This guide, presented by an experienced instructor from Palmetto State Armory, details how barrel twist rate significantly impacts .300 Blackout ammunition stability. It explains that faster twists (1:5) are ideal for heavier subsonic rounds, while slower twists (1:7) are better for lighter supersonic rounds. The video demonstrates live-fire testing to illustrate these performance differences, aiding shooters in selecting the appropriate barrel for their preferred ammunition type.

This entry details the manufacturing adaptations Indumil made to produce the Cordova pistol, drawing heavily on their experience with the Galil rifle. Expert insights highlight the strategic reuse of tooling and material specifications, including forged and milled steel for the slide and a 1:8 barrel twist rate derived from Galil production. The use of injection molding for polymer components also reflects leveraged expertise.

This guide details building a precision long-range rifle using a Bergara Premier Barreled Action. It covers component selection, including stocks, chassis, and triggers, and emphasizes testing various ammunition types for optimal sub-MOA accuracy. The information is presented with the authority of an experienced reviewer with significant trigger time on precision platforms.

This guide, presented by GUNBROS staff, details the trade-offs between using a .22 LR conversion kit in a standard AR-15 and purchasing a dedicated .22 LR AR-15 rifle. Key considerations include budget, accuracy differences due to barrel twist rates (1:14-1:16 for .22 LR vs. 1:7-1:9 for 5.56/.223), and potential fouling issues with Direct Impingement systems when using .22 LR ammunition. While conversion kits offer a budget-friendly entry, dedicated platforms are recommended for optimal performance and reliability.

This video delves into the specific engineering behind a firearm's pinpoint accuracy, focusing on barrel specifications and gas block design.
