Is 556 Relevant for Extended Range? with Bruiser Industries

Sully from Line 45 outlines seven essential calibers for gun owners to stockpile in anticipation of future ammunition shortages, emphasizing their specific roles and the current market conditions. The video highlights the importance of proactive stocking for calibers like 300 Blackout, 308 Winchester, 10mm Auto, 12 Gauge, 22 LR, 223 Remington/5.56 NATO, and 9mm Luger, detailing their performance characteristics and availability challenges.

This guide details how to test propellant temperature sensitivity, a crucial factor for consistent long-range accuracy. It emphasizes using a reliable chronograph and testing ammunition across a wide temperature range, from cold to hot conditions. The process involves calculating the muzzle velocity change per degree Fahrenheit to understand how temperature fluctuations affect performance, enabling shooters to account for these variations in their ballistic solutions.

This video from Line 45 provides a comprehensive overview of 10 calibers experiencing significant price drops in 2025, making them ideal for stocking up. Instructor Ted highlights specific price points, availability, and recommended retailers for calibers like 9mm Luger, 5.56 NATO, .22 LR, and more. The advice focuses on leveraging current market conditions for cost-effective training and practice.

This guide details the process of zeroing a handgun optic, emphasizing the reduction of shooter error by using a stable rest. It covers firing initial groups, calculating adjustments based on optic specifications, and making incremental changes to achieve a precise point of impact at a recommended 25-yard distance, while acknowledging the impact of environmental factors like wind.

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This video from GBRS Group explains the ballistic principles of deviation and deflection. Deviation is defined as a projectile passing through an object, while deflection is a contact that disrupts or changes trajectory. The demonstration uses 5.56x45mm rounds impacting pillars to illustrate these concepts, showing how fragments can cause minor disruption without lethal effect.

This video details a practical plate carrier and belt setup for civilian self-defense and tactical use in 2022. Key recommendations include prioritizing gear tested for your specific needs over influencer trends, choosing a rigid belt like the Led Devil for magazine weight, and selecting modular plate carriers such as the Spiritus Systems LV119. The setup emphasizes independent civilian use, with considerations for comms, medical, and on-range repair tools.

This guide details the advanced setup of a Special Purpose Rifle (SPR) configuration, as presented by Alex Hartman of Ridgeline Defense. Key elements include selecting accurized barrels, free-floated rails, and appropriate optics (3-12x to 3-18x FFP recommended). Emphasis is placed on proper bipod and sling mounting for stability, advanced shooting techniques like the PPEW method, and the critical role of parallax adjustment and laser rangefinders for precision at distance. Instruction is provided by a Subject Matter Expert in precision rifle applications.

This guide details the installation of the Unity Tactical FAST Riser and FAST Micro Mount, emphasizing the benefits of a 2.26-inch height-over-bore for a heads-up shooting posture. It covers mounting procedures, compatibility with optics like EOTech and Aimpoint, and considerations for mechanical offset. The review highlights the durability of 7075-T6 aluminum construction and practical feedback from experienced users.

This video showcases the 'Death Box Drill,' a training exercise designed to test shooting accuracy while under cardiovascular stress. The drill involves moving through a 10x10 yard area and firing two rounds at each corner. Instruction emphasizes analytical shooting, where deliberate practice with feedback is more valuable than high round counts without purpose. The video highlights the importance of mastering fundamentals under stress, drawing on expertise from Milspec Mojo and Matt Tran, with support from sponsors like Big Tex Outdoors.
