5.7x28mm VS .22 Magnum

This review tests the effectiveness of suppressing the .17 HMR round. Despite using a Volquartsen VT2 rifle and a suppressor, the high supersonic velocity of the .17 HMR creates a significant sonic crack, rendering it poorly suited for quiet suppression. The test confirms that even with hearing protection, the suppressed .17 HMR remains loud.

Key takeaways include historical context from 1970s magazines and catalogs, insights into cylinder interchangeability issues between older and newer models, and the primary design intent of the Dual Pathfinder as a .22LR firearm with an optional .22 Magnum cylinder.

This YouTube video, "Showing you EVERY Gun- Part 16 PSA 5.7 ROCK," is part of a series aiming to showcase a comprehensive collection of firearms. This specific installment focuses on the PSA 5.7 ROCK pistol. While a detailed description of its content is not provided, the title suggests an in-depth look at this particular handgun, potentially including its features, functionality, and place within the creator's overall firearm collection.

The 9mm caliber's long-standing dominance is being challenged by newer or resurgent options like .30 Super Carry, 5.7x28mm, 10mm Auto, .357 SIG, and .22 TCM. These alternatives offer advantages in capacity, ballistic performance, recoil management, or terminal energy, catering to specific needs beyond the traditional 9mm balance.

The Freedom Ordnance FG-15 offers a unique trigger crank mechanism integrated into an AR-15 grip, allowing for rapid firing by rotating a deployable crank. This piston-driven system engages the trigger bar mechanically, providing a novel approach to firearm modification. While innovative, its potential NFA implications and mechanical complexity suggest it's for experienced users.

This review showcases the PKM 7.62x54R machine gun, highlighting its full-auto capability and belt-fed mechanism. The video demonstrates the loading process and sustained fire, offering close-up views of the weapon's internals and ammunition.

This video clarifies the terminology between 'silencer' and 'suppressor,' noting 'silencer' is the original patented term. It demonstrates that suppressors reduce sound to around 130 dB, not silence, and discusses their role as hearing protection tools rather than crime enhancers. The process of legally acquiring a suppressor under the NFA, including the $200 tax stamp and lengthy wait times, is detailed, advocating for the Hearing Protection Act.

Using a suppressor on a home defense firearm is generally inadvisable due to the severe noise levels that can cause hearing damage and disorientation. This can lead to dangerous miscommunication with household members, potentially mistaking the defender for an intruder. While suppressors offer benefits, their use indoors without proper precautions poses significant risks to oneself and others.
