Keith, That is an outstanding range facility, blending in with the trees and protected from the wind! I forgot to mention in my post that most of my shooting is from inside my office!~ It is air conditioned in the hot and humid summers and heated in the winter. I keep my whole house thermostat set at 70 degrees. My pellets travel about one to two feet before exiting through the office window. My set up allows me to practice on targets out to 44 yards and take down unwanted birds in the trees to a distance of 61 measured yards. My recently added to back stop now measures 9-1/2" deep, constructed of recycled fencing and 4 X 4s. Since you mentioned your location, I was wondering if you have a fire ant problem?
