Cement molds and making cement slugs
For my new air cannon, which I will post this weekend when I finish it, is going to shoot these cement slugs I made. Pretty straight forward, cut pvc lengths diameter of your barrel and fill with quikrete cement.
What would be the best way to make the slugs have a semi-pointed tip like a nosecone of some sort after they dry? this would make them fly faster, farther, and straighter it seems like.

what about forming a cone out of aluminum foil in a hole in the ground, stick the pvc over it, and fill?
What about the wear you'll be causing on your barrel? Maybe you should make sort of a liner in the PVC out of plastic wrap before filling with concrete.

I'm weird, I know it, you don't need to tell me.

Use a wooden dow or rebar and a funnel.
Stick the wooden dow or rebar through the smaller hole in the funnel and then pour the concrete mix around that. Once it's cured you can cut or grind the dow/rebar off to a point after you push the slug out of the funnel.
A concrete slug travelling down your barrel at several hundred (hopefully) FPS will grind that baby down in a heartbeat.. So it better be smooth as a babies crack.

Sounds like a GREAT idea to me.
By the way i'm being sarcastic.
Surely you can think of a better material to use than bloody concrete

cone shaped dixie cups with a washer in the base, then fasten it to you mold and fill with something else other than quikrete. it is too abrasive.

Having a pointed nosecone won't have them flying any straighter, to achieve this you need a hollow tail - here's a suggestion on how to achieve it.

To make a pointed tip all you have to do is add another cup to the top of the pipe with a hole on top to pour the concrete through, why waste precious epoxy
