6.5 Grendel | Which Powder Is The Fastest in 16” and 18” Barrels?

This video details the process of reloading 6.5 Grendel ammunition using Hornady 123gr SST bullets and Hodgdon CFE 223 powder. It demonstrates weighing a 31.5-grain powder charge and measures the resulting velocities from 16-inch and 18-inch barrels, achieving 2503 fps and 2526 fps respectively. The inspection of spent primers indicates high pressure, suggesting this charge is near maximum.

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 YouTube video focuses on a 6.5 Grendel rifle chambered in 6.5 Grendel, specifically testing the 90-grain Varmageddon load. The testing involves chrono measurements taken from two different barrel lengths: an 18-inch barrel and a 16-inch barrel. The video likely explores the ballistic performance and velocity differences between the two barrel configurations with this particular ammunition.

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 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 video provides a head-to-head accuracy test between the Ruger 10/22 and the Marlin Model 60, both chambered in .22 LR. The host, an experienced shooter, details the test methodology, including ammunition types and a consistent 25-yard range. The comparison highlights key features of each rifle, such as magazine capacity and aftermarket availability, concluding with a visual presentation of the shot groups.

This video details a comprehensive ballistics gel test for various .38 Special loads fired from a Smith & Wesson 642 snub-nose revolver. The expert instructor analyzes bullet expansion, penetration, and wound channels, offering critical insights into ammunition performance for self-defense. Key takeaways include the importance of bullet design for reliable expansion in short barrels and safety considerations for handloading .38 Special ammunition.

This guide details a head-to-head ballistic gel test comparing 9mm Luger +P and .40 S&W ammunition, as demonstrated by an experienced firearms reviewer. The test involved firing specific loads through denim barriers into gel blocks, measuring velocity and penetration, and analyzing recovered projectiles. The .40 S&W HST showed more dramatic expansion, while the 9mm +P achieved deeper penetration. The comparison highlights trade-offs between terminal performance, capacity, and recoil in compact firearms.

This video demonstrates the initial live fire of a .50 Beowulf AR-15 platform rifle, featuring a side-charging upper receiver and a Vortex red dot optic. The host, identified as a firearms enthusiast and content creator, showcases the loading process, firing, and the significant impact of the large caliber rounds on steel targets at an outdoor range. The demonstration highlights proficient firearm handling and range safety awareness.
