Federal Personal Defense Buckshot

Thanks for posting all of these videos, you definitely have me reconsidering what I have loaded for home defense. Which round out of all of the ones you tested so far would you keep loaded for home defense? The groups on this load were impressive.

Thank you for your work. Very helpful. I saw that you tested this personal defense ammo in both 12g #00 (1.5” spread at 5 yards) and 20g #4 (6” spread at 5 yards. I’m new to shotguns and curious why the spread is so different between these two. Is this normal due to gauge and or buckshot size?
