Sorry I can't help you out. I made my own at my house. Build up a 3ish foot tall, 4 foot think berm out of dirt when we had a Backhoe here. Perfect for plinking or Pistol. I have 10 acres of land on my side plus 400+ acres of family land on the other side of the road. My neighbor is a avid shooter and doesn't mind the sound, and my other neighbor, a cop, has never complained. So I guess I got it pretty good. How about Bath Rifle & Pistol Club in Woolwich?
