that’s just not ballistically possible
5.56 moves over 30in at 530y with 10mph wind. 338 does so at 1000y. double the distance but inaccuracy increases with the square so it’s more like 4x harder to hit or 4x less windage. plus 223 goes subsonic at 800-900 anyway. 338 is 1-2km round all day long. 77gr vs 300gr. energy retention plays a factor too extending the distance of 338 for hunting while 223 is like a 22lr at 300y so it better hit something important.
i think a 223 and 300wm is all someone ever needs (besides a pistol and shotgun the least)
Given alot of shooters routinely shoot the 22lr beyond 300yds in competition, the 223 is a 'cannon'. If you want to really hurt your brain, look up CRPS king of the 22lr mile. Starts at 100m and goes out to 700m

The original 5.56 and even the 62gr versions use bullets that are NOT designed to shoot far well. The bullets you are quoting are military choices which are mag constrained and not designed to fly as far as possible. The heavy bullet options in the 22cal rival the BCs of bigger calibers and speed is speed. LR shooters can single load or modify mags to suit, and use bullets that fly well up to and sometimes past subsonic speeds.
Yes, I shot a 223 80gr out to 1mile and it worked (bullet chosen had no issue going subsonic).... in near dead calm conditions. Drift would have been massive but that is just a number that can be calculated (just ask rimfire PRS shooters how much wind they hold way the heck out there) Accuracy of well tuned rifles/ammo, don't degrade on a windy day... even if the driver is having doubts.
I did chase a 338LM with 250gr Lapuas all the way out to 1400yds (ran out of real estate) with my 223/heavy bullets. Obviously, the 338 landed with way more energy. Drifted less BUT... the 223 helds its own just fine.
If you just want to ting off steel, many small options work just fine. If you want to break something, bigger and heavier certainly helps.
YMMV

PS for a frame of reference, palma/TR shooters (jackets and slings) are trying to hit the V bull which is MOA at 1000yds/900m. FTR is trying to hit a 1/2 MOA V bull at the same distance. I competed with the 223 for a few seasons in FTR. Did well at mid range but the drift was too challenging for my limited skills at LR.. But there are shooters who have done well at the further distances vs the 308.
Drift is just a number, IF you know what the wind speed is, dial and send it.
