This video compares the ballistic performance of 223 Remington and 7.62x39mm steel-cased soft-point ammunition fired from 16-inch barreled AR-15 and AK-47 platforms, respectively. The test involves chronographing velocities and observing terminal effects in ballistic gel, noting fragmentation, expansion, and penetration differences between the two calibers. The presenter, an experienced firearms instructor, provides insights into the practical implications for hunting and self-defense.

This video, presented by firearms expert Ian McCollum of Forgotten Weapons, delves into the mechanics and historical application of gain twist (progressive twist) rifling in small arms. McCollum explains how this rifling technique, characterized by an increasing rate of twist from breech to muzzle, aims to improve bullet stability and prevent jacket separation, citing examples from early revolvers to modern high-powered handguns. The discussion highlights its use in specific firearms like the Carcano 1891 and S&W 460 X-frame, while also touching upon its effectiveness and historical context.

This video details a ballistics gel test of Silver Bear 7.62x39 125-grain soft point ammunition fired from an Arsenal SGL21 rifle with a 16-inch barrel. The test aimed to debunk the myth that Russian soft point rounds do not expand well. The results showed significant expansion and fragmentation, with jacket separation occurring.
