Is there any photo/video of flying rifle bullet done with v2 camera?
Is similar photo or video of flying rifle bullet ever done with v2 camera?
Since two days I know that it is possible (with very very bright light, 10000lm) to shoot 1000fps videos with 19.5µs(!) shutter time. But because of v2 camera being rolling shutter camera and 640x480 mode 7 line_time_ns=19517ns=19.517µs most likely a v2 camera bullet image will never look that sharp as above (the phantom camera has 73 times the fps than the v2 camera 1007fps).
I do not own fire arms nor have used any in the last 35 years after general conscription, so it is the question how to try v2 camera bullet photo/video. Anyway from movie I knew the name Glock and looked up its muzzle velocity as 375m/s. That is 19 times the 20m/s I was able to deal with with v2 camera in this posting:

This is a frame from 1007fps video of closing mouse trap where the closing bar has 20m/s speed:
The frame horizontal 320 pixels correspond to 10cm, the vertical 75 pixels to more than 2cm.
With that view a 20m/s bullet would move 2cm every millisecond of a 1000fps video.
So the 10cm allow to capture movements of up to 100m/s(!).
Now doubling the current distance between camera and mouse trap (36cm) would allow for 200m/s.
After several shots and videos some bullets should show up by probability > 0.5 of this setup.
With 72cm distance vertical 75 pixels correspond to more than 4cm.
As example, a 9x19mm Parabellum firearm cartridge bullet has 9mm diameter. That would results in perhaps 15 pixels vertically when shot from left to right through camera view.
Now to the rolling shutter effect. The 15th row will be captured 14*19.5µs=275µs=0.275ms after the 1st row. In that time the bullet will have flown 375m/s*0.000275s=0.103m=10.3cm ... with 1cm bullet length only a very distorted bullet frame (11.3cm x 0.9cm instead 1cm x 0.9cm) could be captured with v2 camera ...
I once did a v1 camera 665fps video of a Nerf Toy gun, but the dart moves with only 18.6m/s:
