Admittedly - having private land to enjoy firearms on is not that bad in of itself. I also enjoy sighting in rifles on my dad's farmland, using a hill with no neighbors as a backdrop for a 300 yard target.
I sure wouldn't consider 170 acres very sufficient though. Your range should really have a minimum of 2x your bullet's effective distance behind your expected target just for safety, let alone dissipating the deafening noise. For typical hunting rifles, effective distance can be 500-600 yards. And that means for "hunting" where you won't always be in the optimal location for a safe backdrop, you need 400-500 acres, not 171. That's why most rifle ranges are out in buttfuck nowhere without neighbors, and pistol ranges are inside concrete buildings. Cuz firearm enjoyers who aren't morons or affluenza-afflicted actually care.
