I had a Mini 30 in the late 80's. I could actually hit the broadside of an old bus at 25 yards, but it grouped like I had a cylinder choke installed; it was dumped at the next gun show. My 2-3 Mini 14s from that era performed similarly and they met the same fate.
I can't believe the prices these things currently command -
$750 to $850 in my neck of the woods.
