.223 Rem - 77gr Sierra Match King with Varmint and N140

This video demonstrates the reloading process for three distinct firearms: a G-Force Arms Chronicle 1911 pistol using 9mm rounds, a G-Force Arms Gatlander shotgun with 12 Gauge shells, and an AR-15 platform rifle chambered in 5.56/.223. It showcases basic magazine loading and firearm manipulation techniques for each platform, emphasizing practical application in an outdoor range setting.

This video focuses on handloading .223 Remington and 5.56x45mm ammunition, specifically attempting to replicate the MK 262 load using 75gr Hornady BTHP bullets. The initial powder tests involve VihtaVuori N540 and Alliant Power-Pro Varmint. The description also includes links for viewer support and mentions potential affiliate links for products.

This video is the 12th installment in a series focused on "cloning" Mk262 ammunition. The goal is to achieve accuracy and high velocity for the 77gr Sierra Match King bullet when loaded in .223 Remington cartridges. The video discusses using Winchester 748 and 760 powders in this process. The description notes that links were removed in September 2018 to comply with YouTube policies.

This video focuses on handloading ammunition for the .223 Remington cartridge, specifically utilizing 77gr Sierra Match King bullets. It's presented as the 13th installment in a "Mk 262 Mod 1 clone" series, indicating a focus on replicating a known military specification. The primary powder tested is VihtaVuori N540, with comparisons also being made to Accurate 2520, IMR 8208 XBR, and AR-Comp powders. The bullet features a Cannelure, which is relevant for certain reloading techniques. The description notes that all external links have been removed to comply with YouTube's policies.

This video focuses on reloading ammunition for the .223 Remington cartridge, specifically using 77gr Berger OTM Tactical projectiles. It highlights the use of Accurate 2520 powder as a component in this load. The description indicates that links were removed to comply with YouTube's policies.

This video details the process of cloning Mk262 Mod 1 ammunition using BL-C(2) and Ramshot TAC powders with 77gr Sierra MatchKing bullets. While both powders achieved the target velocity of ~2750 fps at an OAL of 2.246 inches, neither provided optimal accuracy at higher pressure levels, with BL-C(2) showing significant degradation and TAC performing slightly better. CCI No. 41 primers yielded higher velocities than Remington 7 1/2 primers when used with TAC.

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.
