No. Do not shoot 5.56mm ammunition in a rifle with a.223 Remington chamber or you are risking a potentially dangerous incident. So, while it's safe to shoot.223 Remington ammunition in a 5.56x45mm chamber, the reverse is not true. If you fire 5.56mm ammo in a.223 chamber, you could potentially experience serious trouble from a pressure spike Some professional shooters claim that firing.223 ammunition through a 5.56 Mil-Spec chamber results in less accuracy, though this should be nominal. Additionally, it is extremely safe to do so, which is the most important part IMO a 5.56 chamber and 1 in 9 twist would be the best option for that sort of rifle. It will have no trouble with 55-69gr bullets, and you should still be able to achieve MOA (or close to it) with handloads, but without compromising reliability or the ability to shoot cheap bulk M193 accurately (for instance, my SL8 with 1 in 7 twist cannot. I've read alot on firing 5.56 ammo in rifles chambered for the .223 Remington (bolt action) which is a no-no, but its OK to shoot .223 ammo in a 5.56mm chamber. Read and understand the dimension's and all concerned this and that.. My 5.56mm shooting/reloading over the last 28 some years has been in a Ruger Mini-14 and several AR15 types
In summary: .223 Remington ammunition may be shot safely in either a .223 Remington or a 5.56mm chamber. However, you should only shoot 5.56mm ammunition in a rifle with a 5.56mm chamber or you. The only differences between 5.56 and.223 are in the chamber, with the bullets and barrels being the same, though the chamber differences do result in an general accuracy disadvantage for 5.56 due to what could be considered excessive free bore in the design (this may have been put into the design to accommodate certain types of special purpose military ammunition) .223 and 5.56 Ammo So the supreme benefit of 5.56 chambers is that you can shoot.223 ammo and 5.56 out of a 5.56 chamber without reliability or safety concerns. That gives you the flexibility to take advantage of the great military surplus ammo bargains when they are available It turns out that Ruger uses the same approach that Wylde chamber was designed to, it's reamed with a lead that's longer than the .223 but shorter than 5.56/NATO. That allows it to safely shoot the higher pressure 5.56/NATO rd while retaining most of the accuracy of the tighter .223 chamber
What are the best.223 Wylde rifles? In the AR-15 world, it is a little known fact that.223 Remington and 5.56 NATO vary just a tiny bit when it comes to pressure and chamber dimensions- and the.223 Wylde chambering was designed to pull off the magic trick of walking the tightrope between the two, and doing it accurately I had hoped to get a .223 Wylde upper because I want to get a lot of practice with bench shooting. I'm just a little bit concerned about the Compass Lake specification chamber in the above link. I hear that the dimensions of the chamber are best suited for .223 bullets and that only some 5.56 rounds would not cause a pressure problem The morefirmly freebore size in a 223 Wylde rifle grants you to shoot.223 ammo with by and large strong accuracy from it than a 5.56×45 rifle. To truly acknowledge what 223 Wylde brings to the table, you have to comprehend 223 Remington and 5.56×45 as gauges. It is a top choice for competition shooters: American Eagle XM193 55 g
For instance, when using hot 5.56 NATO rounds in a .223 Rem-marked rifle with a tighter chamber than what the military round was designed for, pressures can push into the 70,000 psi area in worse case scenarios since the mil-spec round doesn't have the extra length to expand into, which isn't good, especially in long term use I'm ordering a new barrel for a bolt rifle. I was planning on using primarily 68-70 grain bullets. The barrel maker says that I should get a 5.56 NATO Match chamber, not a .223. They say I can use my .223 Go and No Go gauges (this is for a Savage that I will be switching barrels on) and of course my .223 brass When shooting .223 Rem. cartridges in a firearm chambered for 5.56x45 mm, it's likely that there will be a degradation in accuracy and muzzle velocity due to the more generous chamber dimensions
Practically speaking, most factory 223 bolt action rifles come with longer than SAAMI throats, which would alleviate concerns running higher pressure 5.56 loads in a 223 chamber. Also practically speaking, many handloaders run their loads at pressures equal to, if not in excess of, 5.56 with absolutely zero ill effects Instead, ONLY chamber 5.56 NATO in a 5.56 chamber and a .223 ammo in a .223 chamber. However, you can safely chamber a .223 ammo in a 5.56 chamber. That's because the 5.56 chamber can fit and withstand the .223 ammo. In comparison, the .223 chamber can only fit the 5.56 chamber but not withstand its pressure. That's wh Thus, it is ok to fire .223 rem rounds from the 5.56 chamber but it is not ok to fire 5.56mm rounds thru .223 Remington chamber. It will simply cause pressure problems. To avoid this issue, Bill Wylde (and hence the name, .223 Wylde), had an idea to create a chamber that would clear both rounds, 5.56 NATO and .223 Remington Lately PSA has been offering .223 Wylde chambered barrels at a good price. I have heard it stated that you should not fire 5.56 in a .223 chamber. I have also heard that the .223 Wylde chamber can offer increased accuracy, which apparently is debatable. So my main question is, can you safely shoot 5.56 out of a .223 Wydle with no high pressure.
. Dec 3, 2016. #9. Both the .223 and 5.56 are loaded to the same chamber pressure of 55,000 psi, the problem is the 5.56 throat is twice as long as the .223. Meaning when you shoot M855 military ammo in a .223 with a shorter throat the chamber pressure will be approximately 60,000 psi Using commercial .223 cartridges in a 5.56-chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223-chambered gun due to the excessive leade.  Using 5.56 mil-spec cartridges (such as the M855) in a .223-chambered rifle can lead to excessive wear and stress on the rifle and even be unsafe, and the. .223 Remington vs. 5.56×45-Chambering and Throat Considerations. Should you be worried about shooting 5.56×45 milspec ammo in a .223 Remington? The answer really depends on your chamber. 5.56 x45 ammo is intended for chambers with longer throats. If you shoot hot 5.56×45 ammo in short-throated SAAMI-spec chambers you can encounter pressure.

What these hybrid chambers claim to do is offer the interoperability of the 5.56 NATO chamber with accuracy closer to that of the 223 Remington chamber 5.56 Nato Chamber - You can shoot both .223 & 5.56.223 Remington Chamber - You can only shoot .223, nothing else - IF You Believe The Nay Sayers.223 Wylde - You can shoot both as well, the only difference is it's more accurate because it's a hybrid barrel
.223 Wylde chamber is a hybrid rifle chamber designed to allow .22 caliber barrels to safely fire both .223 Remington and 5.56×45mm NATO ammunition. While the cartridge dimensions of both rounds are the same, 5.56 NATO loads produce pressures in excess of the .223 safe spec. The 5.56 chamber has angular differences that allow higher pressures safely The only time I've had issues with 5.56 loads in a true .223 chamber was with full tilt max 5.56 pressure handloads in a .223 chambered AR. I had to back those off a bit, but most 5.56 factory loads are not full pressure loads. In all but the rarest instances, this whole conversation is a big todo about nothing Freebore is the space between a rifle's heap and the rifling in the barrel. The morefirmly freebore size in a 223 Wylde rifle grants you to shoot .223 ammo with by and large strong accuracy from it than a 5.56×45 rifle.
