Bullet Stabilization and Barrel Twist

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 discusses the emerging dominance of the 7mm PRC caliber in long-range precision shooting, positing it will surpass the 6.5 Creedmoor by late 2026. The 7mm PRC offers heavier bullets (160-195 grains), higher velocities (upwards of 3,100 fps), and greater energy (3,000 ft-lbs), making it a superior choice for distances beyond 800 yards and for hunting larger game. The caliber's rapid growth indicates strong industry backing.

This video provides an in-depth look at the .45 ACP cartridge, dispelling myths and highlighting its modern performance. It details the cartridge's historical context, its effective 'fight stopper' reputation, and its manageable recoil profile, especially in steel-framed firearms like the 1911. The content also touches upon enhanced .45 ACP variants and its suitability for various platforms, including submachine guns and pistol caliber carbines.

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 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 guide details the advanced technique for executing a long-range elk hunt, as demonstrated by a 12-year-old hunter under expert supervision. It emphasizes precise range estimation, scope adjustment using ballistic turrets, and marksmanship fundamentals for a successful shot at extreme distances (1376 yards). The process highlights the importance of preparation, practice, and specialized equipment for challenging hunting scenarios.

This expert guide from Gunwerks demonstrates the significant impact of the Coriolis effect on long-range bullet trajectory. Jeremy Winters, a Gunwerks Product Specialist, explains how Earth's rotation can shift Point of Impact (POI) by over 1 MOA at 1000 yards when shooting East or West. The video provides a live-fire demonstration and recommends shooting North or South to collect accurate ballistic data, minimizing Coriolis-induced errors.

This guide details the process of transforming a factory Remington Model 700 Sendero into a more capable long-range rifle, as demonstrated by Mike Davidson from Gunwerks. Key steps include a trigger upgrade to a 2-pound pull and a precision bedding job using Devcon Aluminum Putty to ensure action stability. The process emphasizes proper disassembly, careful application of bedding materials, and correct reassembly with specific torque values for action screws.

This video demonstrates a professional long-range coyote hunt in Montana, showcasing the effective use of a Gunwerks rifle. Dustin Butler, a representative for Gunwerks, highlights the 'range, dial, and kill' method for successful predator engagement at various distances, from close encounters to over 500 yards. The guide emphasizes proficiency with long-range optics and equipment for accurate shots in challenging terrain.
