This video details an advanced reloading experiment comparing the impact of different sizing dies on cartridge runout and accuracy for the .223 Remington caliber. The instructor meticulously tests Lee, Redding, and Mighty Armory dies, along with various expander types, to quantify their effect on concentricity. The results are then correlated with 10-shot group performance at 100 yards, revealing surprising insights into how die choice can influence precision, while also highlighting the potential impact of barrel heat on group consistency.

This video compares the performance of 168gr Sierra Match King and Hornady Match BTHP bullets in .308 Winchester using Alliant AR-Comp powder. Both bullets demonstrated excellent precision, with the Sierra SMK achieving a 0.33-inch group at 2797 fps and the Hornady Match yielding a 0.42-inch group at 2753 fps. The test highlights the effectiveness of AR-Comp powder for accurate rifle loads and provides detailed load data for reloaders.

This guide details a method for creating a custom bullet seating stem for .223 Remington 75gr Hornady BTHP bullets, addressing issues with inconsistent seating and bullet marking. The process involves using JB KwikWeld epoxy to form a precise mold of the bullet's ogive within a standard seating stem. This technique, demonstrated by a high-level reloading expert, ensures better bullet alignment and more consistent overall length (OAL) in reloaded ammunition.

This video details the process of disassembling M855A1 ammunition to analyze its components and then uses those components for reloading experiments. The instructor demonstrates bullet pulling techniques, powder charge analysis, and bullet measurements. Reloading tests are conducted with different powders and bullets, followed by live-fire accuracy and velocity testing. The analysis highlights the challenges and potential outcomes of reloading with military surplus components.

This video reviews the Sierra GameChanger 165gr Tipped GameKing bullet in .308 Winchester, focusing on its performance in hunting scenarios. Testing involved developing handloads with Alliant AR-Comp powder and evaluating accuracy in a Tikka T3 Lite and an Aero Precision AR-10. Terminal ballistics were assessed via ballistic gel, showing impressive expansion and weight retention.
