Videos tagged with Group Size Measurement

This video explores the impact of suppressors on firearm accuracy. The instructor demonstrates that while a suppressor can alter the point of impact, it does not inherently reduce accuracy. Specific group sizes are measured and compared, highlighting the potential for tight groupings even with a suppressor attached.

This video provides an in-depth review of the Geissele 18" SPR cut-rifled barrel. It details the barrel's unique features, including the phased raid gas system and larger thread diameter. The review includes detailed bench inspection, headspace gauging, and extensive range testing with four different ammunition loads, presenting group sizes, velocities, and AZE scores for each.

This video demonstrates an accuracy test of the Henry Supreme rifle chambered in 300 Blackout. The reviewer fires multiple shots and measures the resulting group size, achieving a commendable 0.850 inches. The assessment highlights the rifle's accuracy potential for this caliber.

This video details a 100-yard .22LR accuracy challenge using a CZ 457 Varmint Precision Chassis rifle and CCI Standard Velocity ammunition. The shooter demonstrates the process of zeroing, firing groups, making sight adjustments, and analyzing results using a range app. The challenge focuses on achieving tight groups at extended distances with common rimfire ammunition.

This video provides a comprehensive review of a TRIARC 16-inch AR-15 upper receiver. It details technical specifications, conducts bench inspections including BCG gauging and barrel measurements, and performs a range test with three different ammunition types (PMC XTAC M193, IMI Razor Core 77gr, Hornady 73gr ELD Match). The review includes 30-shot group analysis, velocity data, and comparative performance metrics, offering insights into the upper's accuracy potential with various loads.

This video details a comprehensive accuracy testing process for a custom Sig Sauer P365 build, focusing on selecting the optimal carry ammunition. Lead Firearms Instructor Roger Barrera demonstrates how different ammunition types and weights impact group sizes at 25 yards, emphasizing the importance of finding what a specific firearm 'likes' for maximum accuracy and reliability. The guide includes insights into recoil mitigation with the Radian Ramjet comp and the performance of the Vortex Defender CCW optic.

This live chat covers various reloading topics, including powder recommendations for 5.56, shotgun shell loading for turkey season, and discussions on load development methodologies like mean radius versus extreme spread. The speaker, an experienced firearms instructor, shares insights on barrel fouling, bullet selection for different applications, and the challenges of statistical significance in load testing.

This guide demonstrates the process of firing a 5-shot group with a Henry .22 Magnum rifle from a bench rest. It highlights the importance of consistent shot placement and concludes with measuring the group size using digital calipers, achieving a 1.0-inch group at 100 yards. The demonstration emphasizes accuracy testing for this lever-action firearm.

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.

The Caldwell Target Camera offers shooters a way to view their target from a distance, connecting wirelessly to a smartphone app. It provides a 720p HD feed, allowing for precise shot placement analysis and group size measurement within the app. The system is designed for convenience and durability, featuring a weather-resistant build and a portable carrying case.

This video provides a comparative test of Berger 140gr match-grade ammunition against Hornady 140gr match-grade ammunition and custom handloads. The host, Joel from Precision Rifle Network, details chronograph data, including average velocity, standard deviation, and extreme spread, alongside group sizes at 100 yards. The Berger ammunition demonstrated a 0.5-inch group with a 7.8 SD and 21 ES. The video also covers extended range testing out to 550 yards, confirming first-round impacts with the Berger loads.

This video details the process of reloading 6.5 Grendel ammunition using heavier 140-grain Hornady Match BTHP bullets, a less common choice for this caliber. The instructor, with apparent experience in reloading and firearms, outlines the steps for preparing brass, selecting powders (Accurate 2520 and Alliant Power Pro 2000 MR), seating bullets to magazine length, and conducting test firing. The focus is on achieving accuracy and understanding the performance of heavier bullets in the Grendel, including velocity and potential stabilization issues.
