Check out my most recent project that I finished up with the Kioti NX6010. This was just a few days ago, March 10, 2018, the ground was barely firm enough to work, but I had to do it!
/ Long Range Shooting backstop with the Kioti NX6010 Awesome project!
Very nice video and range. The only thing I would do different is to now top your 3 inch with some 0-3/4 so that if you want to shoot an auto pistol while standing on the gravel, you will have a far easier time picking up your brass. The 0-3/4 will pack down almost like concrete.
