The noticed velocity from the four-inch barrel of the revolver was barely decrease than the producer’s printed figures, whereas the rifle skilled considerably larger velocities. This variation highlights the impact of barrel size on the ammunition’s ballistic efficiency.
Recoil Expertise
Recoil was current and noticeable within the revolver, however manageable. Within the rifle, recoil was much less pronounced as a result of platform’s design. The skilled recoil is typical for a .357 Magnum load, which provides a stability of energy and shootability.
Penetration and Terminal Ballistics
Penetration ends in the ballistic gelatin have been noteworthy. The JSP bullets achieved a decent depth of penetration, offering indication of the spherical’s potential to achieve very important organs. The rounds carried out nicely by way of terminal ballistics as nicely.
The JSP bullets demonstrated efficient growth throughout the gelatin. The growth generated a considerable wound channel, additional enhancing the potential of the ammunition to cease a menace. The bullet retained a excessive proportion of its unique weight after impression, which is indicative of fine efficiency.
Reliability Findings
No malfunctions have been noticed all through the testing. The ammunition confirmed a stage of reliability, and the primers fired persistently.
