This video presents a gel test of Wolf Gold 55gr Full Metal Jacket ammunition fired from a 16-inch Rock River carbine with a 1:9 twist rate. The test demonstrates the fragmentation characteristics of the FMJ round, comparing its performance to Lake City M193. While effective for general use and potentially for 'stacking deep,' the instructor suggests better-suited options for home defense due to the FMJ's longer wound channel.

This video presents a gel test of Brown Bear 55gr Soft Point 223 Remington ammunition fired from a 16-inch Rock River carbine with a 1:9 twist. The test reveals significant disruption and fragmentation, with the core retaining its jacket. While the performance is deemed decent for its price point, the instructor advises against it as primary home defense due to potential quality control issues with Russian steel-case ammunition and its tendency to not obturate as well as brass-cased rounds.

This video presents a ballistic gel test of Hornady 223 Remington 55gr GMX ammunition fired from a 16-inch Rock River carbine with a 1:9 twist rate. The test reveals significant expansion, a large temporary stretch cavity, and a penetration depth of 21.4 inches. While the ammunition shed one fragment and had a short neck, its rapid expansion and disruption capabilities are highlighted as desirable characteristics, potentially attributed to its 'barrier blind' design.
