Ammo Comparison: M855 v M193
From Ammo To Go:
Technically, both the M193 and M855 are military cartridges. Like most military surplus supplies, there are strict rules around civilian ownership of M193 and M855 ammunition. However, the average Joe can get his hands on loads nearly identical to this military ammo, even though that ammo may not be actual “mil-spec.†Some of these loads are even manufactured on the same lines that make ammo for the military at Lake City’s Army Ammunition Plant.
Judicial Watch Seeks ATF Docs On Ammo Ban
From Judicial Watch:
Judicial Watch announced today that it filed a brief in the United States District Court for the District of Columbia asking the court to order the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to produce more than 1,900 pages of records relating to the ATF’s proposed reclassification that would effectively ban certain types of AR-15 ammunition as armor-piercing.
ATF Director: “Any 5.56 Round a Challenge To Officer Safety”
From The Washington Examiner:
In a Senate Appropriations Committee hearing, ATF Director B. Todd Jones said all types of the 5.56 military-style ammo used by shooters pose a threat to police as more people buy the AR-15-style pistols.
“Any 5.56 round” is “a challenge for officer safety,” he said. Jones asked lawmakers to help in a review of a 1986 bill written to protect police from so-called “cop killer” rounds that largely exempted rifle ammo like the 5.56 because it has been used by target shooters, not criminals.
So the problem isn’t M855 but all 5.56 ammo? Sounds like they want to ban all ammunition.
ATF Backsdown on Bullet Ban
From The Washington Post:
Gun-rights supporters responded angrily. Right-wing media accused the Obama administration of an illegal move to restrict the Second Amendment. U.S. Rep. Bob Goodlatte (R-Va.) wrote a letter co-signed by 236 members of Congress to express their “serious concern.” Fifty-two senators also expressed their displeasure with the ATF’s proposal.
From The New York Times:
But in a Twitter post on Tuesday, the agency acknowledged the intense opposition to the change and said it would shelve the proposal for now.
“You spoke, we listened,†the post said. “@ATFHQ plans more study on the proposed AP Ammo exemption framework.â€
A statement on the agency’s website said the agency had received more than 80,000 opinions even before the comment period for the proposed regulatory change was due to end next Monday. The agency said the “vast majority of the comments received to date are critical†of the proposal.
“Accordingly, A.T.F. will not at this time seek to issue a final framework,†the statement said. “After the close of the comment period, A.T.F. will process the comments received†and “further evaluate the issues raised.â€

5.56 and .223 Ammo – Everything You Need to Know
Below are some direct links to an OUTSTANDING FAQ from The Ammo Oracle at AR15.com.
It is a very comprehensive collection of information on .223 and 5.56 ammo.
History and Basic Design of .223 and 5.56 Ammunition.
- What is the history behind the development of the .223/5.56mm round?
- What is the difference between 5.56×45mm and .223 ammo?
- Which should I be looking for in an AR15, a 5.56 NATO or .223 Remington chamber?
- What is the circle-cross stamp on some of my ammo?
- How can I tell if a round is SAAMI, U.S. military, or 5.56 NATO Mil-Spec?
- What is FMJ? JSP? JHP? FMJBT?
- What is “Ballistic Tip” ammo?
- What types of ammo has the US Military used in its M16s and M4s?
- What about Mk262 or Mk262 Mod1?
- What are the dimensional specifications for M855 and M193 casings?
- What is SS-109? Is it the same as M855?
- What type of ammo is current issue for US Military forces?
- Why did the US Military adopt M855 for the M16?
- So why don’t all US military units carry M855?
- Is all SS-109/M855 ammo marked with green bullet tips?
Performance of .223 and 5.56 Ammunition.
- I have my rifle zeroed with M855 ammo. Will any 62gr ammo shoot the same?
- Do M193 and M855 shoot to the same point of impact?
- Ok, what is all this stuff about rifle twists and different ammo?
- OK, that’s complex. Simple question: Can I fire M193 ammo in my 1:7 or 1:9 twist barrel?
- Can I fire M855/SS-109 in my 1:12 twist barrel?
- Will M193 be accurate in a 1:7 or 1:9 twist barrel?
- What twist rate do I want for my rifle?
- What about XM193 from Federal and Q3131a from Winchester? I have heard that some of these don’t meet military specifications, particularly with respect to sealant on the necks and primers?
- Holy earache Batman! This Q3131A/Lake City XM193 is really loud and it launches a FIREBALL from my muzzle! Everyone at the range is looking at me now. What gives?
- Military ammo has flash retardant, right?
- What sort of velocity and ballistics should I expect from military ammo?
- Will Military Ammo wear my favorite National Match/Elite Sniper/$5500 accurized AR rifle out faster?
- What is Moly? What’s it good for?
- Moly sounds hella-cool. I’m going to use it will all my rounds from now on!
Terminal Performance of .223 and 5.56 Ammunition.
- So which ammo is better, M193 or M855? And what is all this discussion about fragmentation? Are these dum-dum bullets?
- So, velocity is a critical component for the wound profile. How fast must the bullet be traveling when it hits its target in order to fragment reliably?
- At what range will M193 fragment? How about M855?
- So do both M193 and M855 fragment the same? How do their wound profiles compare to the FBI requirements?
- Isn’t 7.62 NATO much better for long range penetration than 5.56 anyhow? Why would I want to use 5.56 when I could send 7.62 downrange instead?
- Didn’t tightening the twist rate from 1:14 to 1:12 reduce the wounding potential of M193?
- If I increase spin or barrel twist, won’t that decrease wounding by making a round more stable in tissue?
- Does the 2,700 fps rule apply to all .223 and 5.56 ammo?
- That’s really complicated. Simple question: Why is M193 better than M855?
- But doesn’t M855 penetrate hard objects better than M193?
- I heard that M855 has had serious stopping problems in Afghanistan, and earlier in Somalia. Is this true?
- Is military ammo the best choice for defensive use?
- But what about specialty commercial rounds, like TAP, hollowpoints and softpoints? Aren’t they better than Mil-Spec ammo for defensive use?
- Won’t JSP and JHP rounds be safer indoors? Don’t I have to worry about FMJ rounds going through walls and hurting my family or others?
- I’m concerned about roving packs of zombies driving automobiles after the end of the world as we know it. Since, as everyone knows, you have to make headshots to kill zombies, what ammo should I be using to defeat auto glass and sheet metal?
- So are heavier rounds dead for self-defense purposes?
- What about using Wolf in defensive roles?
- Will M193/M855 penetrate a bulletproof vest?
- My department is considering using 10″ or 11.5″ barrels for our ARs. They are so cool, and everyone knows that all the real go-fast, high-speed, low-drag operators use SBRs. Plus, Robert DeNiro uses one in “Heat.” What’s the best ammo to use to poke big holes in the bad guys with these?
.223 and 5.56 Ammunition Testing
- Is Gelatin testing accurate or what?
- Where can I find reviews of various types of ammo?
- Why should I test new-production ammo? It should work, shouldn’t it?
- How do I make a professional looking/sounding range/ammo report of some ammo I liked/hated?
- What is “B & T Ammo Labs?”

