Quick Tip: What Is Ballistic Coefficient?

This video provides an expert-level explanation of Ballistic Coefficient (BC) from a seasoned firearms instructor. It details how BC affects bullet trajectory and wind drift, emphasizing its importance for long-range accuracy (500-1000 yards). The instructor also covers factors influencing BC like bullet mass and shape, and discusses the critical interplay between BC, bullet weight, and rifle twist rate, cautioning against manufacturers overstating BC values.

This video explains Ballistic Coefficient (BC) as a measure of how well a bullet penetrates air, influenced by its shape. A higher BC means less drag, resulting in reduced bullet drop and wind drift. The instructor highlights that sharply pointed noses and boat tail bases contribute to a higher BC, making them ideal for precision shooting.

This guide details how to develop a rifle's Data On Previous Engagements (DOPE) for accurate long-range shooting. It emphasizes the importance of a precise zero and accurate input data into ballistic calculators, including muzzle velocity, bullet specifications, and rifle measurements like height over bore. The process involves generating a range card, recording data, and truing up the ballistic solution through live fire adjustments to ensure consistent hits at various distances.

This video delves into the critical factors influencing rifle accuracy, particularly for precision shooting and hunting beyond 500 yards. It emphasizes that while bullet Ballistic Coefficient (BC) is important, factors like velocity standard deviation (SD) and projectile shape significantly impact dispersion. The analysis highlights that at longer ranges, the aerodynamic efficiency of a bullet becomes more critical, especially in windy conditions, and that trade-offs exist between maximizing BC and minimizing dispersion.

This episode of Wind Call Wednesday, presented by Ghost Firearms Training LLC, introduces a challenge where viewers judge wind conditions solely by observing mirage. The instructor, demonstrating expert authority, emphasizes using mirage over wind flags for accurate wind calls. The video details the specific equipment used, including a Ruger Precision Rifle in 6.5 Creedmoor and American Gunner ammunition, along with environmental data, to illustrate the factors influencing long-range accuracy.

This video demonstrates that a budget AR-15 build, often referred to as a 'Special (Poor's) Rifle' (SPR), can achieve practical accuracy at 1000 yards for under $1000. The hosts, experienced shooters, highlight the evolution of the AR market and the accessibility of long-range shooting with modern optics and ammunition, while also discussing potential challenges with budget components.

This guide details the installation of a Geissele MK8 Super Modular Rail on an AR-15 platform. It covers securing the upper receiver, installing the barrel nut, gas system, and the rail itself, emphasizing the use of specialized tools and proper torque specifications. The process requires an intermediate skill level and careful attention to detail for a secure and functional build.

This guide, based on expert instruction from Brownells, details essential practices for proper ammunition storage. It emphasizes using airtight containers, managing humidity with desiccants, and maintaining stable temperatures to ensure ammunition reliability and safety. Proper storage is crucial for preventing corrosion and propellant degradation, especially for sensitive components like primers.

This guide details the process of upgrading an AR-15 from standard A2 furniture to Magpul components. It covers the removal of the A2 pistol grip and installation of the Magpul MIAD Grip and Magpul PRS Stock. The video demonstrates efficient assembly using specialized tools, highlighting the ergonomic benefits and adjustability of the Magpul parts. Instruction is provided by Brownells, a recognized industry authority.

This entry details the creation of a movie prop suppressor for a Remington 11-87 used in 'No Country for Old Men.' Prop master Larry Zanoff explains how the suppressor was designed to look homemade and was non-functional, with sound effects added in post-production. The process highlights the creative problem-solving involved in film armory.
