The Ruger Mini-14 Ranch Rifle marked as .223 can safely fire the .223 AND the 5.56 NATO military cartridge. The Ruger Mini-14 TARGET model should only fire .223 ammo- no 5.56 mm

If you are referring to a Sturm & Ruger Co. Mini-14, then the answer is that most were manufactured in .223 Remington. The Ruger factory has from time to time released the Mini-14 rifle in .222 Remington in limited numbers, most likely to satisfy limited markets (some countries do not allow sales of "military" calibers.)
Best left to a trained factory representative.
most minis are .223 caliber aka 5.6 NATO <><><><><> Although similar, the .223 Remington and the 5.56x45 are NOT the same cartridge. A rifle chambered for 5.56 can shoot .223 safely. The reverse is not true- a rifle chambered for .223 MAY be unsafe with 5.56 ammo- it has a slightly longer cartridge case, and is loaded to higher pressures. Safe bet is to check the caliber marked on the firearm, and stick with that.
