Bullet Penetration & Shoulder Stabilization

This video, titled "Kill the Enemy with Science: Rifleman’s Guide," appears to be an instructional or informational piece aimed at rifle enthusiasts. While the description is minimal, focusing on channel support links, the title suggests a content focus on applying scientific principles to rifle marksmanship and potentially combat effectiveness. The video likely delves into the technical aspects of shooting, ballistics, or tactical considerations for riflemen.

This video, titled "A Layout Of All The Capabilities Of A 5.56mm From Close Range To Long Range," features Rughi detailing the performance characteristics of the 5.56mm cartridge across various distances. The content emphasizes a "by the numbers" approach, drawing from the presenter's personal experiences to illustrate the caliber's versatility. The description encourages viewer engagement through likes, subscriptions, and comments, while also promoting a "Shooters Club" for exclusive perks and providing links to training schedules, classes, and affiliate discounts.

Zeroing a firearm under 10 yards is often counterproductive for self-defense scenarios. Demonstrations show that closing the distance to 10 yards can happen faster than a sighted draw. A 15 to 25-yard zero for 9mm handguns is recommended for a flatter trajectory out to 50 yards.

This video explains the benefits of a 36-yard zero for the AR-15, highlighting its ability to keep impacts tightly stacked from 25 to 250 yards, making it ideal for competition and unknown distance shooting. It details the process of achieving this zero, including bore sighting, initial group firing, MOA calculations at 36 yards, and refining the zero. The discussion also touches on how ammunition and barrel length can affect zero, recommending the Applied Ballistics app for precise calculations.

This YouTube Short explains the concept of 'Height Over Bore' in firearms. Height Over Bore refers to the distance between the center of the firearm's bore (barrel) and the top surface of the hand that is gripping the firearm. This measurement is crucial for understanding how much a firearm will move upwards during recoil, which impacts follow-up shot speed and accuracy. Understanding this principle helps shooters make informed decisions about firearm selection and shooting techniques.

This expert-level guide from Farewell Firearms Training emphasizes the critical concept of rifle optic offset and its impact on shot placement. Instructor demonstrates how to accurately call shots by focusing on where the aiming point lifts during recoil, rather than the trigger pull itself. This technique is crucial for understanding ballistics, especially at close distances where the 3-inch offset significantly affects the point of impact.

This video showcases a remarkable 1376-yard elk hunt by a 12-year-old using a Gunwerks rifle chambered in 7mm Rem Mag. It highlights the critical importance of precise range estimation, scope adjustments (32.5 MOA), and marksmanship for extreme long-range success. The hunt involved significant preparation, including hiking and dry-fire practice, culminating in a successful two-shot engagement on a bull elk.

This video demonstrates the significant impact of the Coriolis effect on long-range bullet drop, particularly at 1000 yards. Experiments show directional POI shifts of up to 11 inches (over 1 MOA) when shooting East vs. West due to Earth's rotation. The data suggests collecting ballistic data North or South to mitigate this vertical error.

This video details the initial steps in transforming a factory Remington 700 Sendero into a long-range precision rifle. Key modifications include upgrading the trigger to a crisp 2-pound pull and performing a crucial bedding job on the recoil lug for enhanced shot-to-shot consistency. The process emphasizes meticulous preparation and precise application of bedding compounds and torque settings for optimal performance.

This video showcases a successful long-range coyote hunt in Montana using a Gunwerks rifle. Dustin Butler demonstrates effective predator calling and engagement techniques, highlighting the rifle's performance across various distances, from close-range shots to over 500 yards. The 'range, dial, and kill' workflow is emphasized for efficient long-range hunting.
