Ahoy,
OK so ive been building a homemade its a shot gun design and its coming along great im almost done but there is one problem the darts are to tight. Im using 1/2 pvc with 5/8 FBR and the darts are really tight you end up squishing the foam just getting them in the shell. I didnt really think about this being a problem because the FAR uses the same stuff(What do you people do who have FARs?). So is there away to fix this or is it just that my pvc is a little smaller than most?
Ill post pics of the gun once its done should be about 2 weeks.

O and im just curios why none of you have built nerf mortors/rocket launchers somthing that would launch a lot of nerf darts at once? Ive been building spud guns for a while and it would be really easy to make one.
