How Different Arrow Tips Affect Accuracy and Penetration?

My project is about a question I asked is does metal vs obsidian arrow tips differ in penetration and accuracy. Another thing I wanted to know is how the wound channels impact penetration as for broadheads a good chunk of their purpose is to penetrate into an animal or in wars an enemy then create a wound channel to make the wound bleed more thus killing quicker. I choose this project because I was interested in learning more about the differences between the two and some things i really wanted to know and sorta knew or thought i knew and put them to the test. My results were field tips being their bullet like design penetrated right through our target, a pumpkin, while the metal broad penetrated 9 inches and the obsidian's arrow head penetrated 9 to 9.75 inches. This project is important because for bowhunters whom use recurve maybe want to use this as an extra challenge or also because it proves that sometimes old technology is as good as the new.
Very cool project! I learned a lot about different arrow types and their uses. I also appreciated all the research that went into your project!
Hand-building obsidian arrows with pine glue and rawhide to test against modern carbon tips is an original idea!
You were honest about missed shots and broken shafts. Real scientists report what actually happened, not just what they hoped for.
Your research paper connects arrow design to human survival, medieval warfare, and modern hunting. That shows wide thinking about a topic you care about.
Your analysis calls out what surprised you, like the broadhead result, and that is good science talk.
very descriptive and checks every box amazing experiment
