GoPro 6 Audio Test Sound Quality / S7

This YouTube video performs a zoom test on the GoPro 6, evaluating video quality at 1080p and 2.7K resolutions. The focus is on how well the camera captures detail when zooming in, providing a visual demonstration of its capabilities for various recording scenarios. The description highlights the testing of different zoom levels and resolutions.

This video compares the terminal performance of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The test demonstrates a significant increase in destructive power from .22LR up to .45 ACP, with the larger calibers causing more explosive expansion and fragmentation. Specific hollow-point ammunition from Speer, Aguila, and Underwood was used, highlighting the importance of bullet construction for terminal ballistics.

Buckeye Ballistics conducted a comparative test of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating significant firearm and ballistics knowledge, emphasized extreme safety precautions due to ricochet risks. The test revealed that while larger calibers showed more damage, none could fully penetrate the concrete block's second wall, suggesting limitations for self-defense scenarios against hardened barriers.

This Taurus TX22 review details its performance with various .22 LR ammunition. While initially reliable with CCI Mini-Mags and cycling standard velocity rounds well, it encountered malfunctions with sub-sonic and high-velocity loads. A catastrophic failure occurred due to a squib load followed by a second shot, resulting in a bulged barrel and damaged magazine.

This video compares the terminal ballistics of .22LR, .22WMR, and .17HMR rimfire cartridges using cantaloupes as targets. The .22LR showed a clean pass-through with minor damage, the .22WMR caused an explosive front-face disintegration, and the .17HMR, despite its speed, disintegrated internally with no exit. The test highlights how different rimfire rounds perform on soft tissue simulants.
