DF - you sure you shot that with a Mini-14, I had one years (like 20) ago that shot patterns (like a shotgun)...
Then again I was a kid and someone probably smoked it and sold it (I bought it cheap)...
Nice group
Not your typical Ranch Rifle...
Send your Mini and a grand or so to these people and it'll shoot like this...
This work was done years ago when their prices were less
