One day i got tired of checking if walmart had any "streamline" darts for my longshot, every time i go they say theres none in stock or they dont carry them any more, so i decided to make my own.
-Nerf Longshot CS-6
Step 1: Cutting the dart tip
Step 2: Getting rid of the dart tips edge
Then rip off the edge slowly, dont rip the Styrofoam(pic 2).
