i need to do a ext trigger for a scope capture. the only catch is, i need to trigger on a bullet just as the nose of the bullet meets the start of muzzle exit. i was thinking of using optic path to trigger (like the eyes on a garage door). as reference, the speed of the bullet can be in the range of 600-4k ft/s
any ideas for me to look at?
