Cloning Mk262 - Winchester 748 & 760

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 the .223 Remington cartridge, specifically with a 77gr Sierra Match King bullet. It explores the use of two different powders: Alliant Power-Pro Varmint and VihtaVuori N140. This is presented as the 14th episode in a "Mk 262 Mod 1 clone" series, indicating a focus on recreating or testing ammunition configurations relevant to military or competitive shooting. The inclusion of 'Varmint' in the powder name suggests potential applications beyond target shooting.

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 the use of the Lee Precision Micrometer Adjust Screw. The creator is shown loading popular .223 Remington ammunition loads, highlighting the functionality and potential benefits of this reloading component for precision adjustments in ammunition manufacturing.

This video focuses on a range test and comparison of .223 Remington ammunition and reloading dies. The primary ammunition being tested is the 40gr Hornady V-Max, loaded with VihtaVuori N133 powder. The video also highlights a comparison between the Lee Collet Neck Sizing Die and a Mighty Armory full-length die, providing insights into their performance and differences for .223 Remington reloading.

This video provides a detailed examination of reloading components for the .223 Remington cartridge. It specifically tests three different brands of sizing dies: Lee, Redding, and Mighty Armory. Additionally, the video evaluates two expanding mandrels from 21st Century and K&M. The focus is on the performance and characteristics of these reloading tools when used with .223 Remington brass, offering insights for reloaders looking to optimize their process for this popular rifle caliber.

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.
