Does A Short Barrel Equal Poor Performance? .38 Special 158 vs 125 Grain Ballistic Gel Test!

Published on October 17, 2021
Duration: 13:48

This video tests the performance of two different weight .38 Special hollow-point rounds (158gr PPU and 125gr Ammo Inc) fired from a short-barreled Taurus 856 revolver into ballistic gel. The test reveals that neither round achieved significant expansion, with both exhibiting substantial penetration. The instructor concludes that the short barrel likely lacks the velocity required for proper hollow-point expansion in these specific loads.

Quick Summary

Testing .38 Special hollow points from a short-barreled Taurus 856 revealed that neither 158gr PPU nor 125gr Ammo Inc rounds achieved significant expansion. The 158gr penetrated 25.25 inches and tumbled, while the 125gr penetrated 19.75 inches with minimal deformation. This suggests short barrels may lack the velocity for reliable hollow-point expansion.

Frequently Asked Questions

Does a short barrel negatively impact .38 Special hollow point performance?

Yes, this test suggests a short barrel (2-inch) on a .38 Special revolver may not provide enough velocity for hollow-point ammunition to reliably expand. Both 158gr and 125gr rounds showed poor expansion, with significant penetration.

What were the velocities of the tested .38 Special rounds from a Taurus 856?

The PPU 158 grain rounds averaged 726 feet per second, while the Ammo Inc 125 grain rounds averaged 814 feet per second when fired from the Taurus 856 revolver.

How did the 158gr and 125gr .38 Special rounds perform in ballistic gel?

The 158gr PPU round penetrated 25.25 inches and tumbled backward without expanding. The 125gr Ammo Inc round penetrated 19.75 inches with minimal jacket peeling but no significant expansion.

Are heavier or lighter .38 Special bullets better for short-barreled revolvers?

This test indicates that neither 158gr nor 125gr hollow points expanded well from a short barrel. While the 125gr had higher velocity, the 158gr offered more penetration. The primary issue appears to be insufficient velocity for expansion regardless of weight.
