Benjammin,

Ruger's original intent was to make the Mini-14 in .308. I remember in the 80's when they were floating the idea. If I remember correctly they had some sort of issues with the action and the .308 cartridge. That is why they went with the 7x39. Less OOOMPH I guess.

My two cents and foggy memory.
