When it comes to .223 Rem. semi-automatic rifles, Ruger’s Mini-14 has long been one of the obvious choices.

It is actually chambered in 5.56 ...

LOL! Yeah, it’s one of those “Is it safe to shoot .223 in it or only 5.56 cause it explode in my face” deals. The mini is way tough enough. I seem to remember a thread quite a while ago about chamber pressures for both but don’t recall the details. If I remember correctly the .223 has higher pressures. I’m sure someone will educate me/us once again. So, thanks in advance :>)

“It is actually chambered in 5.56 .”

Then Ruger made a mistake on Mrs. L’s Stainless Ranch.

No, its NOT.

Its chambered for .223. Ruger will tell you so. You can go ahead use 5.56, but you are going to find accuracy falls off due to the higher pressure. Call Ruger if you don’t believe me, they will strongly recommend you not use the military round.

The weapon was designed to digest .223 and its very accurate with that round.
