    223, l21a1

    Just looking for some info please,

    Can you fire a NATO L21A1 round through a 223 rifle? Eg, browning x bolt?

    Showing on the case are, L21A1 08 T it has a circle with a cross in it as well

    Cheers

    Your not supposed to mate as the max pressure ratings for 5.56 and 223 are significantly different. However if your rifle is chambered 223 wylde the n fill ya boots

    I doubt any factory rifles come in that chambering. Unless its an AR or a custom build it will be either 5.56 or 223 chambered.

    That means its only proofed for the 223 sammi spec loads. 5.56 is significantly higher pressure. Some people use 5.56 in a 223 but I don't see the point.

    What are you wanting to use the ammo for?

    I use it mainly for foxes, had chance of some L21A1 rounds at a very good price

    Mate I wouldn't use fmj rounds on fox!!!! You'll have ricochets all over the county! Stick with stuff designed for the purpose like vmax etc

    what he said, if you google this you will find a variance of opinion..some wil say yer okey probably and some wil say doom gloom boom you will die.
    truth is somewhere in between

    5.56mm is not .223rem

    the bullet weight will be likely heavier in 5.56mm if its milsurp and the COL maybe longer so more likely to have a heavier bullet jamming into the lands with a higher charge than the gun is proofed for, depends how your chamber is cut and throated etc etc...it might work..it might be fine
    but
    deffo not recommended
    e.g a Steyr Aug maybe proofed .223rem but have a 5.56mm chamber cut so be fine with milsurp. same for AR variants.

    easy answer is dont do it...cheap ammo vs the chance of damagin your gun or worse
    Gun control means using both hands.

    The Cornish don't worry about things like this in my experience

    Should you fire it through a .223 Rem?? well, I would give it a miss if your rifle is a standard .223 Rem. (on the other hand if it was M193 ammo then that's another kettle of fish, I would be quite happy using that in a .223)

    It's not M193 so don't worry.

    This is Ruag ammo made for the military and has the T for training, as it wasn't passed for use 'in theatre', I think because of some packaging issues and not due to the ammo itself.

    This is to all other intents and purposes the same as standard military fodder, eg SS109 with the 62gn bullet.
    It is rather good for target use (certainly one of the best of the surplus lots out there) but not really suitable for use on foxes and the like.

    BTW M193 has the 55gn bullet.
    Good deals with: Muskett, Dreben, roger.kerry, TALL, Helidave1, Chelseablue, Leeroy7031, Mousemann, pnuk, Practical, NEWFI, HOOGS, Webb22, lazybones1416 and deanw5262 among others. Thanks Guys.
