Building a Better Ballistic Coefficient

This video from Brownells Gun Techs explains the concept of Ballistic Coefficient (BC), a crucial factor in understanding bullet performance, especially for long-range shooting. Caleb and Steve detail what BC represents – a bullet's ability to overcome drag and wind resistance – and how it's typically expressed as a decimal less than one. They highlight that a higher BC number indicates a more efficient bullet that flies flatter and is less affected by external forces. The explanation includes practical examples, contrasting the BC of a long, narrow target bullet with a short, squat .45 ACP round. The video emphasizes BC's importance for distance shooting while noting it's less critical for close-range engagements, with Caleb offering insights into why a high BC bullet isn't always the optimal choice.

This video delves into the critical aspects of bullet design and its direct correlation with long-range performance. The title, "Anatomy of a Bullet," and description, "Relatively small differences in bullet shapes can have a large impact on long range performance," suggest an in-depth exploration of ballistics, aerodynamics, and how subtle variations in projectile construction influence accuracy and effectiveness at extended distances. This content is geared towards individuals interested in the technicalities of ammunition and its application in precision shooting or long-range engagements.

This experiment demonstrates the significant energy loss of a 6.5 PRC round at one mile. While it easily penetrates multiple HardieBacker boards and steel at close range, at a mile it fails to penetrate 1/4 inch steel and is stopped by Level 3A body armor, which it would easily defeat at 10 feet. This highlights how extreme distances can drastically alter terminal ballistics.

This YouTube video, Part 3 of the Gseven Ballistic Calculator series, focuses on the outputs generated by the calculator. It covers essential elements like units of measurement, tabular data displays, and drop charts, providing a detailed look at how the calculator presents ballistic information to the user. The content aims to clarify the practical application and interpretation of the calculator's results.

This video, "Gseven Ballistic Calculator - Part 1," introduces the Gseven Ballistic Calculator. It covers the initial login process, explains how to input basic parameters necessary for ballistic calculations, demonstrates the save functionality for user data and settings, and points viewers to the available help files for further assistance. This is the first part of a series likely to delve deeper into the calculator's features.

This video from Brownells debunks the myth that match ammunition is always superior to standard ammunition. Experts Steve and Caleb explain that while match ammo offers enhanced consistency for precision and long-range shooting, it won't fix underlying issues with a firearm's barrel. For typical hunting distances (100 yards), the difference is often negligible.

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.
