While speaking in Wilkes-Barre, Pennsylvania, on Tuesday President Biden said, “The bullet out of an AR-15 travels five times as rapidly as a bullet shot out of any other gun.”
Ironically, on June 30, 2022, Field & Stream did an in-depth look at the “Five Fastest Rifle Cartridges” and the two AR-15 rounds, .223 and 5.56, did not even make the cut.

Thanks gundog. I haven’t checked Shotgun News in a long time.
That’s a blessing that it missed everything.
God was saving me for something... what, I don’t know.
Well, gee, doesn’t everyone know that’s what the “15” stands for? “1” are all other rifles. “5” (times as fast) is the AR-15.
Hic!
Just a dumb ass pile of shlt.
“...not even 5X faster than a .45 (Long) Colt. The slowest center fire cartridge I’m aware of.” [Afterguard, post 46]
45 Colt was one of the speediest handgun rounds of its day: 255gr bullet traveling 855 ft/sec, delivering over 410 foot-pounds of kinetic energy. At the time, 44 Russian (father of 44 Special) fired a 246gr bullet at some 770 ft/sec, producing over 320 foot-pounds of kinetic energy. All other American handgun cartridges of the time were less powerful. Same was true of the great majority of handgun cartridges made in Britain and on the Continent.
Even today, standard-velocity 45 Colt is quite respectable. The introduction of dual-chambered revolvers (45 Colt & 410 shotshell) by Taurus and Smith & Wesson has helped.
“The 30.06 round has about 4 times the hitting power of the .223 cartridge. It was way more than was needed. Which is why they went to a smaller, lighter, weaker cartridge.” [FLT-bird, post 40]
“The .30-06 came into being when horses were still commonplace on the battlefield and that was a consideration in its development. In that regard, its power was not considered overkill.” [Joe 6-pack, post 61]
If horse-killing figured in 30-06 development, the fact doesn’t show up much in the historical record.
Long-range performance of rifle cartridges was a much greater consideration in the 1890s than it is today.
30-06 was a modification of an earlier round, the 30-03. The latter fired a 220gr round-nose bullet at a velocity of about 2300 ft/sec. It was discovered that increased range was possible if a lighter, sharper-pointed bullet was used; the new round had a slightly shorter case neck and fired a 150gr bullet at a velocity of 2700 ft/sec. For several years after, M1903 rifles were modified: 0.25 inch was trimmed off the breech of the barrel and a new chamber was reamed. Sights were replaced with a recalibrated elevation ladder, graduated out to 2700 yds.
The modifications were not over.
After World War One, machine gun performance at extreme ranges was judged to be the key consideration; this led to the adoption of the 30M1 round, which fired a 172gr boat-tail bullet.
Several years after, the M1 autoloading rifle designed by John C Garand was introduced.
It was found that the desired velocity could not be attained with the 30M1 cartridge in the M1 Garand rifle, so a new round was adopted: 30M2, which fired a 153gr flat-base bullet at a velocity of 2750 ft/sec.
This last loading was used all through WW2, and Korea, and as long as the M1 Garand remained in inventory. Max range was still pretty good: about 3450 yds.
Most other major powers introduced cartridges of about the same performance in the period 1888-1905. Loadings were changed in similar ways.
Can’t speak to hitting power. But the 5.56x45mm NATO round develops about half the kinetic energy of the 30-06 in its 30M1 loading. It also weighs only half as much, and rifles chambering it are more controllable in full-auto fire, which was a primary consideration.
Kinda like owebama and bayonets.
