I don't know what kind of metal brace is along the spine of a Glen Del buck target. But I can tell you it will destroy any broadhead, including titanium, faster than you can say "Wholly S^&*!!"

I like to practice shooting 40 and 50 with my single pin set for 30, just in case. Guess my Experience was shooting faster than I thought as I crushed half a dozen broadheads at 50 before I figured it out. I'm thinking it must be some type of extremely hard angled steel in there.
