10mm Auto | How Much Does Barrel Length Matter? Chronograph Testing Using 3.8”, 4.5” and 5” Barrels

This video demonstrates the impact of barrel length on muzzle velocity using .38 Special ammunition. A 1.8-inch barrel Ruger LCR and a 6-inch barrel Ruger GP100 were tested. The results show a significant velocity difference between the two barrel lengths, highlighting how barrel length affects projectile speed.

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This guide details how to estimate muzzle velocity without a chronograph, a crucial step for accurate long-range shooting. It leverages factory ammo data and barrel length adjustments as a starting point, then refines the estimate through 'truing your dope' with a ballistics app and live fire. The Precision Rifle Network hosts provide practical, expert advice for shooters seeking to optimize their ballistic solutions.

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 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 demonstrates the impact of barrel length on bullet velocity using AR-15 platforms. A practitioner with technical knowledge showcases data collected via a ballistic chronograph, comparing velocities from 7.5-inch, 11-inch, and 14.7-inch barrels. The objective demonstration highlights significant velocity gains with increased barrel length, particularly between shorter configurations.

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.
