.308 Win and 6.5 Grendel - Lapua Scenar bullets with IMR 8208 XBR

This video details the process of finding an accuracy node for 6.5 Grendel ammunition using H335 powder and 123gr ELD-M bullets from factory seconds. The instructor chronographs various powder charges fired from an 18-inch Bear Creek Arsenal barrel to identify a velocity node, then selects a charge weight for load development and accuracy testing. Initial results indicate the barrel may not be inherently accurate, prompting a discussion about potential future load development with different powders.

This video provides a methodical test of various .308 Winchester bullet types against steel plates of increasing thickness, from 1/4 inch to 1 inch. The host, demonstrating high authority in amateur ballistic testing, uses a custom rifle and MagnetoSpeed V3 chronograph to record velocities and penetration depths. Key findings highlight how bullet construction and weight significantly impact performance, with specialized AP rounds showing superior penetration compared to standard hunting and match bullets.

This video provides an expert-level deep dive into the 6mm AR cartridge, presented by a recognized authority on AR-15 optimization. It covers the cartridge's technical specifications, history, and ballistic performance, demonstrating sub-MOA accuracy at 500 yards and engaging targets out to 750 yards. The build features high-end components like an X-Caliber barrel, Geissele trigger, and Leupold optic, highlighting its suitability for Precision Rifle Series (PRS) competition and hunting applications for those willing to handload.

This video demonstrates the process of re-zeroing an AR-10 rifle chambered in .308 Winchester at 100 yards. The instructor highlights the importance of securing optic turrets after adjustments to prevent them from backing out due to recoil, a problem he experienced previously. The guide covers firing initial shots, observing impact, and making precise adjustments using MIL-based turret values to achieve a dead-center zero.

This video demonstrates a creative and destructive approach to pumpkin carving using various firearms and ammunition. The presenter uses handguns, rifles, and shotguns to 'carve' faces and obliterate pumpkins, showcasing the effects of different calibers and projectile types. The session also includes a demonstration of a SOG machete for additional pumpkin destruction.

This YouTube video focuses on a 6.5 Grendel rifle chambered in 6.5 Grendel, specifically testing the 90-grain Varmageddon load. The testing involves chrono measurements taken from two different barrel lengths: an 18-inch barrel and a 16-inch barrel. The video likely explores the ballistic performance and velocity differences between the two barrel configurations with this particular ammunition.

This guide details a successful method for removing a stuck cartridge case from a firearm barrel using hydraulic pressure generated by a high-pressure grease gun. The technique, demonstrated by Johnny's Reloading Bench, involves a custom adapter and motor oil to hydraulically force the case out. The video highlights the importance of proper tools and high pressure, showcasing a successful extraction that saved a valuable Krieger barrel.

Instruction from a firearms enthusiast and reloader on preparing and sizing 300 Winchester Magnum brass. The video details the challenges of reloading for this caliber, including the long throat of the Thompson Center Compass rifle and the importance of proper neck tension and shoulder bumping. It covers selecting collets, setting up sizing dies, using specialized tools for case maintenance, and determining optimal seating depths for accuracy.

This video provides an in-depth review and performance test of the Vortex Diamondback Tactical 6-24x50 rifle scope, presented by Johnny, an experienced gear reviewer. The review covers technical specifications, a practical tracking test (box test) at 100 yards, and optical quality comparisons with other Vortex models. Johnny highlights the scope's First Focal Plane (FFP) reticle and its value proposition for its price point, while also noting limitations in optical clarity compared to higher-end models.

This video provides a comprehensive guide to reloading .22-250 Remington ammunition, focusing on a Remington Model 788 with a Douglas barrel. It details component selection (brass, bullets, primers, powders), case preparation, powder charging, bullet seating, and initial range testing. The instructor emphasizes accuracy and velocity, aiming to develop loads suitable for varmint and deer hunting, while also highlighting potential challenges with certain components and the firearm's specific characteristics.
