55 Grain Will Get You Killed #shorts
This video debunks the effectiveness of 55 grain 5.56mm ammunition for self-defense, highlighting its limitations compared to specialized defensive rounds. It explains that 55 grain FMJ is primarily for practice and requires longer barrels (20 inches) to achieve effective fragmentation, performing poorly from shorter barrels (10.5 inches). The speaker recommends heavier loads like 62 grain, 70 grain, or 77 grain for defensive applications.
