2.5" heavy round

I just discovered the perfect ammo for a 2.5" sch 40 barrel: Redd's Wicked Apple cans. The fit is tight enough to not need wadding but not so tight they would get stuck without grease. My plan was to make something similar to those Nerf footballs with fins. The can will be filled with concrete or plaster or something heavy like that. I'm making a tail with some old CPVC pipe and cardboard fins that I'll stick into the wet concrete/plaster/etc. I'm not sure what to do about a nose cone if I even need one at all.
A few years ago I tried something similar with 90 calorie soda cans just filled with concrete (without fins), but I never got to use them since I went off to college before I finished the cannon. Now that I'm allowed to use the machine shop at school I should be able to make a good piston valve from a solid PVC slug.
