I’m no expert, but the velocity is as important as the diameter. Short barrels stay NFA, whatever. But 5.56 nato is apples to a 22lr apricot
Does the same job when introduced to a head.
Big time, just need close range.
Yep. These people that train to hit targets a 500 yards are cool and all but that probably won't be the engagement range of the up coming war. And unless they are training to hit moving targets all those hours and money will not be very useful

The .22-250 Remington is a very high-velocity (capable of reaching over 4000 feet per second), short action, .22 caliber rifle cartridge primarily used for varmint hunting and small game hunting. Though it finds occasional use on deer, this is not recommended.[2] Some jurisdictions prohibit the use of cartridges smaller than 6mm (e.g., .243 Winchester) for deer hunting. This cartridge is also sometimes known as the .22 Varminter or the .22 Wotkyns Original Swift.[3] Along with the .220 Swift, the .22-250 was one of the high-velocity .22 caliber cartridges that developed a reputation for remote wounding effects known as hydrostatic shock in the late 1930s and early 1940s.[4][5]

Hydrostatic shock is the controversial concept that a penetrating projectile (such as a bullet) can produce a pressure wave that causes "remote neural damage", "subtle damage in neural tissues" and/or "rapid incapacitating effects" in living targets.
