.300 Blackout AR Pistol Subsonic Vs. Supersonic Ammo Clay Test. Takin' a Break From the Ammo Hunt.

This YouTube video investigates the effectiveness and lethality of subsonic 5.56mm ammunition when fired from an AR-15 platform. The creator aims to debunk the common notion that AR-15s are not designed for subsonic loads by testing their performance. The video also includes mentions of their sponsor, Aura, and encourages viewer support through Patreon and PayPal, along with links to their Instagram and camera gear.

This test compares subsonic and supersonic .22LR ammunition lethality using Clear Ballistics gelatin and a cloth barrier. Results indicate that heavy subsonic FMJ rounds can penetrate beyond the FBI's 12-inch minimum, challenging the assumption that they are less deadly than supersonic hollow points. The supersonic hollow point demonstrated expected mushrooming.

This guide, presented by Justin from Palmetto State Armory, explains the critical role of barrel twist rate in stabilizing .300 Blackout projectiles. It details how faster twists (1:5) are ideal for heavier subsonic rounds, while slower twists (1:7) excel with lighter supersonic rounds. The information is derived from practical range testing, demonstrating the performance differences between twist rates and ammunition types.

This review of the Lead Star Grunt AR pistol in .300 Blackout, presented by Nutnfancy, highlights its evolution from a niche item to a 'totally cool' option for personal defense, especially in compact roles. The firearm demonstrates impressive reliability and accuracy, outperforming 9mm PCCs in ballistic energy. It features a 10.5-inch 4150V barrel and forged receivers, with potential for user upgrades like a Rise Armament trigger.

This review compares the Brownells BRN-180 Gen 3 and the PSA Jakl, highlighting significant reliability issues with the BRN-180 Gen 3, which consistently failed to reset its trigger across multiple units. In contrast, the PSA Jakl performed well, demonstrating soft recoil and consistent accuracy after minor adjustments. The BRN-180 Gen 2 is still recommended for its lighter weight and softer shooting characteristics.

This video provides an expert overview of the Palmetto State Armory (PSA) AXR rifle system, introduced at SHOT Show 2024. The AXR features a short-stroke piston system, making it lighter than the JAKL, and offers enhanced modularity with bolt-on rails and AR-15 barrel nut compatibility for easy home barrel swaps. It is designed for suppressor use with an adjustable gas knob and is expected to be released in early summer with pricing comparable to existing JAKL models.

This review covers the Mossberg Maverick 88, a budget-friendly 12-gauge pump-action shotgun, highlighting its simplicity and reliability for home defense. It details a comparison with the Mossberg 500/590, a full field strip, and the use of the Opsol Mini-Clip adapter with Aguila Minishells to increase capacity and ensure reliable cycling. Range tests confirm the adapter's necessity for 100% Minishell reliability.

This test evaluates Federal Syntech Defense 9mm SJHP ammunition using a Canik Mete MC9 and Glock 17. The ammo consistently segmented into three petals and a core, with the core penetrating 18-18.5 inches and segments stopping around 9 inches. Velocity averaged 1033 fps from the MC9 and 1094 fps from the G17, demonstrating high consistency.

The Taurus Model 856 in .38 Special is a capable snub-nose revolver, offering a smooth trigger and good accuracy for its class. It performs well in both single and double-action at typical defensive ranges, with comfortable grips aiding recoil management. The 856 proves to be a reliable and aesthetically pleasing option for concealed carry or self-defense.

This review tests three .380 ACP ammunition types in a Ruger LCP Max with a heavy clothing barrier over ballistic gel. The Winchester 95gr FMJ, Underwood 90gr Xtreme Penetrator, and Federal 99gr Hydra-Shok Deep were evaluated for penetration and expansion. Despite being FMJ, the Winchester proved to be the most effective due to superior penetration, outperforming premium defensive rounds that failed to expand.
