The “practical” application for these shells is not 3 gun, hunting, or training. It is across a room home defense. It will kill 40-70ish pound pigs across a large corral trap. It holds a decent pattern at 5-7 yards( federal holds a great pattern) and I am comfortable with it for that purpose.I agree, and he is clearly prejudiced against mini shells and the Opsol adapter. Lol, if it ain't Remington green and white box, he doesn't approve.
