No expert here but shot an AR, 9 milli pistol,44 magnum, and a 30 carbine from ww2 or Korea. That 30 carbine is powerful. AR was like whatever. The genie is out of the box folks. Gun control never works.

5.56mm M193 = 1290 ft-pounds
9x19mm NATO = 430 ft-pounds
45 ACP MIL SPEC = 349 ft-pounds
7.62x39mm Soviet o1943g = 1500 ft-pounds
30 Carbine = 967 ft-pounds
44 Magnum = 971 ft-pounds
30-30 = 1826 ft-pounds
7.62mm NATO M80 = 2450 ft-pounds
30-06 (WW2 30M2) = 2570 ft-pounds
5.56mm has almost twice the effective range of 30 carbine, though the original bullet weighed only half as much.
Recoil as perceived by the user is somewhat subjective, and is much influenced by weapon design. 5.56mm round (close to 223 Rem) was developed from the beginning to deliver a low recoil impulse, to improve control in full auto arms. The M16’s predecessor was designed with the same goal in mind.
