Are They Reliable? | 6.5 Grendel & 6GT Update

This range report from Brownells demonstrates the performance of a 6.5 Grendel AR-15 build at distances up to 500 yards. The video highlights the cartridge's energy on target compared to 5.56 and discusses its trajectory, requiring significant adjustments at longer ranges. It confirms the 6.5 Grendel's continued relevance for shooters seeking more power than standard intermediate cartridges.

This video details load development for a 6.5 Grendel using BLC2 powder and 123gr Hornady ELD-M bullets. The presenter focuses on achieving tight five-shot groups from a Diamond Back barrel, aiming for sub-MOA accuracy. The testing reveals promising results with a specific charge weight, highlighting the importance of meticulous load tuning for precision shooting.

This video provides an in-depth review of new Lapua 6GT brass, detailing its precise manufacturing specifications and performance in competition and hunting scenarios. F-class John from Ultimate Reloader highlights the brass's consistency in length, weight, and neck wall thickness, emphasizing its suitability for both 'no-turn' chambers and traditional reloading. The review includes performance data from Sig Cross and Bergara rifles, offering insights into the 6GT cartridge's place between the 6.5 Creedmoor and 6 Dasher.

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 presents a 100-yard ballistic test comparing 5.56x45mm NATO, 6.5 Grendel, and 7.62x39mm ammunition. The host measures muzzle velocity and energy, then re-measures at 100 yards to determine velocity and energy loss. The results highlight how bullet weight, ballistic coefficient, and diameter affect downrange performance, with the 7.62x39mm demonstrating surprising energy retention despite a lower BC than the 6.5 Grendel.

This comparison between 6.5 Grendel and 300 Blackout highlights the Grendel's superior range performance due to higher energy and velocity, making it ideal for distances beyond 200 yards. The 300 Blackout is better suited for close-quarters engagements, such as woodland hunting up to 200 yards. Ballistic data confirms the Grendel retains significantly more energy at longer ranges.

This video features an expert firearms instructor demonstrating trigger pull weights on two distinct rifles. He assesses a two-stage trigger on a precision rifle at approximately 3.5 lbs and contrasts it with an extremely light 1 oz trigger on an F-Class rifle, highlighting significant differences in trigger feel and weight.

This guide compares the CMMG Resolute 200 series rifles in 5.56 NATO and 6.5 Grendel, drawing on expert insights from Precision Rifle Network. It details their respective optimal ranges, zeroing methods, and ballistic performance, highlighting the 6.5 Grendel's superiority for medium-to-long-range precision applications and the 5.56's effectiveness for closer engagements. The instruction emphasizes practical ballistics calculations for extended range shooting.

This guide details the process of testing various factory 6.5 Creedmoor ammunition loads through a Bergara B14-HMR rifle. It covers setting up chronographs, live fire procedures, and analyzing data for velocity, extreme spread, and group sizes. The testing protocol, as demonstrated by the technical and objective speaker, aims to provide comprehensive performance insights for different ammunition types.

This guide details a long-range shooting technique for the SKS rifle using open sights, as demonstrated by a highly authoritative instructor. It covers zeroing at 100 yards, making precise sight adjustments, and extending accuracy to 600 yards by accounting for ballistics and subsonic effects. The instructor emphasizes practical application and data-driven adjustments for success.
