The Best Home Defense Caliber (9mm vs .300 Blackout)
This video compares 9mm and .300 Blackout for home defense, analyzing terminal ballistics, platform versatility, and cost. .300 Blackout offers superior energy and range, especially with subsonic loads and suppressors, making it effective in short-barreled rifles. 9mm remains a viable option due to its affordability, lower recoil, and reduced over-penetration risk, particularly in pistol or PCC platforms.
