Videos tagged with Neck Sizing

This video demonstrates the functionality of the Lee Precision Collet Die for neck sizing and the Micrometer Bullet Seater. The collet die is highlighted for its ability to resize only the neck of a cartridge case, extending brass life, especially when shooting in the same firearm. The micrometer seater offers precise control over bullet seating depth, ensuring consistency for handloaded ammunition.

This guide details the necessity of sizing new primed brass, even if it appears undamaged. Kent Sakamoto of Hodgdon Powders explains that bulk packaging can cause neck distortions, impacting accuracy. The process involves adjusting sizing dies correctly, lubricating cases, and resizing to true up the neck, ensuring consistent performance and proper chamber fit. It's recommended to size all new primed brass to achieve optimal reloading results.

This video details the process of neck sizing brass using a Lee Collet Die for improved ammunition accuracy. The instructor emphasizes the importance of proper brass preparation as the 'launch platform' for consistent internal ballistics. He contrasts standard full-length sizing with neck sizing, highlighting the benefits of the Lee Collet Die's unique mandrel and collet system for uniform neck sizing without lubricant, which he claims leads to superior accuracy and longer brass life.

This video details the process of reloading .223 Remington ammunition using Vihtavuori N133 powder and Hornady 40gr V-Max bullets. It extensively covers the comparison between a Lee Collet neck sizing die and a Mighty Armory full-length sizing die, including the intricacies of setting up the Lee Collet die and the surprising discovery of incompletely fire-formed brass. The instructor also discusses load development, velocity testing, and the impact of brass fire-forming on accuracy.

This video details the reloading and live-fire testing of 223 Remington ammunition using 40gr Hornady V-MAX bullets. The presenter, drawing on his grandfather's successful loads, tests two popular powders, Hodgdon H.335 and Alliant Power Pro Varmint, at two charge weights (26.5gr and 27.0gr). The testing is conducted in a re-chambered Remington 700 BDL Varmint Special with a 1:14 twist barrel, focusing on accuracy and velocity data.

This guide details the initial brass preparation for reloading the 6.5 PRC cartridge. It covers inspecting and lubricating brass, performing neck and full-length resizing, troubleshooting stuck cases, and preparing cases for priming. The process highlights the importance of proper die setup and lubricant selection for successful reloading.

This episode delves into the critical aspects of reloading ammunition for ultra-long-range (ULR) and extreme long-range (ELR) shooting. Achieving extreme precision requires meticulous attention to detail, including tight control over powder charge velocity standard deviations (ideally under 10 fps), precise bullet weight sorting, and exact bullet seating depth to manage internal case volume and pressure. Factors like bullet jump to the lands and cartridge runout are also crucial for consistent aerodynamics and accuracy at extended distances.

This video details the initial steps in cloning the military MK 248 Mod 1 300 Winchester Magnum round. The host meticulously analyzes factory ammunition, measuring critical dimensions, weighing components, and documenting powder charges. He also conducts initial range tests to establish baseline velocity and accuracy, highlighting the importance of understanding factory specifications and potential safety concerns due to higher-than-SAAMI pressure.

This guide explains the function and setup of L.E. Wilson bushing dies for reloading. It details how bushing dies offer adjustable neck sizing by using interchangeable bushings, which is crucial for managing varying brass neck thicknesses across different manufacturers and calibers. The process involves measuring the cartridge neck, selecting a bushing (typically 0.001" to 0.003" smaller than the loaded cartridge neck diameter), inserting it into the die, and setting the stem to allow for slight float. This method helps improve case concentricity and consistency, especially for precision shooting applications.

This video details the process of reloading .308 Winchester ammunition using 208-grain Hornady ELD-Match bullets and Hodgdon Varget powder. The instructor demonstrates brass preparation through neck sizing, primer pocket cleaning, and priming. He then proceeds to weigh powder charges and seat bullets to a specific overall length, adhering to Hornady manual recommendations. The video also covers initial testing and observations regarding bullet stabilization in different rifle twist rates.

This guide details the process of reloading 7.62x54R ammunition using the budget-friendly Lee Rifle Loader. It covers essential steps from brass inspection and decapping to priming, powder charging, and bullet seating, emphasizing neck sizing limitations and the importance of OAL measurement. The speaker, demonstrating high expertise, also highlights crucial accessories and specific considerations for surplus rifle calibers.

This guide details advanced cartridge case preparation techniques for handloaders seeking higher accuracy. It covers essential steps like inspection, trimming, deburring, and weight sorting, progressing to specialized processes like neck turning and neck sizing. The instruction emphasizes the importance of uniform case capacity and concentricity for precision shooting, drawing on the expertise of GunBlue490.
