To me, my Mini in .300 is a modern version of the M-1 carbine in .30 cal. It's almost as accurate as my .300bo AR at 100 yards.

No supressor, I mostly run supersonic loads but found that although subs don't cycle the action, they also don't partially eject and cause a jam. So I can operate it like a straight pull action and run thru a full mag with no jams.

But no complaints with the 7.62x39 round either. I have ARs in both calibers and overall the .300bo has better accuracy but 7.62x39 has more energy. I'd take either .30 caliber over 5.56 but 5.56 will always be the cheaper and more plentiful round.
You probably know that Ruger set the gas oriface to work with open .300 super and suppressed .300 subs.

And that various gas orifices and an adjustable gas block are available.
