Best Bang for the Buck: 10mm Auto with Berry's

This video demonstrates the process of testing a handloaded 10mm cartridge featuring a 165gr Sig V-Crown JHP bullet and 9.0 grains of Hodgdon Longshot powder. An experienced handloader uses a Caldwell chronograph to measure velocities and calculate muzzle energy from two different barrel lengths (3.78" Glock 29 and 5" 1911), providing objective ballistic data.

This video analyzes real-world handgun use in bear defense incidents, drawing lessons from the Amoland database. Key takeaways include the importance of firearm accessibility, the effectiveness of warning shots against bears, the potential need for spare ammunition, and the higher threat posed by brown bears. It also discusses the performance of calibers like .44 Magnum and 10mm Auto, emphasizing that hitting the target is paramount.

Sully from Line 45 outlines seven essential calibers for gun owners to stockpile in anticipation of future ammunition shortages, emphasizing their specific roles and the current market conditions. The video highlights the importance of proactive stocking for calibers like 300 Blackout, 308 Winchester, 10mm Auto, 12 Gauge, 22 LR, 223 Remington/5.56 NATO, and 9mm Luger, detailing their performance characteristics and availability challenges.

This live stream emphasizes the critical importance of dry fire training for improving firearm proficiency, highlighting its cost-effectiveness and safety. The instructor, a certified NRA pistol instructor with over 40 years of experience, discusses various firearm calibers, maintenance practices, and the benefits of reloading. He also touches on the advantages of red dot sights and the effectiveness of 10mm for self-defense and hunting.

This video from Line45 discusses why smart preppers are diversifying their ammunition stockpiles away from the dominant 9mm caliber in 2026. Instructor Ted emphasizes logistics like weight, volume, and cost per round over online caliber debates. He breaks down the advantages of calibers like .22 LR for training and small game, .380 ACP for concealed carry availability, .40 S&W for its overlooked supply chain, 10mm Auto for outdoor threats, .357 Magnum for revolver flexibility, .45 ACP for predictable performance, and 5.7x28mm for high capacity and low recoil.

The video discusses the best calibers for self-defense, advocating for .357 Magnum for revolvers due to its power, barrier penetration, and practiceability with .38 Special. For semi-automatics, .40 S&W is recommended over 9mm for better performance, while acknowledging 10mm as potent but potentially too much for many shooters. The host also briefly touches on sighting in iron sights and red dots.

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.
