It seems like that grain can be made with custom tools and a drill press. No?
Cool thread! I have some old SRS 38 and 54 motors and I think I have reloads for them still. I was saving at least one of each for exactly this use, EX Hybrid. I wish I could just buy them, they weren't very expensive. I even have the GSE, though some of it needs repairs. Guess I need to renew my Trippoli membership.
Dragon64: I'm very interested in hearing about how your 3D-printed grains do!
