Actually I did message you before trying to fix it on my own, asking you about the magnet screw.
June 30th: "What what is the size of screw used for the brass magnet screw? I'm trying to reattach the head to the extension pin, and if I can find one just a little longer, I can use that to pressure screw or to the pin through the bullet, the current one is just a little short."
However, trying to use a longer screw as a retention screw against the pin inside the bullet didnt work when it got tight enough to loosen the nut that was glued into it. Either way, I knew I was going to have a bit of work to do, I was just surprised that most of the glue failed as I was fixing other things. I'm capable of fixing it, so I'm not too concerned about it.
The halo paint was fine until i scratched a small edge of it off, then it all started peeling. I'll just end up repainting it.
