In reply to the discussion: The .223 A Very Deadly Bullet [View all]Jackpine Radical
(45,274 posts)The advantage, besides the light recoil (which makes it more suitable for auto fire), is that the ammo is much lighter than the 7.62 Nato round (known as the .308 in civilian use). The bullet is a dinky little 43 grains iirc, as opposed to 150 grains for the 7.62 military load.
A lot of GI's believed this myth about hitting someone in the finger & blowing his arm off. Not true. It's just a .22 bullet with a muzzle velocity of about 3200 fps. Compare that to, say, the .220 Swift, which fires that same bullet at about 3800 fps muzzle.
The .308 fires its 150-grain bullet at about 2700 fps at the muzzle by way of comparison. A .30-30 fires that .30-cal 150 gr. bullet at about 1900 fps, iirc.
For deer, gimme a .30-06 or .308 any day.
All figures are from memory & only as accurate as my incipient dementia will permit.
