CONFUSED! .223 Wylde

[FJoel]

The problem is not with the Wylde chamber as it's designed to fire both 223/5.56. There is an issue firing 5.56 in a 223 chamber confirmed by Saami! Enough said.

*potential issue...

Thus, while .223 Remington ammunition can be safely fired in a 5.56 mm chambered gun, firing 5.56 mm ammunition in a .223 Remington chamber may produce pressures in excess of even the 5.56 mm specifications due to the shorter throat.

Not HAVE OR WILL, but MAY.

I may get struck by lightning next time I'm hunting too.

The lead in solder may produce harmful reproductive side effects as well, but I still replaced the speaker in a CB radio last week.

i agree with you, the 5.56 is safe to shoot in any rifle chambered in 223. i have shot hundreds of 5.56 in my weatherby vanguard and is way more accurate then the standard 223 ball ammo.

Same here, I have fired many rounds of both calibers in both chamberings, I have never had a problem with it.

The gun plumbers at my unit have never physically seen or even heard of a documented (read non internet based) problem caused by it (all the ones I have spoken to on the matter) some of them have been techs for 20 plus years have even retired and are now civilians still doing the job.

The confusion seems to stem from different measuring systems in the European and SAAMI sphere of numbers, math, angles, sub atomic scale measurements in non-metric and metric.

who cares.

I've done it, thousands of others have done it and have been doing it all over the world for a long long time and noones #### seems to have fallen off in any documented fact based incident ever.

I'll be the first one on here admitting I was wrong and offering documented proof that my rifle exploded, complete with pictures and a gun smiths written analysis of the cause if anything ever goes wrong. Don't hold your breaths though

Much ado about nothing.

I think another gentleman on here said it best when he said: "There never was an issue with it before the internet came along"

Too true man, too true....

I am stating facts. Hundreds of thousands of rounds without one incident of a rifle blowing up. Maybe they were just lucky

Hearsay unless you personally checked every gun used for what chamber it had. rolleyes. Listen people are not saying you will blow your gun up right away if you shoot a 5.56 in a 223 gun. It's obvious that won't happen, but we are saying you will cause exccessive wear and the problems that go along with that, like premature parts breakage and possible catastrophic failure of some sort. You are comfortable risking it, some not. By the way I do consider people who do it excessively "lucky".

I guess that makes me an ongoing experiment in incredbile luck then eh?

Like I said, the day I have a failure of any kind and I can find a gunsmith willing to judge that it was due to excessive pressure/wear/explosion caused from mixing ammo in these chambers I will post it to this site ASAP complete with pictures and an apology.

Time will tell I suppose.

Yeah maybe! Better you than me.

The original SAAMI 223 chamber had a short throat well-suited to the 55 gr bullet in 223 and 5.56 ammo. Shooting that ammo was not a problem, and is much less a problem now.

BUT, the 5.56 tracer round is much longer than a 55 gr ball bullet. If the tracer was fired in a short SAAMI chamber the bullet could be engaging the rifling while the tail of the bullet was still below the case shoulder, risking a rivet effect, spiking pressures.

Two things to bear in mind: SAAMI specifies how short the throat can be, but does not specify how deep the throat can be. You may have noticed that Remingtons have much longer throats than Winchesters in all calibers. When working on the Savage 1:9 project, I suggested Savage use the Wylde chamber (a long gentle throat that accommodates any bullet). For the prototypes, I used a throating reamer to convert the standard SAAMI chamber to a Wylde.

Savage, in their wisdom, decided it would be simpler to use the SAAMI chamber for the chamber and the NATO 5.56 drawing for the throat, and this is what they did.
Second thing to remember is that manufacturers today are not using the short SAAMI chamber. Other manufacturers have also used throats longer than the shortest possible permitted by SAAMI.

Manufacturers are very leery of litigation. I cannot imagine that any of them use a chamber design today that is incompatible with 5.56 ammo (ball ammo). But I would not trust 223 chambers to shoot tracer.