- Do I want SS-109 or M855 then?
- What if I want more punch? What should I move up to from 5.56mm?
- Isn’t 5.56 too dangerous to use indoors? Shouldn’t I use a pistol or shotgun instead?
- What is “SHTF” ammo? What is TEOTWAWKI?
- What is the best M193 to get?
- But aren’t all M193 rounds the same? It’s a standard specification, right?
- What is with this goo and the dings on my Lake City Rounds? What is this discoloration on the necks of my Q3131A? Did someone take a blowtorch to it?
- What is the best M855 to get?
- Where can I get some M995 AP?

- Can tracers cause fires?
- What is the best round for hunting deer-sized game?

Ammunition recommendations from the authors of the AR15.com Ammo-Oracle.
Purchase and Storage of .223 and 5.56 Ammunition.

- Where did all the South African Battlepack Ammo go?
- I’m buying ammo for long-term storage and I have found some surplus ammo cheap. Should I buy that?
- So what should I be paying for ammo?
- I chambered a round in my AR and then unloaded it later. The primer has a small dent in it, apparently from the firing pin. Should I be worried about this? Won’t that cause a slam-fire? Should I switch to a Titanium firing pin?
- How do I store ammo properly?
- Where can I buy ammo cans?
- What is a stripper clip?
- What is a bandoleer?
- Where can I buy stripper clips, guides, bandoleers and related items?

- My wife just got one of those uber-cool vacuum food packers. I was thinking of sneaking into the kitchen and vacuum sealing all my ammo when she goes to watch the kids play soccer this weekend. What do you think?
- OK I’m hyperparanoid. Plus, vacuum packing is cool. Which vacuum packer should I use? How do I get started?
- Can I store ammo pre-loaded in magazines for an extended period of time? Won’t the magazine springs wear out and cause feeding problems? Shouldn’t I rotate my mags?
- Shouldn’t I be loading my mags with a few less rounds? If I load them to capacity doesn’t that cause reliability problems?
Legal questions.
- Isn’t against the Geneva Convention for the military to use hollowpoint or fragmenting ammo?
- Isn’t M855 ammo Armor Piercing (AP) and illegal to possess for non-law enforcement? Isn’t M855/SS-109 restricted to military/law enforcement use? Isn’t SS-109 illegal in Illinois?
- I am never going to use handload/law enforcement only/specialized rounds for self defense because that fact will be used against me in a criminal/civil proceeding to show I am a evil man/woman and be used to imprison/bankrupt me.
