Mk262 Cloning - pt 5 - Varget

This YouTube video, part 2 of a "Mk 262 Cloning" series, focuses on replicating the Mk 262 Mod 1, specifically the Black Hills 5.56 77gr OTM ammunition. The experiment tests Accurate 2520 as the powder of choice for this reloading endeavor.

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 is part 7 of a series focused on cloning Black Hills 77gr OTM factory ammunition, commonly known as Mk 262 Mod 1. The experiment specifically tests two powders for achieving this replica load: IMR 8208 XBR and Alliant AR-Comp. The description notes that all external links have been removed to comply with YouTube's content policies, but a Patreon link is provided for support. The video delves into the reloading process and powder performance for this specific ammunition goal.

This video details the process of duplicating Mk 262 Mod 1 ammunition, starting with factory Black Hills 77gr OTM as a baseline. It covers the history of the round, safety considerations for high-pressure 5.56 NATO loads, and a cost analysis showing significant savings through reloading. Baseline accuracy testing with the factory ammo yielded impressive results, averaging 0.595 MOA.

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 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 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.
