I received about 100 rnds of M193 from a friend, and as I was loading it on stripper clips, I took a quick look and I noticed a round that was exactly the same length over all (case and bullet), same diameter case, same (well now that I know, slightly smaller) caliber bullet, it just had a lower shoulder I guess you could call it. I thought it was a messed up round, but when I took it out and examined it, I noticed that the headstamp read ".222 rem" I relized I had finally seen my first .222 rem round. Now the question:

Had I not been paying attention, and this got loaded into my firearm, what would have been the reprocussions? It appears that it has less powder and therefore would be less powerful that your standard 5.56 cartridge, so I'm assuming that nothing bad would have really happened, but has anyone ever shot .222 rem out of their AR?

I don't plan on shooting this round, it's going on my shelf, but I'm just curious.

Im not sure, but I think a .222 has more pressure than a .223. From the bottom of the case to the shoulder is alittle longet I believe.

lots of thing could have happened......all of them associated with excess headspace. if the extractor held it in place well enough to fire, it could have ranged from nothing to your upper coming apart and mag blown out from a ruptured case......all in all not something you want to try.

that's the .222 rem mag.......it would not have fully chambered in a .223/ 5.56

There are two rounds that carry the .222 nomenclature.

The .222 Remington also known as the 'Triple Duece'

&

The .222 Remington Magnum.

Look here for information.

They use the same diameter bullets, but neither is the same as the .223 Rem/5.56 NATO.

Don't forget the .222 Special.

I had to look that one up.

The .222 Special won out over the other two and soon became known as the .223 Remington.

Are you sure the headstamp didn't say .222 Rem Mag or some such?

The .222 Rem case is shorter than .223; the .222 Rem Mag is 2mm longer and could have been resized and trimmed to .223 specs.

BTW, M193 would not have the caliber marked, would it?

FWIW, the .218 Bee, .219 Zipper, .220 Swift, .221 Fireball, .222 Rem, .223 Rem,, .224 Weatherby Mag, and .225 Winchester all use the same diameter bullet - .224. The name of the cartridge has only a casual relationship to it's actual design specs.

i was going to do a build in the .222 remiungton, because i like the not so average caertridges, but after looking at it... it was no better then the .223. harder to find, and no real advantage. it is though a very accurate round.

The 222rem is my FAVORITE Hi Power 22

My 222rem bolt action was a true tack driver
and the most accurate Rifle I ever shot in my 40+ years

Don't forget the .22-250!

A friend has a Rem 700 in .222, and it is a very accurate round.

In my country civilians can't use .223, we use .222.

Is that a cnc'd upper? Got more pics?

What are the gun laws like in Spain?

Yes, it's CNC'd.

About our gun laws, in few words, we can only have weapons for sport shooting or hunting with a lot of restrictions. And we can only have as much as 10 pistols and only for sport shooting with even more restrictions.

Positive, the head stam says .222 REM. Then on the opposite side it says RP with a dot in the middle. I tried taking a pic but it was tough, you might be able to make it out.

The M193 only says LC 04 across the bottom (Lake City 2004?) with the NATO stamp at the top, again, blurry pic but you can kinda make it out.

You can se the difference when they're together. Here's also a pic of it on the stripper clip, hence how it was so obvious.

That might not actually be M193, not exactly too familiar with military ammo, but that's what I figured it to be.

from the pics looks like a .222 rem casing found its way into the loading press with all the other 5.56 casings. Tha cannular is visable on the .222 rem and appears to be loaded to the same OAL as the rest of the ammo, as anyone that reloads knows that aint right.....

Reloads.

Overall length of the .222 round makes it seem obvious that the same seating die was used for the .223/5.56 rounds.

Progressive press?

I would definatley guess all reloads, no case discoloration on neck as is familiar with M193. I hope you got this ammo from someone you really trust, as I do not think any of it is M193.

There are dozens of others, I'm sure. My point was that despite the number in the name of the cartridge, the bullet diameter is the same.

The round shown is indeed a .222 Rem. Had you fired it, bad things would probably have happened. Don't get any ammo from that guy any more.

I have ANNEALED M193/m855 that was polished

Most all brass is annealed

some are put in a case cleaner afterwards then loaded

Firing the .222 in a 5.56mm would likely have the following chain of events:

- The extractor would hold the case far enough back that the firing pin could detonate the primer.
- Pressure forcing the bullet forward would also force the case back tight agains the bolt face.
- The brass would expand under pressure and form the .222 case to the chamber walls, but it would not be long enough and would have little or no neck
- The gun would probably have cycled, ejecting the brass and you would probably never have noticed, unless you pick up your brass afterwards.

Many gun stores that have been around a while have good collections of mishaps like firing 8mm Mauser in a .30-06. It rarely does as much damage as people imagine. Guns are designed to be a lot more tolerant of mistakes than people give them credit for, and the hazards of excessive headspace in many people's minds is exaggerated beyond all reason.

Honestly i would pull some of those rounds down and check them to be sure they are correct, some of those rounds look weird to me.
