Member Link Up In the Blackhills June 8-15 looking for a spot to shoot.

[TroyMN]

Hello I am going to the Blackhills with the family next week. June 8-15. Wanted to bring the 308 if I could find an area or person to shoot with in the 400-800yard range.
Any public ranges? Anyone buy Jellystone Park that likes to throw lead out a long way at paper and steel?
Thanks
Troy
