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

This video from Defiant Munitions explains the concept of 'cannelure' in firearms ammunition. Cannelures are grooves or indentations found on bullets or cartridge cases, serving various purposes such as aiding in case neck tension for proper bullet seating, preventing bullet setback during recoil in tubular magazines, and acting as a crimping point for some ammunition types. The explanation aims to demystify this often-overlooked feature for firearm enthusiasts.

This video explores the lethality and practicality of 3D printed PLA ammunition in 9mm and .45 ACP. Testing revealed significant issues with accuracy, keyholing, and lack of cycling in semi-automatic firearms. While capable of penetrating soft targets at close range, the ammunition is deemed impractical for self-defense due to its low energy and poor performance.

This video introduces the Hickory Flat Boars 'Havoc BB Shell,' a 12-gauge shotgun shell designed to maximize damage by filling the empty space in traditional buckshot shells with BBs. Tests demonstrate significant damage to water jugs, car doors, and ballistics gelatin, showcasing the combined effect of 00 buckshot and BBs. The content highlights innovative ammunition design for increased terminal ballistics.

This video focuses on the RCBS MatchMaster Powder Funnel Kit, presented by Roy. While the specific title and description don't detail the product's application or the firearms it might be used with, it strongly suggests a review or demonstration of reloading equipment. The content is likely aimed at handloaders and those involved in precision shooting or firearm maintenance.

This YouTube video focuses on the Lee Precision Factory Crimp Die, a reloading tool. The content likely demonstrates its use, discusses its benefits, and provides insights into handloading ammunition. As a specific reloading component, it caters to enthusiasts involved in the meticulous process of crafting their own cartridges.

This experiment tests the lethality of custom-made JB Weld epoxy bullets loaded into 12-gauge shotgun shells. While highly inaccurate, the JB Weld bullets demonstrated significant penetration and were proven lethal in ballistics gelatin tests, passing through a gelatin head. The experiment highlights the potential for DIY ammunition but underscores its practical limitations in accuracy.

This comedic skit humorously emphasizes the critical importance of wearing eye protection at the shooting range. It illustrates a handgun malfunction, specifically a stovepipe, and uses a visual gag with a spent casing to drive home the safety message. The creator showcases tactical gear and a Sig Sauer P365 XL, demonstrating firearm handling in a range environment.

This video tests the penetration capabilities of various calibers, from .22 LR to .50 BMG, against a tree. Surprisingly, even the powerful .50 BMG round failed to penetrate the tree completely, demonstrating the significant stopping power of natural barriers against firearms.

This video explores the hypothetical concept of using a human body as a suppressor, simulating the scenario with ballistic gel. A Derya Arms .22 rifle is fired into a ballistic gel head, with the host noting the shot sounded 'dead silent'. The experiment demonstrates the penetration depth of a .22 LR round through the simulated head.

This test evaluates the ballistic protection of a Belgian M1 steel helmet against various calibers. While it stopped birdshot, .22, and .380 Auto rounds, it failed to defeat 9mm and .223 Remington rounds, indicating it is not suitable for protection against common handgun or rifle threats.
