I'm originally from Butler Co. I have 4 brothers still there. Ever hear of Chip's kennels.?
Long shots on chucks were on one farm only. Maybe 300 yds plus. In those days Dad shot'em with open sights.
Look for a pipe line or power rightofway. You'll probably never see anything
but dreamin' if half of it any way.
I'm having a rifle built, should be here any day, specifically disigned for yotes beyond 600 yds. They are shot at by so many that they can be called in to about 600 at several places. The rifle will be sufficient for deer also.
