I have a Mini-30 and I really love it. My little brother has a Mini-14. That's why I call him my little bro!
I think this whole issue boils down to training and shooting discipline. Practice, practice, practice. A well placed shot, even 22 rimfire, is deadly. The old "spray and pray" method just doesn't get it.
I've got a Federal Ordinance M-14S, as well as a Mini-14. They look so cute together!
