I have slugs. They must be aimed at center mass. My weapons have several target assist in addition to iron sights, beads etc. Laser dot, reflex sight dot etc.
Double ought can do the same job Slugs can do in typical home defense ranges. I have triple ought as my first experiment to be a alternative to slugs. When I am cleared to shoot after lens arrive, I will experiement with triple aught.
Double OO is very good against humans and dogs, you dont really have to aim TOO much, just enough to get the job done.
My mindset tends to be a knuckle dragger to the extreme. When ammuntion double aught is good enough for dogs back home, I want triple aught in case of BEARS... BIG bears....
My expectations of triple aught is to deliver almost the same energy into center of target without seeing that target's spine going through the side wall of my home and splashing back two inches of gore onto me at 12 feet.
My problem is that the designated kill area has a water heater to the left of it., frankly considering the damage that will be done with a home invasion done proper against my home, I dont give a &^% about that water heater on the other side of two layers of drywall.
The wife at her refuge room will be firing slugs down that hall and she can use the iron sights on her mossy much better than that fancy techno laser stuff. She was taught to shoot USMC and knows how to make corrections to put rounds on target.
Think about triple aught as 8 .40 or .45 caliber bullets stuffed into a shotgun shell. Then think about my very short 18 inch barrel with the Improve choke. My range is less than 20 feet before the spread gets too wild.
Not too many wives I know are able to do this. Maybe one is enough
