Testing the accuracy of 5.56 ammo I Sellier & Bellot

Clint Morgan discusses the relevance of short-barreled rifles (SBRs), arguing they are not obsolete despite longer barrels offering greater velocity and range for cartridges like 5.56. He highlights SBRs' advantages in close quarters, vehicle operations, and home defense due to their compact size, contrasting them with the longer barrels needed for optimal 5.56 performance. The discussion touches on specific platforms like the Mark 18 and M4, and mentions the potential for advanced accuracy from newer designs like Blackout Defense's.

This guide details a comprehensive testing methodology for specialized ammunition, specifically focusing on a detonator-loaded bullet. It outlines a step-by-step process for evaluating its performance against various targets, from soft tissue simulants to hard materials, using standard FMJ rounds as a baseline. The expert-level approach emphasizes meticulous documentation, velocity measurement, and analysis of impact effects to understand the unique destructive capabilities of such ammunition.

This video tests the ballistic resistance of a Soviet-era hammer against various calibers. While smaller rounds like .22 LR caused minimal damage, larger calibers like 9mm, 7.62x39mm, .223 Remington, and .308 Winchester inflicted progressively more damage, with the .308 ultimately causing significant structural failure to the hammer's handle.

This video by Ted from Line45 outlines seven essential calibers Americans should stockpile to prepare for potential ammunition shortages, citing patterns observed in past events like the 2020 crunch. The advice focuses on calibers that disappear first due to high demand from various user groups, supply chain vulnerabilities, and production limitations. The instructor emphasizes maintaining separate stashes for training and defensive ammunition for each caliber.

This video from Polenar Tactical showcases an extreme test of a Protection Group Denmark U-line ESAPI XL ballistic plate. The plate, rated NIJ Level 4 (0101.06) and designed to stop a .30-06 M2 AP round, is subjected to non-standard testing including drops, fire, and multiple high-impact rifle rounds. The demonstration highlights the plate's robust construction and protective capabilities beyond typical testing parameters, as assessed by experienced tactical gear reviewers.

This video from Polenar Tactical, featuring expert Žiga, demonstrates rigorous testing of Protection Group Denmark's U-line ESAPI XL Level 4 ballistic plates against unconventional threats beyond standard NIJ 0101.06 testing. The expert guide outlines a comprehensive testing methodology, from baseline rifle threats to extreme scenarios like grenade fragmentation and multi-shot rifle impacts on damaged plates. The assessment highlights the plate's exceptional performance even when compromised, offering valuable insights for tactical gear users and armor manufacturers.

This entry details the safe handling of the T G-67 M-SOFT training hand grenade, as demonstrated by Ziga from Polenar Tactical. It emphasizes the critical role of the safety pin and spoon mechanism in preventing accidental detonation. The M-SOFT variant is likely for airsoft or training purposes, highlighting the importance of understanding device types for safety.

This expert guide from Polenar Tactical demonstrates the critical technique for applying a CAT-style tourniquet to control severe limb hemorrhage. The instruction emphasizes correct placement ('high and tight') and windlass application to stop bleeding, acknowledging the necessary pain involved. The video highlights that despite discomfort, proper tourniquet use is a life-saving measure.

This guide details the operation of the TAG 18 Smoke White grenade, as demonstrated by Polenar Tactical. It covers the basic mechanical components and the activation process, emphasizing its use for concealment or signaling.
