Here's my favorite spot. It's a large rock quarry and you can squeeze 100yds out of it if you try. Plenty of room and not over populated like Brown's Camp is. Turn off Hwy26 just after Sunset Rest Area (1/2hr west of North plains OR.) here's the GPS/Satellite link:

Let me know if you want company or a guide. I'm more of a social shooter lately
What's wrong with shooting in the cleared areas along Sterling Ranch Road? Isn't that all BLM land?
