How Berger Broke the 6mm Barrier (120gr Hybrid & Bryan LItz)

This video provides an in-depth review and testing of the new Sierra 105gr MatchKing (SMK) target bullet. Host Gavin Gear from Ultimate Reloader, demonstrating significant expertise, tests the bullet across three different 6mm cartridges (6mm Creedmoor, 6mm ARC, and 6.5x47 Lapua) in custom rifles. The testing includes lab analysis of bullet consistency (weight, diameter, length) and long-range accuracy at 706 yards. The video highlights the importance of twist rate for stabilizing these heavier bullets and presents detailed load data and group results for each tested platform.

This video details a progressive reloading process for Precision Rifle Series (PRS) ammunition using a Dillon 550 press. It emphasizes achieving sub-half MOA accuracy and a velocity standard deviation of 10 FPS or better. The guide covers load development strategies, including the use of a precision powder dispenser for incremental testing, and highlights the benefits of ball powders like Winchester Stable 6.5 for consistent charges on a progressive press. The presenter, Gavin from Ultimate Reloader, shares his expertise in optimizing loads for competitive shooting.

This video provides an expert-level ranking and analysis of eight top long-range rifle calibers for 2026, focusing on their performance attributes, best uses, and pros/cons. It covers calibers like the 6mm Dasher for precision competition, the versatile 6.5 Creedmoor for general long-range use and hunting, the powerful .338 Lapua Magnum for extreme distances, and the .280 Ackley Improved for magnum performance in a standard cartridge. The .308 Winchester is also discussed for its historical significance and continued capability at moderate long ranges.

This guide details the setup and performance of a custom 6mm GT rifle, presented by an expert shooter. The 6mm GT is compared to the 6mm Dasher, highlighting its improved magazine feeding. The rifle features an Impact 737R action, MDT Premier stock, and Athlon Cronus BTR Gen II scope, chambered in 6mm GT with a 26-inch Bartlein barrel. With Berger 105 Hybrid loads achieving 2940 fps, the rifle demonstrates exceptionally low recoil, enabling shooters to spot their own impacts at 1,000 yards. The expert emphasizes the stability and accuracy achieved during long-range engagements.

This video provides an in-depth review and testing of Hornady's new Aeromatch 105gr 6mm bullets. F-class competitor John from Ultimate Reloader details the bullet's aerodynamic design, availability in bulk packs (500 and 3000 count), and seamless integration into existing loads. He presents detailed measurements of length, weight, and diameter, highlighting their tight tolerances. The testing phase includes powder charge development with Varget, culminating in impressive group sizes, with one group measuring in the .13 MOA range. The review emphasizes the bullet's consistency and performance for competitive shooters seeking an edge.

This episode of Gun Talk Radio features Tom Gresham and John Snow, Shooting Editor of Outdoor Life, discussing the 6mm Creedmoor cartridge. They delve into its history and highlight its effectiveness as a competition cartridge, particularly for Precision Rifle Series (PRS) shooting. The conversation also touches on how the stress of competition can translate to improved performance in field applications. The description also provides information on how to tune into the live radio show and access Gun Talk's various media platforms.

This video details the comprehensive manufacturing process of brass rifle casings by Peterson Cartridge. It covers the transformation of raw brass cups through multiple drawing, annealing, washing, heading, trimming, and tapering stages. The process emphasizes precision, quality control through extensive automated and manual inspection, and specialized treatments like neck re-annealing and anti-tarnish coating to ensure match-grade performance.

This guide details essential brass preparation steps beyond basic decapping and sizing for improved reloading accuracy. It covers cleaning, primer pocket uniforming, neck chamfering and deburring, and neck brushing. The video emphasizes that even new brass can benefit from these processes to ensure consistent bullet seating and optimal performance. The presenter, F-class John from Ultimate Reloader, highlights chamfering and deburring as critical steps that should not be skipped, regardless of time constraints.

This video debunks the myth that solid copper bullets require extremely high velocities for effective hunting performance. Through ballistics gel testing and analysis of 7 PRC loads using Barnes TTSX and LRX bullets, Gavin Gear demonstrates excellent expansion and weight retention across a wide velocity range, including lower velocities equivalent to longer ranges. The testing highlights the versatility and effectiveness of modern monolithic copper projectiles for various hunting scenarios and legal requirements.

This video details extreme pressure testing of the 6mm ARC cartridge using both a bolt-action rifle and an AR-15 platform. The experiment pushes the limits of Alpha Munitions brass with 8208 XBR powder, achieving velocities exceeding factory specifications and even 6 Creedmoor. The testing culminates in destructive attempts using a fast-burning pistol powder in an AR-15, demonstrating the significant forces involved and the potential for catastrophic failure. The presenter, Gavin Gear, emphasizes that these tests are for research only and should not be replicated due to extreme danger.
