What the Heck is a Cannelure? (Defiant Munitions) #ammo #reloader #gun

This video explains the function of 'cannelure' on self-defense ammunition. Cannelure is a crimp line that prevents bullet setback, a dangerous condition where the bullet is pushed deeper into the casing due to recoil or chambering. Bullet setback can lead to extreme pressure spikes and catastrophic firearm failures. While adding cannelure increases manufacturing cost and time, it is a crucial safety feature for high-quality self-defense rounds.

This entry analyzes an uncommanded discharge incident involving a CZ Shadow 2 pistol during a USPSA match. Expert analysis from Ben Stoeger covers potential causes related to CZ modifications, ammunition sensitivity (Federal primers), and the pistol's operational state (double-action, hammer down). The guide outlines steps to investigate such an event, emphasizing safety and thorough examination of all contributing factors.

This video explores the internal workings of bullet traps, specifically focusing on where "frag" (fragmentation) ends up after a projectile impacts the trap. The description includes a link to purchase a portable bullet trap, suggesting a product-focused or informational video about ballistic containment and safety.

Boondock Ballistician critically analyzes claims of 'record-breaking' 5.56mm ammunition, particularly from Shell Tech and Badlands Munitions. The expert instructor debunks inflated velocity and pressure figures, emphasizing the dangers of misinformation for reloaders and highlighting that standard brass-cased ammunition can achieve similar velocities within safe pressure limits.

This video demonstrates a controlled experiment where different calibers of ammunition (22 LR, 9mm, and .223) are heated on a stovetop to observe their cook-off behavior. The footage, presented by Civilian Tactical, shows the distinct reactions of each round, from projectile and casing separation to the violent expulsion of the pan. The experiment highlights the dangers of heating ammunition and promotes awareness of firearms technology, referencing SDI.TODAY for educational opportunities.

This video introduces the 30 Epic cartridge, a new high-power round designed for the AR-15 platform. Developed by Olympus Arms, Inc., the cartridge aims to maximize power while fitting within standard AR-15 magwells in a double-stack configuration. The focus is on achieving potent performance without compromising compatibility.

This video presents a humorous skit emphasizing the critical importance of wearing eye protection at the shooting range. It visually demonstrates a handgun malfunction and uses a relatable, albeit exaggerated, scenario with a spent casing to highlight the potential dangers of inadequate eye safety. The creator, experienced in firearm handling and tactical gear, reinforces this essential safety message.

This video features a 'bulletproof' test where a tree is used as a ballistic medium to test various calibers from .22 LR up to .50 BMG. The Civilian Tactical host, demonstrating high-level firearms expertise, shows that even powerful rounds like .50 BMG can be significantly stopped by a dense tree, with none of the tested rounds achieving a complete pass-through. The test highlights the surprising terminal ballistics of different ammunition types against natural barriers.

This video from Civilian Tactical explores the concept of using a human body, simulated with ballistic gel, as a suppressor. The host fires a Derya Arms .22 rifle directly against a ballistic gel head and block, noting the shot sounded 'dead silent.' The experiment demonstrates the penetration depth of a .22 LR round through the simulated head and into the gel block.

This video demonstrates a ballistic test on a Belgian M1 steel helmet, evaluating its resistance against various calibers from birdshot to .223. The test, conducted by Civilian Tactical Host, shows that the helmet is not bulletproof against common handgun and rifle rounds like 9mm and .223. The host's energetic and demonstration-oriented style, coupled with expertise in tactical gear, provides a clear assessment of the helmet's limitations.
