When I first got my bow from my brother, he had stopped at Walmart and picked up a styrofoam target bout 2" thick. It worked fine with the arrows he brought with it 2216(logs). When I went with smaller arrows or carbons, the increase in speed was too much for it and they went right through. I still use this target though(has the replaceable center), what I did was get a better backstop. A roundbale works great for field tips, but with broadheads, it catches a lot of hay when it is pulled out. If you can get to some shipyards, the bumpers that are put over the ships side make great targets(styrofoam). Other than that there are many good targets available on the market, such as the block,etc. Just make sure to research them to get one that you can easily pull your arrows from. And that they are compatable for use with broadheads.

The best of luck in all your hunting endeavors!!!

God Bless,
