 is a highly recommended powder for short-barreled .308 rifles. It exhibited the smallest velocity loss (3.8%) compared to its 24-inch barrel performance, offering consistent and reliable results across various barrel lengths.
