I would buy a proper target designed for high speed arrows. It is worth the investment to save arrows and time sharpening broadheads. When I bought my crossbow over 15 years ago, I also bought a "The Block" target. I have been using it ever since, almost exclusively with broadheads. I have never had a pass through, but the arrows are starting to go in right up to the fetching, so it is about time to replace it. I would think you can find something similar in the $150 range.
