This video highlights critical firearm safety failures and explains the concept of 'height over bore.' It demonstrates how the difference in height between a firearm's optic and its barrel affects bullet impact, especially at close ranges. The content emphasizes the importance of understanding this principle and adhering to the four fundamental rules of gun safety to prevent accidents.

This guide details how to test propellant temperature sensitivity, a crucial factor for consistent long-range accuracy. It emphasizes using a reliable chronograph and testing ammunition across a wide temperature range, from cold to hot conditions. The process involves calculating the muzzle velocity change per degree Fahrenheit to understand how temperature fluctuations affect performance, enabling shooters to account for these variations in their ballistic solutions.

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This video from GBRS Group explains the ballistic principles of deviation and deflection. Deviation is defined as a projectile passing through an object, while deflection is a contact that disrupts or changes trajectory. The demonstration uses 5.56x45mm rounds impacting pillars to illustrate these concepts, showing how fragments can cause minor disruption without lethal effect.

This video critiques AI-generated content regarding firearms, highlighting inaccuracies in explanations of vertical grips, pistol optics, and short-barreled shotguns. The presenter, with apparent expertise in firearms, corrects the AI's misconceptions about weapon handling, ballistics, and legal regulations. Key takeaways include the reasons for reduced vertical grip use on modern AR platforms due to evolving grip techniques, the actual reasons police departments may not issue red dots, and the physics behind bullet trajectory and shotgun performance.

This video explores the top 5 deadliest revolver calibers, detailing their ballistic performance, practical applications, and recoil characteristics. It highlights the .357 Magnum for its versatility, the .44 Magnum for its balance of power and manageability, the .480 Ruger for wilderness defense, the .454 Casull for extreme stopping power, and the .500 S&W Magnum as a 'cannon' for the most demanding situations. Proper firearm handling and safety are implicitly emphasized throughout.

This review of the Akdas SA-9 highlights its performance in both full-auto and semi-automatic modes. The speaker demonstrates controlled bursts and timed drills on steel targets, assessing recoil and accuracy. The firearm features a 9mm caliber, 20-round capacity, and iron sights with optic rail compatibility, making it a versatile option for self-defense scenarios.

This video details a long-range marksmanship challenge hosted by Colonel Harold Cabunoc for CAFGU personnel. The drill involves engaging steel targets at 200 and 300 meters, emphasizing practical application of shooting fundamentals like trigger control and sight adjustment. Colonel Cabunoc, a senior military officer, demonstrates high proficiency and provides instructional feedback, highlighting common errors such as improper trigger pull.

This video details a shooting challenge featuring the Glock 21 in .45 ACP, emphasizing marksmanship at varying distances. Expert instruction from Harold Cabunoc, a seasoned shooter, highlights common errors like trigger jerking due to recoil anticipation and provides techniques to improve accuracy. The challenge demonstrates practical application of shooting skills with potential for cash prizes.

This guide details the ballistic testing of a Chinese-made NIJ Level III-A Kevlar helmet, as demonstrated by Harold Cabunoc. It covers testing against 40mm grenade shrapnel, 9mm, .45 ACP, and 5.56mm M855 rounds, providing practical insights into its protective capabilities and limitations against different threats. The assessment highlights the helmet's effectiveness against handgun rounds and shrapnel, while confirming its vulnerability to rifle fire.
