Videos tagged with Venturi Effect

This video provides an expert-level explanation of the PWS Rifle's Bore Evacuation Chamber, drawing parallels to M1 Abrams tank technology. Instructor Ryan details how the Venturi effect creates a vacuum upon projectile exit to evacuate gases, enhancing system performance. The explanation is technical and informative, highlighting advanced firearm engineering.

This video explores the physics and performance of fluted projectiles, often referred to as External Hollow Points (EHPs), comparing them to traditional hollow points. The presenter details the Venturi effect and hydraulic jump principles theorized to explain their performance without relying on expansion. Personal ballistic gel testing, following FBI barrier test protocols, is presented to demonstrate their consistency through barriers and potential for increased tissue damage.

This segment from Gun Talk Radio features Daniel Cox, VP of Product Portfolio at Norma/RUAG, discussing Norma's expanded presence and new ammunition lines in the US market. Cox highlights Norma's commitment to quality control across all manufacturing stages, from brass and powder to primers and bullets. He introduces two new self-defense handgun rounds: the MHP (Monolithic Hollow Point), which is cold-formed to pre-imprint expansion properties, and the NXD (Non-Expanding Defensive), which utilizes fluid dynamics for energy transfer without expansion, offering consistent performance and reduced recoil.

This video details the construction of the 'ArmaLewis,' a custom AR-15 featuring a unique Venturi effect air-cooled barrel system inspired by the Lewis gun. The build incorporates a 16-inch barrel, a side-charging upper from New Frontier Armory, Boyd's wood furniture, and a KCI double drum magazine. The cooling mechanism relies on a linear compensator to draw ambient air through a ventilated barrel nut and across the barrel within a shroud.

This video provides an expert-level breakdown of rifle barrel longevity from a seasoned firearms instructor. It details the primary causes of barrel degradation—heat, erosion, and friction—and how factors like cartridge choice, velocity, and firing habits significantly impact barrel life. Practical advice is offered for hunters and shooters to maximize firearm performance and lifespan.
