Duration: 11:52

This video details a ballistic gel test of Colt branded .45 ACP 185-grain solid copper hollow-point ammunition. The test utilized two 1911 pistols with different barrel lengths (4.25-inch Taurus Commander and 5-inch Rock Island) to evaluate performance. Results showed significant differences in bullet expansion and penetration based on barrel length, with the longer barrel yielding better expansion.

Quick Summary

A ballistic gel test of Colt .45 ACP 185-grain solid copper hollow-point ammunition showed that barrel length significantly impacts expansion. A 5-inch barrel achieved excellent expansion and 14-inch penetration, while a 4.25-inch barrel resulted in no expansion and deeper penetration (16-21 inches).

Frequently Asked Questions

What were the key findings from the Colt .45 ACP ballistic gel test?

The test revealed that barrel length significantly impacts the expansion of Colt .45 ACP 185-grain solid copper hollow points. A 5-inch barrel promoted excellent expansion and a 14-inch penetration, while a 4.25-inch barrel resulted in no expansion and deeper penetration (16-21 inches).

How did the barrel length affect the velocity of the Colt .45 ACP ammunition?

The 5-inch barrel Rock Island 1911 achieved a higher average velocity of 1132 FPS compared to the 4.25-inch barrel Taurus Commander, which averaged 1079 FPS. This velocity difference likely contributed to the expansion observed with the longer barrel.

Did the Colt .45 ACP ammunition retain its weight after firing?

Yes, all recovered projectiles, whether expanded or unexpanded, retained their full weight. The weights measured were consistently between 184.3 and 185.1 grains, indicating robust construction.

What were the expanded and unexpanded diameters of the Colt .45 ACP projectiles?

The unexpanded projectiles measured the standard .451 inches. The projectile that expanded successfully from the 5-inch barrel measured between 0.837 and 0.88 inches in diameter, demonstrating significant expansion.
