re: backstop:
esshup, I got the pier posts from a demo job I did at the lake. That's the back layer holding back the berm. When we bought the new place, it had the big loading dock timbers on it. I had enough so that I could double up the material in the bullet catching zone. I had used plywood the way you describe on my last one...worked pretty good.
Dave, no doubt the backstop is huge for experienced shooters, but we have a lot of friends/family that are just getting into shooting. That's why I built it so big.
Y'all have a great day!
