An evil black rifle with the thing that goes up will put 30 .223 caliber projectiles in the air with 30 pulls of the trigger. A shotgun with an eight-round capacity will put 72 .30 caliber projectiles in the air with eight pulls of the trigger. That’s something that shocks the gun prohibitionists.
In close quarters, I’ll opt for eight pulls every time.
Longer than 90’ (distance from home plate to first) go with the semi-auto rifle.
