(2,708 posts)ezra: Level III hard armor should stop multiple .223/5.56mm unless they impacted exactly the same spot on the armor ... That could only be done with careful shooting from a braced rifle and a perfectly stationary, compliant target at close range.
... you're right handgun muzzle velocity is less & kinetic energy about 65% of one coming off an AR15, but with precision impacts several handgun .223s could still pierce the bpv; additional fear is that with a handgun an undetected shooter can get much closer to police (& all soft targets), thus compensating somewhat for the less energy on impact from the AR15.
It seems that up close, repeated braced pistol .223s would be more accurate than repeated braced .223s from an AR15 fired from a distance, due external ballistics from distance (or could be).
The interval between braced rapid fire handgun bullet hits could be what, a fifth of a second to a half second? momentum transfer from one or two 55 grainers usually isn't enough to push a man off, mainly his own reflex reaction, so dunno about much change in a stationary, perhaps sitting, target, after a second or two.
And up close, shooter's aim is better &, as with all pistols, makes for a better shot for unprotected parts; solid hitting an unprotected part up close with a .223 is generally either a delayed death sentence or an amputation.
ezra: No centerfire rifle whatsoever is stopped by IIIA or below.
(aside) Some could be stopped with a tangential incident angle, obliquely.
ezra: ..any centerfire rifle from the .22's up through .308 penetrate at close range like M855 does... What exactly do you intend to ban?
What the BATFE advises banning; I wasn't totally up to speed on this, in fact I schooled on it just this morning serendipitously via politifact: This was rated MOSTLY FALSE: Says "President Obama is using executive actions to impose gun control on the nation, targeting the top-selling rifle in the country ... with a ban on one of the most-used" assault rifle bullets.

(politifact): ...hes talking about the ATFs plan for one particular type of bullet -- a 5.56 mm "green tip." It is found in SS109 and M855 cartridges, and its one of the more popular types of ammunition in America, experts told us. But this February, the ATF announced a proposal to remove an exemption that allowed gun owners to use this particular kind of ammunition. The agencys reasoning? It can pierce the sort of body armor often worn by police, and it can be fired from a handgun.
The ammunition isnt new, nor is its ability to pierce body armor. What is new is that gun manufacturers are making handguns that use a 5.56 mm "green tip."
That, ATF says, violates the Law Enforcement Officers Protection Act of 1985 that aimed to ban armor piercing bullets.
"The AR-based handguns and rifles utilize the same magazines and share identical receivers," the ATF wrote.. "These AR-type handguns were not commercially available when the armor piercing ammunition exemption was granted in 1986. To ensure consistency, upon final implementation of the sporting purpose framework outlined above, ATF must withdraw the exemptions for 5.56 mm "green tip" ammunition, including both the SS109 and M855 cartridges."
Final concern is, what is the green tip bullet needed for? the armed tyranny invasion?
