CSA M4 non-restricted VZ-58

Fix yourself!

.223 and 5.56 are the EXACT same. Just as .308 and 7.62. Any AMMO tech in the military can confirm this.


Wow, this is blatant misinformation, ####ing edit your post and correct yourself before someone believes you.

It's only "close enough" to being the same when you have a 5.56mm chambered weapon. Not when you have a .223 chamber.
 
My understanding and rule of thumb is if the rifle is spec'd and the manufacture confirms it is chambered for 5.56mmNATO then you can also use .223 Rem. NOT the other way around.
BUT for Ex: I owned the latest MINI 14 Ranch rifle and it was stamped .223 Rem. I called RUGER to confirm if it can shoot 5.56mmNATO as their website specs indicated. They confirmed to me YES its chambered for 5.56mm and stamped .223 Rem because of export rules etc...NOW the MINI 14 TARGET version is strictly .223 Rem and they confirmed do not shoot 5.56mm in that rifle.

Ranch Rifle:Caliber: 5.56mm NATO/.223 Rem

Target Version:Caliber: .223 Rem

Also my XCR is stamped .223 Rem but RA and its Website, just like RUGER confirms its chambered for 5.56mmNATO
So IMO its best to confirm with the gun manufacture and make sure you are asking about the exact model you own.
 
I know that this thread is not actually about the differences in 5.56 and .223, but I've seen this debate before and its hard to watch without getting involved.
I have found bigger variances in ammo between different manufacturers of the same caliber, than I have found between .223 and 5.56. I've even gone so far as to get out the digital calipers and check, and I'll try and post some pics later.
I know that this debate will continue long past this, but I hope this will at least show that not all ammo, regardless of whether its .223 or 5.56, is not always exactly the same and that the differences are so miniscule that it really makes no difference at all. I've been interchanging it for years and will continue to do so, and whether other people choose to or not makes absolutely no difference to me. Right or wrong, you will always be able to find a document that will support your theory for either case, but sometimes getting out the tools and doing your own investigation is the best way.
 
kidding right? please tell me you are. I need to believe in something after this mess of thread.

Pretty sure he's joking.

Funny story though... I once went into the Bass Pro Shops in Vaughan, ON and was looking for 7.62 x 39. One of the staff told me "We don't stock that military stuff, but you should be able to use .308 in it, it's the same diameter." f:P:
 
I have had a number of people over the years tell me that you can fire 7.62x39 out of a 7.62x51 fire arm. I was even told on a course during work up training for 03-08 by a Sgt that the reason the AK74 was chambered in 5.45x39 is so that they can use our ammo in their guns if they run out.

I hate experts

haha thanks for the laugh. I was pretty sure you were kidding, but wanted to be 100%

I saw a guy sell someone 22-250 rounds instead of .22 rounds while saying "these will hit way harder for you"
