Welcome. I'm in S. MPLS too. I'm a member at,
http://www.frpcmn.com/range/ where we can shoot out to 600 yards. There are other ranges to check out, North Star in Redwing goes to about 600, Elk River goes to 600 (I think), Gopher in Harris goes to 1000. I think there's one near LeSuer that's long range.
Those are the closest long ranges to us, all within 1 hr. drive.
