Rifled vs Smooth Bore Barrel

This video critiques AI-generated content regarding firearms, highlighting inaccuracies in explanations of vertical grips, pistol optics, and short-barreled shotguns. The presenter, with apparent expertise in firearms, corrects the AI's misconceptions about weapon handling, ballistics, and legal regulations. Key takeaways include the reasons for reduced vertical grip use on modern AR platforms due to evolving grip techniques, the actual reasons police departments may not issue red dots, and the physics behind bullet trajectory and shotgun performance.

This expert guide from Ted of Line45 debunks the myth of the 12 gauge being the 'most powerful' round by critically defining power and comparing it to rifle calibers. It details the performance of slugs and buckshot, emphasizing their respective strengths and weaknesses at different ranges, and highlights the 12 gauge's true advantage: its unparalleled versatility and ammunition availability.

This guide details the setup and accuracy testing of a Mossberg 12-gauge slug gun, featuring an Accufire optic and Hornady SST sabot slugs. It covers 100-yard accuracy demonstrations and explains the mechanics of sabot projectiles. The content is presented with high authority by Scott from Kentucky Ballistics, emphasizing the 'old school powerhouse' capabilities of the slug gun.

This guide clarifies the critical difference between rifled slugs and sabot slugs, emphasizing that rifled slugs are intended for smoothbore barrels and sabot slugs require rifled barrels. Firing the wrong type of slug through a barrel can lead to reduced accuracy and potential damage. Expert instruction from Brownells highlights these distinctions for safe and effective shotgun use.

This video provides an expert demonstration comparing shotshell patterns from smoothbore and rifled barrels using a Mossberg 500. Experienced shooters Barry and Eric from Iraqveteran8888 showcase how rifling significantly degrades pattern performance for both birdshot and buckshot at defensive ranges due to centrifugal force. The demonstration highlights practical insights into shotgun ballistics and effective ammunition selection.

This video compares the penetration capabilities of homemade 12-gauge slugs against factory-produced slugs when fired at a car door. The test reveals that factory slugs create a larger hole and exhibit greater penetration, while homemade slugs, though powerful, cause less damage and do not fully penetrate the car door. The speaker notes the difference in weight between the slugs tested.

This video from DemolitionRanch, hosted by Matt Carriker, explores the capabilities of high-powered, regulated air rifles like the AirForce Texan SS and Sam Yang Dragon Claw. Carriker demonstrates their impressive power, accuracy, and surprisingly quiet operation due to integrated suppressors, highlighting a legal loophole where these airguns and their suppressors are not subject to NFA regulations. The content showcases ballistics testing and comparisons, emphasizing the expert knowledge of the host in firearms and related legalities.

This video features Nicholas Irving, a former Special Operations sniper, demonstrating and discussing various high-powered firearms. Irving, author of 'Way of the Reaper,' shares insights on sniper rifles like the Barrett M107A1 and SR-25, discusses the recoil of the S&W 500 Magnum, and tests the penetration capabilities of different calibers against an engine block. The content highlights practical applications and the effectiveness of these weapons in tactical scenarios.

This video demonstrates the dangerous consequences of firing incorrect ammunition calibers in firearms. Experienced instructor Matt Carriker shows how .380 ACP in a 9mm firearm and 9mm in a .40 S&W firearm can lead to cycling failures and severe brass deformation due to improper headspacing. The experiment highlights the critical importance of using the correct ammunition for each firearm to ensure safe operation and prevent damage.

This video from DemolitionRanch, featuring firearms expert Matt Carriker, tests the ballistic resistance of Flex Tape when used as improvised body armor. The experiment involves layering Flex Tape onto cardboard and testing its effectiveness against .22 LR, 5.7x28mm (FN PS90), and 9mm (CZ Scorpion Evo 3 S1) rounds. The results demonstrate that even extensive layering of Flex Tape is insufficient to stop common firearm calibers, highlighting the importance of proper ballistic materials.
