Buckeye Ballistics provides an in-depth analysis of Federal HST 124gr +P 9mm ammunition performance across various barrel lengths (3.3" to 10.5"). The expert demonstrates high authority through detailed calibration of ballistic gelatin and analysis of velocity's impact on bullet expansion and penetration. The test highlights how longer barrels increase velocity, leading to more dramatic expansion, but also increased drag, which can affect penetration depth.

This video provides an in-depth evaluation of a 20-inch Red Right Hand LMG HBAR AR-15 barrel manufactured by Rosco. The instructor meticulously inspects the barrel's physical characteristics, including dimensions, weight, and bore condition using a borescope. He then conducts extensive live-fire testing with multiple ammunition types, collecting detailed data on velocity, group size, and shooter stability. The evaluation highlights potential quality control issues, such as chrome failure and bore imperfections, while also assessing the barrel's performance in a simulated LMG role.

This video provides initial impressions and performance data for the new 338 ARC cartridge, comparing it to the 300 Blackout and 8.6 Blackout. The CMMG Dissent rifle chambered in 338 ARC is tested for velocity with both subsonic and supersonic loads, demonstrating its potential for suppressed shooting and hunting applications. The presenter highlights the cartridge's design, which allows for similar overall length to 300 Blackout while utilizing a larger diameter bullet.

This video compares the 270 Winchester and the new 277 Fury (6.8x51mm) cartridges, analyzing their ballistic performance through velocity and muzzle energy measurements. The presenter demonstrates that while ballistically similar, the 277 Fury achieves comparable or superior energy levels with shorter cartridges, shorter barrels, and lighter firearms, highlighting the advantages of its high-pressure design.

This segment from Gun Talk Radio features Aaron Olger from Hodgdon Powder discussing the critical importance of using verified reloading data. He strongly advises against substituting powders without established data, highlighting the risks of unsafe pressures and velocities. Olger emphasizes Hodgdon's commitment to rigorous testing in their ballistics labs to provide accurate data for consumers via their website, hodgdonreloading.com.

This video provides a complete process for zeroing and 'doping' any rifle, focusing on gathering ballistic data quickly without a chronograph. The instructor details a method applicable to both gas-operated firearms like the AR-15 and bolt-action rifles. A key technique discussed is the usefulness of a 36-yard zero for AR-15 platforms, enabling accurate point of aim/point of impact out to approximately 300 yards. This approach is presented as a reliable solution for shooters who lack access to chronographs.

This video provides a comprehensive consistency and reliability test of Remington .22 LR Golden Bullet ammunition, fired from a Taurus TX22. The test includes chronograph data for 64 rounds and a gel test for 6 rounds to assess terminal performance. The presenter, an experienced firearms instructor, notes the ammunition's reliability with no failures to fire, though some velocity variations were observed. The gel test revealed inconsistent penetration depths and no expansion, with projectiles tumbling in some instances.

This video details a comprehensive test of 225gr Hornady BTHP Match subsonic 300 Blackout ammunition across two different barrel lengths (8.5-inch SBR and 16-inch rifle) using Accurate 1680 and Reloader 7 powders. The instructor meticulously outlines the process of developing and testing loads, focusing on velocity, function, and accuracy to identify optimal subsonic performance.

This video details the reloading and ballistic testing of 200gr Sierra Match King bullets in 300 Blackout. The instructor, with extensive experience in reloading and ballistics, evaluates two powders (IMR 4227 and IMR 4198) across two different firearms (8.5-inch and 16-inch barrels). The testing focuses on velocity, group size, and firearm function, providing data to help viewers select optimal loads for subsonic 300 Blackout applications.
