I recently came to possess a large quantity of regular 550lb rated 4mm nylon paracord. Up until now, I have only ever used rubber and fabric elastic bands or kevlar for shock cords as I have only flown low and mid power. Providing I sufficiently protect the bottom end of the paracord from ejection heat, (baffles, nomex wraps, etc.) would this be suitable as a shock cord for mid power rockets? What about level 1 HP?
