This video tests the ballistic resistance of a Soviet-era hammer against various calibers. While smaller rounds like .22 LR caused minimal damage, larger calibers like 9mm, 7.62x39mm, .223 Remington, and .308 Winchester inflicted progressively more damage, with the .308 ultimately causing significant structural failure to the hammer's handle.

This video tests the ballistic resistance of an actual helicopter blade against a wide array of calibers, from .50 BMG down to .22 LR. The host, Scott from Kentucky Ballistics, systematically fires various firearms at the blade, documenting penetration and stopping power. The results reveal that while larger calibers like .50 BMG and .416 Rigby easily penetrate the blade, smaller pistol calibers and even some rifle rounds can be stopped by certain sections, particularly the thicker base. The experiment concludes by revealing the blade is surprisingly hollow in its core structure.

This video tests the ballistic resistance of forklift forks against various calibers, culminating in a .50 BMG round. The experiment demonstrates that even thinner sections of forklift forks can withstand lower caliber rounds, while thicker sections and even the thinner parts prove highly resistant to higher calibers. The .50 BMG successfully penetrates the thinner sections but is stopped by approximately 1 inch of material, highlighting the forks' exceptional durability.

This video provides an expert overview of the Third Bay Ounce Folding Pistol, addressing its potential for 3D printing and detailing its complex material composition. Bill Osborne from Third Bay, LLC explains the firearm is constructed from 18 CNC steel parts, 2 brass parts, 10 aluminum parts (including the case), and 10 injection-molded plastic parts, with the handle being the largest plastic component. High-end engineering thermoplastics with significant glass fiber fill and graphene are used for enhanced properties, indicating a sophisticated manufacturing process rather than simple 3D printing.

This video from FalconClaw, featuring expert instructor Callsign_Gundoctor, explains the principles of thermal signature management in tactical gear. It demonstrates how materials like ripstop tarps, while offering camouflage, do not inherently block thermal detection once in contact with a heat source like the human body. The content highlights the limitations of passive thermal blocking in clothing and gear.

This video from AT3 Tactical explains why Inconel, a chromium-nickel alloy, is not typically used for rifle barrels. Despite its excellent heat erosion resistance, making it common in suppressors, its extreme weight, difficulty in machining, and high cost render it impractical for standard barrel lengths. The expert speaker highlights these manufacturing constraints.

This entry details the development and engineering of SureFire suppressors, drawing on the expertise of Barry Dueck, a key figure in their design. It covers historical context, material science advancements like Inconel, military contract requirements, and specific features of models like the SOCOM556-RC4 and Mini 4, including innovative flash reduction techniques and modern manufacturing processes. The information is presented with an authoritative tone, reflecting Dueck's deep knowledge and experience.

This video explains the durability and workability of G10 grips, contrasting them with other materials. G10 is presented as a superior option due to its stability, resistance to cracking and chipping, and ease of modification. The speaker highlights its use in both firearms and high-end power tools.

This YouTube video explores whether a standard bag can offer ballistic protection. While specific firearms or calibers are not mentioned in the provided title and description, the core premise revolves around the concept of bullet resistance and its application to everyday items. This suggests a potential examination of materials, impact testing, or the limitations of non-armored gear against projectile threats. The content likely aims to educate viewers on the realities of ballistic protection versus common misconceptions, potentially touching upon the effectiveness of tactical gear or personal defense scenarios.

This video provides an in-depth look at Olight's new OAL (Super Aluminum) material, showcasing its remarkable durability through rigorous scratch and drill tests against traditional aluminum, titanium, and steel. The presenter, an experienced reviewer with over 13 years in the EDC community, demonstrates OAL's superior resistance to damage and its minimal weight penalty. The review also covers various Olight 'Ultra' series products, highlighting their features and performance.

This video tests the ballistic resistance of NeeDoh stress balls against various firearm calibers, from .22LR up to .50 BMG. The presenter, from Demolition Ranch, demonstrates how the squishy material behaves like a non-Newtonian fluid, hardening under impact but ultimately failing to stop larger calibers. High-speed footage reveals projectile disintegration and energy transfer.
