Bulletproof testing cinder blocks

Ted from Line 45 discusses the evolving landscape of handgun calibers, highlighting how shooters are increasingly looking beyond 9mm for specific needs. The video explores 30 Super Carry for increased capacity in compacts, 5.7x28mm for flat trajectory and speed, 10mm for significant stopping power, 357 SIG for barrier penetration, and 22 TCM for rifle-like velocity in a pistol platform. The discussion emphasizes that while 9mm remains a standard, newer calibers offer solutions for specialized applications.

This video explores the growing trend of shooters replacing 9mm with alternative calibers in 2025, driven by advancements in ammunition and firearm technology. The presenter, Ted from Line 45, details the strengths of .30 Super Carry for concealed carriers seeking higher capacity in compact frames, 5.7x28mm for its flat trajectory and speed, 10mm for its significant power and barrier penetration, .357 SIG for its velocity and hard target performance, and .22 TCM for its rifle-like speed in a pistol platform. The discussion highlights how these calibers address specific needs that 9mm may not always meet, emphasizing performance, capacity, and specialized applications.

This video explores the practicalities and perceived importance of having a handgun and rifle that share the same ammunition. While acknowledging the convenience factor, the presenter argues that it's often overrated and can lead to compromises in firearm selection, particularly for hunting or specialized roles. The discussion touches on historical contexts, modern applications, and potential scenarios like the apocalypse, ultimately suggesting that distinct calibers for handguns and rifles can be more advantageous.

This video tests Velocias 9mm 96-grain solid copper hollowpoint defensive ammunition. The instructor evaluates its performance against a steel target, observing significant mushrooming and recovery of the projectile after a 3-inch dig. Further testing in a sand jug with a 2x6 backer shows the rounds do not penetrate the wood, indicating effective energy transfer and stopping power within this medium.

This video tests common household objects and vehicle components as ballistic cover against various calibers including .22 LR, 9mm, .223, 12 gauge, and 300 Blackout. The experiment uses ballistic dummies to determine if objects provide cover (stopping rounds) or concealment (not stopping rounds). Results indicate that most everyday items offer minimal to no effective cover against common firearm calibers, with only certain materials and calibers showing potential to stop rounds.

This video provides practical advice for preparing for potential societal collapse, emphasizing firearm readiness and essential supplies. The speaker, a self-described regular guy with no formal credentials, stresses the importance of owning a reliable rifle like an AR-15, stocking ammunition, and mastering marksmanship fundamentals. He also covers critical survival items including medical supplies, food, water, and fuel, advocating for a 'stay put' strategy over bugging out.

This video demonstrates the ballistic resistance of an excavator bucket against various firearm calibers, from .22 LR to .50 BMG API. The test, conducted by an experienced individual, shows that while smaller calibers cause minimal damage, larger rounds like the .50 BMG API can penetrate the bucket. The footage provides visual evidence of impact effects and the destructive potential of different ammunition types.

This video tests the penetration capabilities of various calibers against a large pine tree, culminating with a .50 BMG API round. Surprisingly, even powerful rifle rounds like 5.56mm and 7.62mm, as well as handgun rounds like 10mm and .44 Magnum, failed to fully penetrate the tree. The .50 BMG API round, while charring the entry point, also did not exit the back of the tree, demonstrating the significant stopping power of a substantial tree trunk.

This video from Yee Yee Life features an experienced host testing the ballistic penetration of various calibers, from .22 LR to .50 BMG, in an Intex swimming pool. The host demonstrates proper firearm safety and provides detailed measurements of bullet penetration depths, offering unique insights into how different rounds interact with water as a medium. The results highlight significant variations in penetration based on caliber and velocity.

This video tests the ballistic resistance of a Secret Service Suburban window against various calibers, from .22 LR to .50 BMG. While smaller calibers and even a 10mm and .44 Magnum were stopped with varying degrees of damage, the window was eventually penetrated by a .50 BMG sniper rifle round. The testing provides a clear demonstration of the limits of armored vehicle glass against high-powered rifle threats.
