With slugs 30-40 feet. The buck was with 6 does, and I couldn't get a clear shot till they were all that close. Believe me it's not easy to move and aim with 7 sets of eyes looking around that close. Farthest with a shotgun period was this guyhttp://i27.photobucket.com/albums/c198/Fanofde4ever/Picture.jpg at65 yards with my 870 Express and #1 buckshot.
