You have property at home you can shoot on. I don't even have a place to practice past 10yds flat, let alone inclines or declines. The nearest gun range that will let me shoot off the ground instead of a bench is a 90 mile drive to Diablo.
I have some new ideas for next year but our steepest target this time was measured with an incline meter at 25-27 degrees.
