    Have a Mini 14 coming soon. Does anyone know the effects of using 5.56 rounds in this weapon?
    Is it designed to accept the higher chamber pressures without adverse effects?
    Any help is appreciated!!

    All the Mini-14s, except the Target Model are chambered to use both .223 and 5.56 Nato ammo.

    What the hell is the difference between .223 and 5.56x45 NATO anyway?

    there is also a very miniscule dimension difference I've heard. Something like one case being .0001 of an inch longer or some such. Don't know if thats true, and if it is, how it could really make that much of a difference.

    The military rounds are not suitable for hunting. There are some good options in 223 for hunting. Military brass is fine if you roll your own.

    OK- one more time- and pay attention-

    The 5.56 x 45 does have a higher pressure, and a slightly longer longer chamber. It also uses a longer bullet than some of the civilian .223's. This can result in the bullet getting into the lands when chambered. There have been cases reported of a bullet that sticks in the bore when a cartridge is extracted, leaving you with an obstructed bore for next shot.

    Bottom line- it is recommended by people that know a LOT more than I do that you do NOT shoot 5.56 NATO in a rifle chambered for .223 UNLESS THE MAKER OKS IT (like Ruger does in it's literature). There is also another chamber shape called the Wylde that can run both.

    Yes, you CAN shoot .223 in a 5.56 NATO rifle.

    If you feel that it is safe for you to shoot 5.56 in a .223, may I ask you to please move down to the other end of the firing line? Thank you.

    Basically, if it says specifically .223 follow the rule of using only ammo that your gun is specifically chambered for.

    5.56 Doesn't Shoot As Well As .223 Remington Format

    I have a Mini-14 Ranch Rifle, Mod 5801, 1:9 RH twist. This rifle hates to shoot the 5.56 NATO spec rounds. You couldn't cover the groups with your whole hand spread out. However, in the .223 Remington spec, it loves the Winchester Ballistic tip 55gr, Winchester Varmint HV 45gr, Federal Gold Medal 55gr, and Fiocchi 55gr FMJ. Best groups in mine were with Winchester Ballistic 55gr, with a 1 inch group of five shots.
    Of course your experience may differ.

    Enjoy,
