And if I have my facts right. The reason the mini 30 in 7.62 x 39 is not the most accurate rifle is that the bbl that is used in the mini 30 was actualy set up for the XGI. Ruger shelved the XGI due to chamber pressure problems. But when the 7.62 x 39 round became popular, they pulled it back out. They save some $ on R & D and used the numbers form the 308 round for the mini 30.
