This video details a ballistics gel test of a .308 Winchester cartridge loaded with a 125-grain Speer TNT varmint bullet. The test, conducted from a 16-inch barrel using BLC-2 powder, demonstrates the bullet's extreme fragmentation upon impact, creating a significant wound cavity and achieving approximately 16.5 to 17 inches of penetration. The results highlight the bullet's intended performance as a varmint round designed for rapid expansion and destruction.

Quick Summary

The .308 Winchester 125-grain Speer TNT varmint bullet demonstrates extreme fragmentation in ballistics gel tests, creating a large wound cavity and achieving approximately 16.5-17 inches of penetration. Fired from a 16-inch barrel with BLC-2 powder, it achieved velocities around 3000 fps, with significant weight loss indicating its intended varmint application.

Frequently Asked Questions

What kind of performance can be expected from a 125-grain Speer TNT varmint bullet in .308 Winchester?

The 125-grain Speer TNT varmint bullet in .308 Winchester exhibits extreme fragmentation upon impact with ballistics gel. It creates a significant wound cavity and scatters lead and copper fragments, demonstrating its design for rapid expansion and destruction, typical of varmint rounds.

How does BLC-2 powder perform in a 16-inch .308 barrel for this type of load?

BLC-2 powder is noted to perform well in shorter barrels like a 16-inch .308. In this test, it achieved velocities of 3131 fps and 2941 fps, suggesting it can be a good choice for such platforms, potentially outperforming other powders like Varget in velocity from shorter barrels.

What was the penetration depth and weight retention of the 125-grain Speer TNT bullet in the gel test?

The 125-grain Speer TNT bullet achieved approximately 16.5 to 17 inches of penetration in the ballistics gel. It experienced significant weight loss, with roughly half of its original weight remaining, indicating extreme fragmentation and expansion.

Is the Speer TNT 125-grain bullet suitable for hunting larger game?

The Speer TNT 125-grain bullet is specifically designed as a varmint round. Its extreme fragmentation and rapid expansion make it ideal for small game but generally unsuitable for larger game where deeper, more controlled penetration and less fragmentation are desired.
