224 Valkyrie - 69/77/90gr Match Kings with 8208XBR & Varget

This video explores the accuracy potential of the 224 Valkyrie cartridge by testing three different weights of Sierra Match King bullets (69gr, 77gr, and 90gr) using Hodgdon CFE 223 powder. The focus is on achieving precision with this relatively new rifle caliber, continuing the search for optimal loads and bullet combinations.

This video from SHOT Show 2018 showcases new firearms from Savage Arms designed to chamber the .224 Valkyrie ammunition. The description highlights the growing popularity of this new cartridge from Federal Premium and Savage Arms' commitment to supporting its market launch with a range of new rifle models. Viewers can expect to see the latest offerings from Savage Arms that are chambered in this emerging caliber.

This video conducts a comparative test of two 70-grain projectile types for the .223 Remington cartridge: the Barnes TSX and the Hornady GMX. The testing focuses on performance using two specific rifle powders: Vihtavuori N540 and IMR 8208 XBR. The content appears to be geared towards rifle enthusiasts and handloaders looking for data on these specific bullet and powder combinations.

This head-to-head range test compares 1:7 and 1:6.5 twist barrels for the .224 Valkyrie cartridge using heavy projectiles. Contrary to common assumptions, the 1:7 twist barrel demonstrated surprising stability with the 95gr Sierra MatchKing and 90gr SMK, even outperforming the 1:6.5 twist in some instances. The test also highlighted issues with brass longevity and primer pocket looseness at high pressures.

This video focuses on testing and evaluating a specific ammunition load for the .223 Remington cartridge. The content explores the performance of the 65gr Cutting Edge MTH (Match/Tactical/Hunting) bullet. Two popular reloading powders, IMR 8208 XBR and Hodgdon Varget, are used in conjunction with this bullet, indicating a deep dive into handloading precision and application for this common rifle caliber. The video likely aims to inform reloaders and shooters about the capabilities of this particular bullet and powder combination for various shooting disciplines.

This video details a reloading project for .308 Win using 175gr Sierra Match King bullets and IMR 4064 powder, aiming to replicate Federal Gold Medal Match performance. Testing involved a load ladder from 42.0 to 42.8 grains in a JP Supermatch barrel, with both suppressed and unsuppressed firing. Case capacity differences between brass types were highlighted as a critical factor for pressure management, especially with military brass. While accuracy was generally disappointing, the best group achieved was 0.902 inches unsuppressed at 42.4 grains.

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.
