Do These Bullets Suck?

This video tests the performance of 1-karat diamond-tipped .45 ACP rounds fired from a 1911. The tests included a water jug penetration and a ballistics gelatin test. The diamond-tipped rounds, similar to FMJ, did not exhibit expansion and passed through both water jugs and the gelatin block cleanly, suggesting potential underperformance compared to traditional hollow points in this specific configuration. The presenter questions the effectiveness of .45 ACP hollow points in general based on these results.

Quick Summary

In tests with 1-karat diamond-tipped .45 ACP rounds, the bullets did not expand in water or ballistics gelatin, behaving like FMJ. They pierced through water jugs and gelatin cleanly, leading to questions about the general effectiveness of .45 Auto hollow points.

Frequently Asked Questions

How do diamond-tipped bullets perform in terminal ballistics tests?

In this test, 1-karat diamond-tipped .45 ACP rounds did not expand in water or ballistics gelatin, piercing through cleanly like FMJ ammunition. This suggests they may not offer the same terminal effects as traditional expanding hollow-point bullets.

Did the diamond-tipped .45 ACP bullets expand in the water jug test?

No, the diamond-tipped .45 ACP bullets did not expand in the water jug test. They created a crack in the jug and passed through, exhibiting behavior more akin to Full Metal Jacket (FMJ) projectiles rather than expanding hollow points.

What was the performance of .45 ACP hollow points in ballistics gelatin according to this video?

The video's tests indicated that .45 ACP hollow points, including the diamond-tipped variants, did not expand in ballistics gelatin. They passed straight through both water jugs and the gelatin block, leading the presenter to question the general effectiveness of .45 Auto hollow points.

Are diamond-tipped bullets more expensive than regular ammunition?

Yes, even artificial lab-grown 1-karat diamonds are expensive, making diamond-tipped ammunition significantly more costly than standard bullets. The video highlights this cost factor in its introduction.
