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!! |

See the Ruger website- Ruger® Mini-14® Ranch Rifle Autoloading Rifle Models
Their rifles are listed as using both. __________________

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. __________________
