I don't know of anything in Minot. We shoot high power and F-class in Grand Forks, which is 3 hrs away. F class is on Sunday afternoons once it warms up. We fire from 300 and 600 yds.
They also do some long range shooting in Bismarck, which is alot closer for you. I do believe they shoot out to 1,000yards at their range. Rolla, which is probably 2 hours from you also hosts some matches over the course of the summer. Travis.
