The speaker, demonstrating practical knowledge, subjects the all-polymer magazines to rigorous abuse, including drops in dirt, impacts on steel, and being stepped on. Despite their budget price and lack of metal inserts, the AC Unity magazines perform surprisingly well in live-fire tests, making them a viable option for range use or as backup magazines.

This video from Civilian Tactical reviews the incredibly volatile Havok Halo rounds from Hickory Flat Boars. The host demonstrates their high reactivity, showing a smoking crater in dirt and significant charring/melting in a ballistic gelatin test. A strong warning is issued about the fire hazard these rounds pose, especially in dry conditions, due to intense sparks and heat upon impact with hard targets. The host's expertise is evident in his handling and safety demonstrations.

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.
