Back to playing with a trigger. Now on Mk3, and at least the pellet is now in frame

even if I have lost alignment of the card. Mks 1 & 2 suffered from bounce and so strobed the flash

.
Attatched 2 shots of the same card. HS Flash 6 really shows what happens to the trajectory of a flat head pellet after cutting 3/4 of its way through the card. The card distortion is the result of the pellet impact and it had nearly returned to flat by the time exposure was over.
Once again, flash used is a Vivitar 283 at a flash duration of 1/30,000 sec.
