Made a couple two summers ago with/for my two kids. Double sleeved one of them just to see what it would be like. I was pretty impressed at how it could penetrate a target at 15 yards with a field tip.
I've got no doubt that it could take a deer with a sharp broadhead, probably a 2 blade cut on contact.
We used them for some bow fishing, and while my little dudes never hit their mark on a fish, the target practiced into some logs just under the surface of the water and it could get into those a few inches even with single pvc.
