Knowing there IS a difference, I was wondering how Ruger actually bored that rifle?

Anyone know?

minis are .223 /5.56 so they shoot both

Not necessarily true.. if one purchases a .223 thinking it will handle 5.56 NATO he/she may be in for a nasty surprise for the 5.56 will drive pressures to gun-disabling pressures if the chamber is bored for .223, right? It's a factor of 'free-bore'.. also called 'bullet jump', whatever, but some .223s will fail if 5.56 NATO is fired in them and some BBLS of past issue ARs, even, have been double-marked .223/5.56 while bored for .223.

Perhaps I should just phone Ruger Monday...

It may depend on when the Mini 14 was made. IIRC, the early ones were .223, and sometime later Ruger went to the Wylde chamber, which handles .223 and 5.56. Have the serial number handy and call Ruger. The answer matters.

My Mini-14 was manufactured in 1999 and the manual says both the .223 and 5.56 can be used. The only Mini-14 of which I am aware that can not handle both is the Target Mini which is chambered for only the .223.

I think a call to Ruger Monday is a wise move. The gun I am thinking of picking up is new..

Thanks.

What triggered the discussion and my question was the fact some ranges have experienced broken firearms which were firing NATO 5.56 even though those weapons were labelled .223/5.56.
I know someone makes a gauge which is simply a machined item that one places into the chamber which will tell immediately whether or nor that chamber is 5.56.
