223 Remington - 70gr Barnes TSX & Hornady GMX

This video from Civilian Tactical explores five distinct types of .223 Remington and 5.56 NATO ammunition. The host, demonstrating experienced firearm instruction, details the unique characteristics and intended applications of each round, including Hornady VMAX for varmint hunting, M855 'green tip' penetrators, visible tracer rounds, cost-effective steel-cased options, and Double Tap hollow points for defense. The presentation emphasizes understanding terminal ballistics and proper ammunition selection for various scenarios.

This video tests the penetration capabilities of various calibers, from 9mm to .50 BMG, against metal water barrels filled with water. Results show that while smaller calibers are stopped by the first barrel, larger rounds like the .50 AE and .308 penetrate further. The .50 BMG successfully penetrates the first barrel and is stopped by the second, demonstrating significant stopping power.

This video tests the penetration capabilities of various firearms rounds in a swimming pool, from .22 LR to .50 BMG. Surprisingly, higher velocity rifle rounds like the .223 and .308 fragmented quickly, while the .50 AE Desert Eagle traveled the furthest at 190 inches. The .50 BMG sniper rifle, despite its power, only penetrated 61 inches, likely due to massive energy displacement.

This video tests the penetration power of various calibers against a concrete-filled bucket. Handgun rounds (.22 LR, 9mm, .45 ACP) and a .223 rifle round were stopped by the concrete. However, a .50 BMG sniper rifle round easily penetrated the bucket and a mannequin behind it, highlighting the significant power difference.

This video discusses the 69-grain Sierra MatchKing (SMK) projectile for 5.56mm/.223 Remington ammunition. The creator highlights why this specific bullet weight is a "sweet spot" for many rifle setups, particularly those with 1:7 and 1:8 twist barrels. It's presented as a balanced option for ballistic performance, barrel compatibility, and cost-effectiveness, suitable for general-purpose builds, Designated Marksman Rifle (DMR) setups, and training. The video aims to educate viewers on the practical benefits of this popular ammunition choice, encouraging engagement in the comments. It also promotes the creator's associated platforms for exclusive perks, training schedules, and affiliate discounts.

This YouTube video focuses on the ballistic performance of the 5.56mm cartridge, specifically investigating its velocity drop (FPS) over distance. The title directly asks how fast 5.56 loses velocity, indicating a scientific or data-driven approach to understanding this common rifle caliber. The description provides a link to tatargets.com, suggesting the video might be related to ballistics testing, ammunition performance, or target shooting equipment, potentially offering insights relevant to shooters and firearm enthusiasts interested in the practical application of their firearms.

This video demonstrates a successful method for removing a severely stuck case from an AR-10 barrel using a high-pressure grease gun and hydraulic oil. Despite a previous gunsmith's failure, the technique involving a custom adapter and specialized grease gun achieved extraction. Post-removal inspection and range testing confirmed the barrel's integrity and sub-MOA accuracy.

This video provides a comprehensive guide to reloading ammunition for the Thompson Center Compass chambered in 300 Winchester Magnum. It meticulously covers each stage of the reloading process, from an introduction and detailed discussion of components and equipment to the practical steps of brass resizing and preparation, load data analysis, setting overall length (OAL), priming, powder charging, and bullet seating. The video culminates in a range test to evaluate the reloaded ammunition, followed by a brass inspection and group review, and concludes with future plans. The content is highly educational for anyone looking to start reloading this specific caliber and rifle.

The Vortex Diamondback Tactical 6-24x50 offers excellent value for its $400 price point, featuring First Focal Plane (FFP) capability and a usable EBR-2C reticle. While it shows some chromatic aberration and has slightly mushy turrets compared to higher-end models, its tracking accuracy is comparable to the more expensive Strike Eagle. It's a strong contender for budget-conscious long-range shooters, though FFP might be less ideal for hunting than SFP.

This video explores the experimental firing of .22 airgun pellets using .22 caliber nail gun blanks, achieving velocities over 2200 fps with Level 4 loads. Despite some pellet instability at 50 yards, accuracy remained surprisingly tight, demonstrating the potential for this unconventional projectile method. The host emphasizes proper muzzle-loading technique for rifling engagement and uses a chronograph for precise data collection.
