Year's ago I was getting into black powder shooting competition. I cut this paneling to match various and readily available target sizes and frame's I built. I did this so I could recapture my lead and recast it. I got busy with other things yadda yadda. Prices start at $20 and go up to $100. A full sheet of this stuff will cost you close to 700 and then you have to cut it which ain't easy. A friend shot one of these with a 30.06 and it just made a bulge. Rated up to.44 MAGNUM.
