    Can you shoot a 5.56 round through a ruger mini 14? A friend said no, but was unable to explain why not.

    The Ruger Mini 14 is now, and has been since it was first manufactured, chambered in 5.56. If you go to ruger.com, you can download an owner's manual for your gun. Under "ammunition" it says that the gun is safe to fire with any 5.56 or 223 ammo.

    So, yes. You can shoot 5.56 in a Mini 14.

    I have fired hundreds of 5.56 through my Ruger Mini-14.

    Question is can you fire the slightly less powerful and slightly different .223 through it?

    The latter I do not now. All I ever fired through mine is military surplus 5.56.

    Interested parties might want to follow and read the following and associated links that seem to be reasonably accurate:
    http://en.wikipedia.org/wiki/.223_Remington#.223_Remington_versus_5.56_mm_NATO

    This question of 5.56 NATO ammo safety in non NATO dimensioned (e.g. commercial) chambers is a complex one. The NATO chamber and barrel throat is designed to let the bullet get moving easier than most commercial (sporting) chambers.

    For possible liability reasons, I will not advise shooting any NATO spec 5.56 mm ammo in a non NATO spec commercial chamber; but I will advise one NOT to shoot any NATO spec 5.56 mm ammo that has a bullet heavier than 55 grains (e.g. M855 or SS109) in a firearm that is not specifically chambered and certified by its maker to be suitable for NATO spec ammo.

    Here is another seemingly reasonably accurate technical link for anyone interested:
    http://en.wikipedia.org/wiki/.223_Remington#.223_Remington_versus_5.56_mm_NATO

    Hope that the foregoing is useful.

    Yes as Alpo has explained, the Ruger Owner's Manual says it is good with the use 5.56mm ammo. Despite saying .223 Rem., the Ruger Mini-14 has always had a 5.56 chamber.

    The only exception is the "Target" model, it must use .223 Rem. only.

    Ruger Owner's Manuals are available online to anyone who wants one for their specific model. The information regarding the proper ammo to be used is listed under "Ammunition"

    I will throw in an additional comment about civilian packaged 5.56 x 45 mm, M193 ball ammo made and packaged (or imported) by major U S based ammo companies like ATK (Federal) at the LCAAP. It usually has an "X" somewhere in its designation. For example: "XM193F" for Federal M193 Ball.

    Such ammo is loaded to SAAMI pressures at the case mouth. See this link: http://www.federalpremium.com/resources/xm193.aspx

    Still manufacturers cover their "Donkeys" with warnings that go with the SAAMI advice directive not to shoot in sporting chambers and barrels.

    Things are what they are.

    And I just confused the nice lady at Ruger.

    "I know that I can shoot 5.56 in my .223-marked Mini", and she says, "Yes, you can", and I finish, "but can I shoot 5.56 in my .223-marked #1? Or is that strictly commercial ammo?"

    She says, "Wow. Never been asked that one before. Let me go check".

    In case anyone else is interested, the answer is "no". It's .223 Remington. The #1 does not come with a 5.56 chamber.

    Single shot falling block, based on the Farquharson action.

    I got two. One's a 45/70 and the other's a .223.

    Relative to Alpo's posts #'s 8 & 10:

    http://www.ruger.com/products/no1Varminter/models.html

    I wonder why Ruger puts a 1 in 9" twist barrel on the .223 Rem. rifle, while leaving the .22-250 Rem. at 1 in 14"; if they do not expect that it is going to be shot with a lot of M193 and M855 NATO ammo.

    One turn in 14" only marginally stabilizes a 55 grain boat-tail bullet, at 0.13; which means it will start to tumble under standard barometric conditions at temperatures much below 50 degrees F. Of course, 50 grain flat base is usually the preferred groundhog bullet for the .22-250; and 1 in 14" works just fine. One turn in nine it typically what is needed to stabilize 62 grain plus, 0.224", BT bullets, typically found in military loadings.

    Also the velocity produced by the .22-250 is some 400 fps faster than the .223, thereby requiring less twist to get the needed RPM to stabilize the bullet.

    For example. A .223 9 twist will not stabilize a .224" Barnes 70 gr TSX, but a .22-250 9 twist will.

    Make sense?

    JLA in post #13 not only "makes sense", but I am confident that all statements made are in fact accurate.

    accurate as a properly stabilized bullet.
