Understanding Firearm Calibers 🔫 | A .45 is not what you think | Calibers Explained

This video tests the ballistic resistance of a 1kg rubber mallet against various calibers of ammunition, from .22 LR to .308 Winchester. The mallet demonstrates significant resistance, absorbing or deflecting most rounds, but is ultimately penetrated by the .308. The test highlights the surprising durability of the rubber mallet against firearm projectiles.

The video explains that grip depth differences between common handgun calibers like 9mm, .40 S&W, .357 Sig, and .45 ACP are minimal. It notes that some larger magnum rounds may require slightly larger grips. The discussion also clarifies that Glock's SF models refer to short frames, not slim frames, and their grip size was adjusted based on caliber accommodation.

This video demonstrates how easily bullets can deflect when fired through obstacles like thick brush. Instructor Kyle from Classic Firearms tests common calibers including 9mm, 5.56x45mm, 7.62x39mm, .308 Winchester, and .45 ACP at 25-35 yards. The results show significant deflection, tumbling, and altered trajectories, highlighting the importance of understanding bullet behavior in real-world hunting or self-defense situations.

This video provides expert guidance on stockpiling ammunition, emphasizing pattern recognition of market shortages rather than panic buying. It details seven calibers that consistently become scarce, offering specific recommendations for reserve quantities for each, distinguishing between training and defensive loads. The advice is presented from the perspective of a firearms instructor focused on practical preparedness.

This video from Line45, hosted by Ted, outlines seven critical ammunition calibers Americans should stockpile to prepare for potential ammo shortages, referencing patterns seen in 2020 and anticipating a 2026 crunch. Ted emphasizes the importance of having sufficient defensive and training ammunition for various firearms, detailing why specific calibers disappear first during panic buying and the factors influencing supply chain disruptions. The advice is geared towards intermediate shooters and gun owners concerned with preparedness.

This video demonstrates a ballistic test using pumpkins to gauge the penetration power of various calibers, from .22 LR up to .50 BMG. The experiment, conducted by an experienced individual, showcases how different firearms and rounds interact with a soft barrier, providing a visual understanding of projectile energy and stopping power. The results highlight significant differences in penetration capabilities across the tested calibers.

This guide, presented by experienced shooter CajunBoyJake, demonstrates the superior stopping power of a 12-gauge shotgun with #00 buckshot over a 9mm pistol for home defense scenarios. Through live-fire comparison, it highlights the significant difference in immediate incapacitation potential, advising viewers to prioritize shotguns for this role.

CajunBoyJake, a knowledgeable practitioner, advocates for a defensive home defense strategy prioritizing cover and communication over aggressive room clearing. He highlights that the practical reach difference between a shotgun and a handgun in a defensive posture is less significant than overall length suggests. The guide emphasizes securing a position, calling 911, and holding a choke point if movement is required.

This guide details the bump fire technique for semi-automatic rifles, as demonstrated by CajunBoyJake. It explains how to use recoil and finger tension to achieve rapid firing rates without full-auto conversion. The technique involves using a belt loop for consistent backward pressure while pushing the rifle forward, allowing the trigger to 'bump' against the finger with each recoil cycle. Proper safety and understanding of semi-automatic function are emphasized.

This video, presented by CajunBoyJake, directly compares the effectiveness of a 9mm handgun versus a 12 Gauge shotgun for home defense. Through live demonstrations using a Glock 17 and Winchester Super X 00 Buckshot on a simulated target, the video visually illustrates the significant terminal ballistics advantage of the shotgun, strongly advocating for its use in home defense scenarios over handguns.
