Don't use Home Depot foam products! Especially if yo have an acreage. Trust me, I've been through it all before. I have a construction company and have used several different types of building materials to shoot targets with. Sure SOME work, but none last, then it's back to the drawing board.
I once made one out of a tire and several layers of soft board and spray foam, cost me about $80 in material, only lasted a couple months. The best home made target I have ever made was when I cut a bunch of 6" strips of soft board (felt board) 4' long then stacked them 4' high, ran a ready rod through each side and bolted a 2x8 top and bottom. That target lasted a long time, but it wasn't cheap and took a long time to build.
Just go buy one of those bags for $60-$80 and shoot the heck out of it, then once its shot out all you need to do is buy a replacement cover for $20. That's about the best advise I can give you.
