Then, I bought a 22 rifle close to a month ago and it still isn't here. Bought 3 boxes of Remington hollow points for it around the same time and that ammo isn't here, either. The 22 rifle was in stock but there was a notice they were shipping so much as orders came in, the shipping would be delayed. I think the rifle will eventually get here and the ammo is from Cabela’s so I think it will come some time.
The United States has a virus and is throwing up daily. The source of the virus sits in the White House.
At close range, i.e. across the room, a too-heavy shotgun or too-heavy rifle can be "shot from the hip", much like sinking a cue-ball into a corner pocket. That will save your shoulder, and will make follow-up shots much easier.
A corner pocket is about 4.5 inches. The center mass kill zone on a man-size target is at least a 10" or 12" dinner-plate wide. Even if you miss the heart/lungs, getting gut-shot with 12-guage buck-shot or slug might not kill immediately, but I suspect the attacker's priorities will shift substantially.
