223 Rem - Shooters World Match Rifle powder

This YouTube video presents a velocity test of Fiocchi Sierra MatchKing 69 grain .223 ammunition. The title explicitly states the caliber, bullet weight, and a measured velocity of 2,850 feet per second. This type of content is highly relevant to firearm enthusiasts interested in ammunition performance, ballistics, and potential applications for their firearms.

This video explores the sound signatures of various black powder firearms, from flintlock muskets to rifled muskets, by experiencing them from the receiving end behind a berm. It contrasts these with a modern suppressed 5.56mm rifle, highlighting differences in projectile sound and impact. The experiment also touches on the effect of patching on gas seal and velocity, and compares the physical projectiles and accuracy of different calibers.

This video provides an introduction to Heckler & Koch's (HK) 433 and G39 rifle platforms. It showcases different variants, including the 433 PDW, and highlights their chamberings in 5.56x45mm and 7.62x39mm respectively. The visual evidence suggests these firearms are equipped with modern optics like EOTech sights, indicating a focus on contemporary firearm technology.

This video provides an expert overview of three distinct Zastava AK platforms. It highlights the Zastava M91 for its long-range capabilities in 7.62x54R, the compact and economical Zastava M85 in 5.56, and the upcoming semi-auto, belt-fed Zastava M84 based on the PKM design. The instructor's authoritative tone and detailed knowledge signal significant expertise in firearms.

Elliott Delp reviews the Global Ordnance 15 Upper, highlighting its monolithic barrel construction for improved reliability and an integrated suppressor mount. Accuracy testing revealed it performs as a General Purpose Rifle, with the best group at 1.68 inches using Hornady V-Max 55gr. The inclusion of an adjustable BCG and suppressor mount at an $800 MSRP offers significant value for a reliable 'fighting rifle' setup.

This video details the process of accessorizing and modifying an HK MR556A4 rifle. It covers installing ergonomic enhancements like rail covers and a hand stop, upgrading the muzzle device for suppressor compatibility with an Angled Spade Technologies Dominion-PB, and setting up an optic system using Midwest Industries risers for a Vortex AMG UH-1 and Micro3X magnifier. The speaker, identified as Tactical Advisor, demonstrates a practical approach to customizing the platform.

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.
