Unless one's life depended on it; you ALWAYS use the round that's designated on the weapon's barrel or reciever. If it's marked .223 (5.56mm) then that's what you use. If you still feel curious about it, avoid to do so, or the round might not be correctly fired and could damage the gun or hurt you
The M-16 round is a 5.56 mm round. It's smaller than an AK-47 round (7.62mm) A 5.56 mm will kill easily! Hoo-ah
A M16 and a 9 mm pistol are the two of the main guns that the US infantry uses today.
The M16 is an assault rifle that is a .223 caliber / 5.56 mm. like any weapon it is only as accurate as its shooter, <><><> It can be very accurate.
The root diameter of an M16 thread, which refers to the smallest diameter of the threaded portion, is approximately 13.5 mm. This value can vary slightly based on the specific thread class and manufacturing tolerances, but it generally remains close to this dimension for standard M16 threads.
A 9 mm round out of a Glock 17 is 1148 feet per second
The answer is simple. AK can break through concrete, M16 can't. Run over AK with Humvee, it still works, M16 will break to pieces. Bury an AK in dirt, still works fine. Bury an M16, doesn't work. Submerge an AK in water, works just great. Submerge an M16 in water, jams. The M16 is more accurate that the AK47. It has a higher muzzle velocity. It has a much higher rate of fire. The weight of a soldier's supply of rounds is much less with the M16. The AK has substantial impact at 300 - 600 meters. The M16 has very little impact at that range. This is because the AK uses 30 calibre (7.56 mm) bullets and the M16 uses 22 calibre (5.56 mm) bullets. The small diameter causes the bullet to slow from air resistance quite rapidly. The M16 has a problem (as do all rapid-firing ultralight assault rifles) of overheating when firing long bursts. One method that some American instructors taught their soldiers to destroy weapons that had to be left behind was to fire a full 20 round clip and then push the barrel against the ground. The barrel will warp. The AK is much more resilient.
No. 9mm and .40 are not interchangeable.
The 5.56 AP round penetrates 12 mm armor plate of 300 HB at 100 m. The 7.62 AP round penetrates 15 mm armor plate at 300 m.

Depending on the depth of the round brilliant cut, the measurement can be estimated at about 8 mm at the girdle.
Most if not all countries' armed forces use either the 5.56x45 or the 7.62x51 mm cartridge, if not both.
