Does anyone own a new production Mini 30 in 7.62x39? How does it group with American made ammo from Remington and Federal and Winchester for hunting at 100 yards? Has anyone used the extension from accu -check on the new models? Thinking about getting one for hunting deer for under 150 yards. Was thinking about 223 fro deer hunting under 150 but having second thoughts. Another consideration for me is I don't hand load and don't want to start. Thank you for you replies.
