Hornady 12th Edition Reloading Manual

This video provides an in-depth look at the 7mm Sherman Short (7S) cartridge, focusing on its performance in short-action rifles. It details the cartridge's design, including its 40-degree shoulder angle and optimized bullet placement for maximizing case capacity and velocity. The content compares its performance to the 7 PRC, discusses suitable bullets and powders for reloading, and highlights key components for building a rifle chambered in 7S. The presenter, Gavin Gear from Ultimate Reloader, shares his extensive experience with Sherman Wildcat cartridges.

The new Hodgdon website consolidates all their previous branded sites and the Reloading Data Center into a single, user-friendly platform. This new site is optimized for mobile devices, making it easier for reloaders to access data from their reloading bench or the range. Users can compare different loads and powders, finding data for pistol, rifle, and shotshell applications.

This guide details the setup, calibration, and operation of the RCBS Chargemaster Link reloading scale. It emphasizes the importance of warming up the scale, ensuring it is level, and performing accurate calibration using the included weights. The video demonstrates both manual and app-controlled dispensing, highlighting the 'Auto' mode for efficient high-volume reloading and the necessity of using reliable load data.

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 episode features a deep dive into the 6mm MAX cartridge with its creators, Brian and Clark. The discussion covers its development as a 5.56 replacement, its performance advantages over other cartridges like 6mm ARC and 6.5 Grendel, and its suitability for various applications from CQB to long-range shooting. They address common misconceptions, technical challenges, and the ongoing evolution of the cartridge, emphasizing its potential for military adoption and civilian use.

This video provides an in-depth guide to developing accurate rifle ammunition, emphasizing the critical relationship between rifle and ammo. It details the importance of meticulous record-keeping, the scientific method for load development, and careful selection of bullets, powders, and cases. The instructor stresses that accuracy is paramount over velocity and that tailoring loads to a specific rifle is key to achieving sub-MOA performance.

This video details the comprehensive manufacturing process of brass rifle casings by Peterson Cartridge. It covers the transformation of raw brass cups through multiple drawing, annealing, washing, heading, trimming, and tapering stages. The process emphasizes precision, quality control through extensive automated and manual inspection, and specialized treatments like neck re-annealing and anti-tarnish coating to ensure match-grade performance.

This guide details essential brass preparation steps beyond basic decapping and sizing for improved reloading accuracy. It covers cleaning, primer pocket uniforming, neck chamfering and deburring, and neck brushing. The video emphasizes that even new brass can benefit from these processes to ensure consistent bullet seating and optimal performance. The presenter, F-class John from Ultimate Reloader, highlights chamfering and deburring as critical steps that should not be skipped, regardless of time constraints.

This video debunks the myth that solid copper bullets require extremely high velocities for effective hunting performance. Through ballistics gel testing and analysis of 7 PRC loads using Barnes TTSX and LRX bullets, Gavin Gear demonstrates excellent expansion and weight retention across a wide velocity range, including lower velocities equivalent to longer ranges. The testing highlights the versatility and effectiveness of modern monolithic copper projectiles for various hunting scenarios and legal requirements.

This video details extreme pressure testing of the 6mm ARC cartridge using both a bolt-action rifle and an AR-15 platform. The experiment pushes the limits of Alpha Munitions brass with 8208 XBR powder, achieving velocities exceeding factory specifications and even 6 Creedmoor. The testing culminates in destructive attempts using a fast-burning pistol powder in an AR-15, demonstrating the significant forces involved and the potential for catastrophic failure. The presenter, Gavin Gear, emphasizes that these tests are for research only and should not be replicated due to extreme danger.
