You briefly mentioned "wear" on the weapons in general when using different ammunition types. I'm a small arms repairer in the Army. We've been using the M855A1 for a while, and we (collectively, the repairers) have seen increased wear that we've contributed to the ammunition. The army had to make a new standard for barrel erosion because of it. Not to mention damage to the feed ramps from the rounds not being presented at the normal angle of the M855 out of legacy magazines. We've also noticed that the bolt rings seem to wear faster now. Ive been trying to see if there is noticeable wear being caused to M4s in other places because of the ammunition. I haven't noticed anything else, but M855A1 is a pretty spicy round, so i imagine its only a matter of time.

Small Arms Solutions has an article on M855A1 EPR vs M855. "Looking at chamber pressure, both cartridges were fired in a 14.5 inch M4A1, both projectiles are a 62 grain projectile. The M855 has an average chamber pressure of 51,522 psi, which is within the 52-55,000 psi range the M4 and all 5.56mm military rifles are designed. The M855A1 is increased vastly to 61,830. In fact, you see pressure levels as high as 62,900 psi. Please keep in mind that a proof cartridge is 70,000 psi. Clearly the rifle is being significantly driven past its design parameters. The increase in chamber pressure also increases the bolt velocity substantially driving the cyclic rate much faster, which increases parts wear and service life of both the bolt and barrel."

I think that's what we're seeing industry wide in a lot of .223/.223W/5.56 chambers is a huge variances on tolerances. Many ammo manufacturers since 2017 have dialed pressures back 10% because of complaints of popped primers or ammo issues. This has is very apparent on M193 variants.

I think lucky gunner did a test with different barrels and some of the. 223rem showed lower pressure than the .556 barrels with the same rounds.

Caleb is a breath of fresh air. Clean cut, articulate and knowledgeable. This is one of the best videos I've seen on the subject. Just last week, shooting an older CAR-15, had fired several magazines without issue. When I got to the mag's with M-855 in them, the rifle started throwing a huge muzzle flash with twice as much recoil. Actually jammed the gun a couple times. The rifle has a .223 chamber but has had thousands of rounds of M-193 5.56 ammo thru it. It definitely didn't like the 855 stuff. Probably won't be shooting M-855 thru that rifle anymore. Listen to Caleb people.

I appreciate when an organization can update past misunderstandings. This is a learning process, and info is vital to safety and longevity, both to human life and the firearm. Handloaders have all this to overcome, apply and disseminate to make a quality product that may be passed to the next generation. Case capacity affecting pressures and velocities, chamber and brass resizing dimensions vary according to application, powder and bullet lots can be inconsistent. The more we know about the effects and outcomes of variables, the better we become.

One nuance to keep in mind is import restrictions. I've heard that Saiga rifles were imported with .223 Remington marked on the receiver while being actually chambered in 5.56x45 NATO because they would be considered a sporting guns rather than military ones. I don't believe the barrels are marked with any chambering.

I have a Ruger Mini-14 Ranch Rifle from '99 and although their are no barrel markings for the caliber, it is marked on the receiver CAL. .223 not .223 Remington. The manual states that either .223 (5.56mm) or standard US military ammo can be used. Ruger also confirmed that all Mini14's with the exception of the Mini-14 target model, have 5.56mm chambers, so either .223 sporting ammo or 5.56 NATO ammunition can be safely fired.

They have. The pressures vary depending on the chambering. (See ballistictools article on this.) The presumed reason for this is the length of the leade in the chamber specification and specification for the cartridge length (and probably specified powders). However, for the specific loading the pressure testing is part of specification. So, NATO spec has a pressure test standard and SAAMI spec has a pressure test standard.

Luckily the friend shooting the rifle was not injured, but the rifle was destroyed.

Synopsis: Use the ammo for which your firearm is chambered.

Colt introduced confusion to the topic 30 years ago. Sitting on my lap is an AR, and the lower markings state, " Colt SPORTER MATCH HBAR CAL. 223." The barrel is marked, " C MP 5.56 NATO 1/7 HBAR.". I like to consider this rifle as the first ever, 223 Wylde.

Great video, excellent info! I received some bulk reload 5.56 NATO ammo, which may have been loaded hot. I don't have chrono data, but will relate my experiences using those rounds in three firearms. (Be sure to scroll down to the Mini 14 info.) Rock River Arms (Advanced Tactical Hunter model) 5.56 Wylde chamber purchased in 2017: Nothing unusual to report. Colt AR-15 HBAR (round handguard, open sights), chamber marked .223, purchased from original owner in 1995: Buffer seemed to travel to max rearward position, and could hear a ringing sound (I think from buffer spring) through hearing protection after each shot. Factory .223 rounds did not do this. Ruger Mini-14 Ranch rifle, stainless steel, purchased new in late 1980's: Significantly more perceived recoil from these rounds than factory .223 rounds. The brass was ejected even more vigorously than normal. I stepped off the distance where the brass ended up in mowed lawn and estimate 27 yards travel! The firearm did not appear to be damaged in any way, but I never shot that ammo out of that firearm again.

Keep up the good work!

I saw a different video discussing the differences between 5.56 and .223 and they also said the pressures of these rounds were different mainly due to the differences in the ways they measured between the NATO method and the civilian method. They did say that when they used the civilian method of pressure testing ammo on the 5.56 ammo, they got very similar pressure values. They went on to say that the pressure differences is mainly due where each method measures the pressure at with in the chamber. This is not to say that all 5.56 rounds can be fired in a .223 rifle, since some of the heavier/ longer 5.56 rounds may be too long for the .223 chamber. This later instance could cause a high pressure problem in a .223 chambered rifle.

If you have any doubts go with vanilla 223 commercial ammo. I have a 5.56 chamber gauge and throat reamer. My SP-1 1974 production passed. The AR-180 had one tiny burr in the throat. Two brand new 5.56 DPMS barrels both had serious throat burrs that took a few turns of the reamer to get a go with the gauge. I have fired 5.56 in the SP-1 and it is weaker than some of my varmint loads. If you are reloading, go by the most recent published reloading date for your components. Family pay for hunting trip business was ammo reloading until the Mid 70's,

Thus, the ammo that we can buy here is ALWAYS CIP approved, we also can't get the M855 (Green Tips) Some of our .223 REM labled ammos, like Geco, PPU, IMI and what not, are sold in the US as 5.56 NATO, as they are outside of the SAAMI spec. The only real NATO ammo that you can buy in Germany is rebrandet and CIP TESTED, SM ammo comes to mind here. That said, individual firearms an ofcourse have issues with individual types of ammo. For exsample, when my Schmeisser Ultramatch was relatively new, I could not safely fire 77gr .223rem from S&B. Also, I had a test pack of SM rebranded Santa Barbara 5.56 NATO 55gr, which had an issue in my 16" upper, but tha issue was easily resolved by either reducing the gasport or insatlling a heavier buffer.
