NAS3 Is NOT The Next Generation

The US military is transitioning to the 6.8x51mm (.277 Fury) cartridge, replacing the 5.56x45mm NATO round due to its superior lethality and range. This initiative, part of the Next Generation Squad Weapon (NGSW) program, introduces the Sig Sauer XM7 rifle and XM250 light machine gun, featuring advanced technologies like hybrid ammunition and integrated fire control systems. The new caliber aims to enhance soldier effectiveness against modern threats at extended distances.

This segment from Gun Talk Radio discusses SIG Sauer's new hybrid ammunition, a significant advancement in firearm technology. Jason St. John of SIG Sauer explains how this two-piece cartridge, featuring a brass body and stainless steel head, allows for dramatically increased pressures (up to 120,000 PSI) compared to traditional brass cartridges (around 65,000 PSI). This innovation enables higher velocities from shorter barrels, offering tactical advantages for military applications and performance benefits for hunters and civilian shooters. The discussion also touches on the new SIG Experience facility in Exeter, New Hampshire, which includes a pro shop, museum, and indoor ranges.

This video from Line 45, featuring Ted, explores why gun owners are moving away from traditional hollow points in 2025. It details advanced ammunition technologies like solid copper hollow points, fluted solids, tumble-on-impact rounds, bonded JHPs, ballistic tips, frangible ammo, and hybrid loads, highlighting their superior performance in barrier penetration, weight retention, and wound cavity creation compared to older designs. The content is geared towards intermediate to advanced shooters seeking to optimize their self-defense ammunition choices.

This video demonstrates the terminal ballistics of a unique hybrid 12-gauge shotgun shell containing birdshot, buckshot, and a slug. The test, conducted by an instructor with high authority, uses a GForce Arms Filthy Pheasant shotgun and Clear Ballistics gel to analyze the complex wound channel created by the multi-component round.

This video provides an expert overview of the new Sig Sauer XM250 machine gun and XM7 rifle, set to replace the M249 SAW for US Army close combat forces. The presentation, led by a Sig Sauer representative, details the XM250's specifications, including its 13.1 lb weight, open-bolt, belt-fed operation, and new 6.8mm caliber. The advanced 6.8mm hybrid ammunition, featuring a steel base, is highlighted for its ability to handle increased pressure and enhance performance from shorter barrels. Sig Sauer secured the contract for both the XM7 and XM250, marking a significant advancement in US military small arms.

This video investigates galvanic corrosion in Shell Shock NAS3 casings after a 1000-round test and subsequent exposure. The instructor, with a background in chemistry, explains the principles of galvanic corrosion and tests casings left on a range for 90 days and submerged in a salt bath. The findings indicate that the nickel plating on the aluminum base effectively insulates it from the ferromagnetic nickel body, preventing significant galvanic corrosion under normal use conditions.

This guide provides a step-by-step overview of field stripping the SKS rifle, a process essential for cleaning and maintenance. It covers the removal of major components like the dust cover, bolt carrier group, recoil spring, and gas tube. The information is presented with the authority of an experienced firearms instructor, emphasizing safe handling throughout the procedure.

This video provides an expert analysis of current ammunition supply chain issues, explaining how tariffs, geopolitical events, and material sourcing bottlenecks are driving up costs. The speaker, Boondock Ballistician, details the impact of Section 232 tariffs on steel and copper, propellant production shifts, and the nitrocellulose supply chain. It also highlights how increased demand can spur new primer manufacturers to enter the market.

The Boondock Ballistician reviews the PSA H&R 635, a 9mm PCC inspired by the Colt 635. While praising its comfortable ergonomics, minimal recoil, and clean aesthetics (lacking a forward assist), the reviewer encountered significant reliability issues, primarily attributed to straight-profile Uzi-style magazines. These issues included failure to feed and extract, and difficulty seating full magazines. The video also touches on the historical context of the design, its direct blowback operation, and the utility of the A1 carry handle for optics mounting.

This video provides an in-depth review of the Lee Enfield rifle, highlighting its historical significance and operational advantages. The presenter argues it may be the best bolt-action rifle for its use-case perspective, praising its smooth bolt operation, short bolt throw, and 60-degree bolt lift. It details the rifle's adoption by the British Army, its .303 British caliber, and the use of charger clips and detachable magazines, noting James Paris Lee's invention of the latter. The video also touches on its accuracy potential, including its use for volley fire and anti-aircraft roles, and discusses various historical markings and model variations.
