Best homemade backstops....

[rasp65]

Gene About 20 years ago my cousin built a nice range. He used a tractor with a front bucket and scraped and dumped the dirt intoa 15 ft berm about 10 ft high. Eventually grass grew over it and negated the effects of erosion. We will eventually be improving our 200 yd berm and will use the method outlined by Bill above. We are planning 3 layers of tires filled with sand about 6 ft high. Another option is to have a load of dirt dropped in 1 pile and you have instant backstop. Erosion will be a problem until something grows on it but you probably won't loose too much by then. Be careful about having too much rock on the outside as it could cause ricochets.
