Depends. If you mean the Ruger Mini-14 or Ranch Rifle, yes, you can. It is chambered for .223 and 5.56x45 ammo. If you read the owner's manual (available on the Ruger website) it will tell you that on page 13. The Target Model is ONLY for .223. Of course, the 6.8mm and the Mini-30 use different ammo entirely.
Some studies indicate the repeated use (20,000) of steel cased ammo will prematurely wear the barrel on semi auto rifles. The normal user will not see the difference.
If that is what is printed on your barrel. Most will fire 5.56 x 45. They are not the same.
