I am wanting to set up a target at work. We have a warehouse that will allow me to shot 17 yards. The problem is that the backstop is an adjoining wall to another business. Basic 2x4 drywalled wall. I am trying to figure out what material to use behind my target to keep my arrows from passing through the wall if I miss? (like that would ever happen... :tongue: ) would a couple of layers of 3/4" plywood be sufficient? I am not wanting to invest a ton of money in the backstop, and don't really care if the arrow gets destroyed on a chance miss. Just want to make sure an arrow doesn't pass through the wall. I pull 70lbs and shoot carbon arrows with 100g tips.
