Videos tagged with Ammunition Grain Weight

This video from SilencerCo, presented by Beaver, investigates the necessity of a suppressor booster on various Glock models when using lightweight suppressors like the Spectre 9. The testing covers Glock 19 Gen 3, 43, 26, and 17 Gen 3, using 115, 124, and 147 grain ammunition, comparing direct thread mounts against booster assemblies. The findings highlight how suppressor weight and firearm design (especially barrel length and action type) impact cycling reliability and ejection patterns, with subcompacts showing particular sensitivity to direct threading.

This guide details AR-15 zeroing techniques, emphasizing that 'mission dictates gear.' Instruction from experienced firearms professionals Kaya and Jason covers POA/POI mechanics, and analysis of common zeros (25, 36, 50, 100-yard) with considerations for barrel length and ammunition. The 50-yard zero is highlighted as a versatile and 'foolproof' option for most users.

This video provides an expert-level explanation of ammunition grain weight, detailing its significance for projectile performance. Instructors Kai and Jason break down how grain weight impacts velocity, stability, penetration, and ballistic coefficient across various calibers like 5.56 NATO, 300 Blackout, and 9mm. They emphasize that grain weight is a critical factor for selecting the right ammunition for specific applications, from long-range precision to self-defense scenarios, and how it interacts with barrel twist rates.

This video delves into the intended purposes of various firearms, distinguishing between defense, competition, collector, and duty roles. It explores the nuances of firearm design, such as the impact of barrel length, trigger characteristics, and materials (steel vs. polymer) on a gun's suitability for different applications. The discussion also touches on ammunition selection, including grain weight and its effect on performance, and the practical considerations for duty firearms like maintenance, cost, and reliability.
