Kurt I am not saying there is anything wrong with them and I am sure they will work and if they fly great that is fine but, I just think there is probably a better choice for a small diameter head, even more so if you are going to use them in an expandable mode. I would rather shoot those old rocket expandables to get some cutting diameter if i was going to use an expandable. Just my opinon, and don't worry about that because Hey, I am just an elk expert from Wisconsin
