This video features an expert-level penetration test comparing the 10mm Auto and .357 Magnum cartridges. Conducted by Kentucky Ballistics, the test utilizes a Glock 20 for the 10mm round (180gr FMJ) and a Smith & Wesson 686 for the .357 Magnum round (125gr FMJ), both fired into wooden boards. The .357 Magnum demonstrated superior penetration, stopping on the 15th board compared to the 10mm's 11th board.

This video from SHOT Show 2026 introduces the DoubleTap SnakeShot Magnum, a powerful ammunition line designed for more than just pest control. Featuring a unique payload of shot pellets and a hard-cast wadcutter, these loads exceed 1200 fps and offer significant penetration. The demonstration highlights their effectiveness on various targets and discusses their versatility for backcountry defense against predators.

This guide details the process of loading a 5 Star Firearms L6-.357/38 Speed Loader, a crucial accessory for revolver owners. The video, presented by TheYankeeMarshal, demonstrates how to efficiently load 6 rounds of .357 Magnum or .38 Special ammunition into the speed loader. It highlights compatibility with popular revolvers like the Colt Python, Smith & Wesson 586, and 686, emphasizing its utility for quick reloads at the range or in defensive scenarios.

This entry details the use of 5 Star Firearms speedloaders, specifically the L6-357/38 model, for .357 Magnum and .38 Special revolvers. The video highlights a technique for loading cartridges into the speedloader at an angle for proper seating and mentions an unexpected bonus speedloader included with an order. The content is presented by TheYankeeMarshal, an experienced individual familiar with firearm accessories.

This video provides an expert-level comparison between the .44 Magnum and .50 Action Express calibers, featuring a Magnum Research Desert Eagle and a Ruger Super Redhawk. The host, demonstrating high authority, conducts a series of tests including penetration through lumber, steel, sand, and concrete, followed by ballistic gel testing with hollow-point rounds. The analysis highlights differences in muzzle energy, penetration, and wound channel, ultimately questioning the cost-to-performance ratio of the .50 AE.

This video provides an in-depth, experimental comparison between .223 Remington and 5.56x45mm NATO cartridges, utilizing a chronograph and various barrier materials. The host, demonstrating high expertise through empirical testing, reveals significant performance differences, particularly in barrier penetration, with 5.56x45mm NATO generally outperforming .223 Remington.

This video from Banana Ballistics explores the surprising lethality of "less lethal" shotgun ammunition. Through rigorous testing with ballistic gel and plywood, the host demonstrates that rounds like bean bags and high-velocity .410 rubber buckshot can cause significant damage, challenging the common perception of these rounds as entirely non-lethal. The testing highlights the importance of understanding ammunition performance beyond its intended classification.

This video provides an objective comparison of 9mm Luger, .40 S&W, and .45 ACP calibers through a series of rigorous tests including lumber, sand, concrete, and ballistics gel. The host, leveraging specialized equipment like a Garmin Xero C1 Pro chronograph and digital calipers, presents data on velocity, penetration, and expansion. While .40 S&W showed competitive performance in some tests, the analysis concludes with a preference for 9mm due to its higher capacity and lower recoil, highlighting the importance of practical considerations beyond raw ballistics.
