This video details a reloading experiment for the 6.5 Creedmoor cartridge using Reloder 15.5 powder with 130gr Berger Hybrid OTM Tactical bullets. The instructor, Johnny, meticulously documents the process, including component selection, overall length measurements, and progressive charge weight testing. Despite initial baffling velocity inconsistencies, the latter half of the test yielded excellent accuracy and tight standard deviations, suggesting potential for this powder/bullet combination in lighter weight classes for the Creedmoor.

This video details the process of reloading 6.5 Grendel ammunition for a hog hunt, focusing on the 129gr Nosler Accubond Long Range bullet. The instructor tests two powders, IMR-4166 and AR-Comp, across various charge weights, meticulously documenting the reloading steps, chronograph data, and group sizes at 100 yards. The goal is to develop an accurate and effective hunting load, with a particular emphasis on bullet performance and powder selection.

This video investigates significant velocity variations in 300 Blackout subsonic loads, specifically 147gr with Accurate 1680 powder. The presenter replicates a commenter's findings where powder position within the case dramatically affects muzzle velocity, with swings up to 200 ft/s observed. This phenomenon is linked to inconsistent ignition, particularly in low-charge-weight, high-capacity cartridges. The testing involved comparing CCI BR4, SNB, and Federal AR Small Rifle Match primers, shooting rounds with powder settled horizontally versus vertically (powder towards the primer).

This video details the comprehensive process of preparing 6.5 Grendel brass for precision reloading and initiating load development. It covers meticulous case cleaning, resizing with a focus on controlled shoulder bump, trimming, and deburring. The instructor then moves into initial powder charge determination, emphasizing case capacity and the use of AR Comp powder, before outlining the setup for both Optimal Charge Weight (OCW) and ladder testing methodologies. The process includes setting up for consistent overall length and determining the distance to the lands for safe and effective load development.
