This comprehensive review from PewView covers the top 5 shotguns for home defense, ranging from budget-friendly options to high-end tactical platforms. The video highlights the Maverick 88 as a top value pick, discusses classic choices like the Remington 870 and Mossberg 500, and delves into specialized options like the Kel-Tec KS7 bullpup and the AR-style Genesis Arms Gen 12. PewView, an advanced firearms instructor, emphasizes reliability, handling, and performance, offering insights based on extensive practical experience.

This review covers the new Beretta A300 Ultima Patrol in 20 gauge, launched for Beretta's 500th anniversary. The design is an optimization of the popular 12 gauge model, featuring an M-LOK compatible forend, enlarged loading ports, and a dedicated optics mount. The shotgun offers a 7+1 capacity with 2.75-inch shells and can handle 3-inch loads, making it a versatile option for tactical applications.

This review of the Benelli M4 EXT highlights its factory-equipped upgrades, addressing common owner modifications for increased capability and speed. The shotgun features a 7+1 capacity, a 5-position collapsible stock with a pistol grip, and oversized controls. It is chambered for 2.75" and 3" shells and utilizes the ARGO gas system, though it may be sensitive to very light loads. The review is presented by SGM (RET) Karl Erickson, offering expert insights into its performance and tactical applications.

This video explores the evolution of the double-barrel shotgun, contrasting classic over-under designs with modern tactical variants like the Standard Manufacturing SSR (DP-12). The presenter demonstrates the SSR's unique simultaneous firing capability and tests its performance with slugs, highlighting the intense recoil and questioning its tactical applicability. The review is delivered with high energy and clear technical explanations from an authoritative source.

The Mossberg 990 Aftershock is reviewed as a potential Short Barreled Shotgun (SBS) host, noted for its gas-operated action and compatibility with Magpul SGA stocks. However, the firearm exhibits significant reliability issues, particularly with lighter ammunition, due to a theorized weak extractor. Mechanical flaws like the M-LOK ratchet system backing out also detract from its performance.

This video explores the theoretical and practical outcome of loading a 50 BMG cartridge into a 12 gauge flare gun. The experiment, conducted by a hobbyist, demonstrates that while the 50 BMG cartridge surprisingly fits, the flare gun's firing mechanism and primer strength are insufficient to ignite it. The test highlights the significant differences in primer resistance between ammunition types.

This video debunks the myth that shooting upwards is safe, explaining the lethal terminal velocity of falling projectiles. It showcases the Canik Mete MC9 Prime with a Gideon Valor optic and demonstrates the use of 9mm shot shells for controlled, less dangerous demonstrations, highlighting their unique projectile dispersal.

This video debunks the myth that a .50 BMG round passing near a target can be lethal due to shockwave. Using a ballistic mannequin head and a Big Kahuna Firearms Raptor-50 rifle, the test demonstrated that while the .50 BMG round impacted and destroyed a concrete block behind the target, it did not affect the mannequin or the cardboard placed near it. The conclusion is that a near miss from a .50 BMG is not fatal.

This video conducts a destructive test comparing the impact of .22 LR and .50 BMG rounds on a ballistic head model. The .22 LR caused minimal damage, while the .50 BMG completely destroyed the head, highlighting the vast difference in energy and destructive potential between the two calibers. The test also showcases the Raptor .50 BMG upper receiver as an accessible way to experience .50 BMG ballistics on an AR-15 platform.
