Videos of pellets in flight ... first effort.

BSA Hornet .22, 14.3 gr JSB Express; rifle detuned to 775 fps, 19 fpe.

Range = 25 metres/ 28 yards.

Verrry shaky rest on a cupboard, attempting to use a Casio snapshot camera with high speed video system attached to the scpe with a Seben bracket system after the fashion of Ted in Madison USA. The pics are taken through the scope so the sighting is done on the camera view screen.

You might have to "Replay" each a few times especially the first which I cut too much off the front end of the video when editing it.
Best viewed full screen by clicking the bottom right corner of the video. You can get back to the script my using the Esc key.

The pellets" shine because they passed through a range where the sun was shining up their skirts.

# 1. 240 frames/ sec; scope at 12 X; camera at 10 X.

# 2. 420 frames/ sec; scope at 12 X; camera at 10 X.

# 3. 420 frames/ sec; scope at 8 X; camera at 10 X.

Nice to see the three shots find there way into a one hole clover from such a shaky unstable rifle position. But then the BSA Hornet actually shoots itself, it doesn't need me :-).

This is the "group" (if it can be called that for three shots) formed:

The learning curve for this old fella is rather steep. Not sure now how I got it all from camera to computer to Photobucket to here. Plenty to learn about working the Casio EX-FH 100 camera too. Really need to move the whole shebang well forward on the rifle to enable field shooting. That means a rail of some kind for the scope to be moved forward.

Any help in all this is welcome..

........... Kind regards, Yrrah.

That's some pretty kool video work.

I doubt you would have seen the pellet fly that clearly if the sunlight did not flare out the skirts.

I remember taking my Theoben to the 50m small bore range and at the end of the card taking a few shots when the tank was very low and actually seeing the pellet flight throught the scope.

Nice work

Nice work Harry, I've managed to bond a video cam onto the rear of a scope with the help of ebay. :D
Not got around to testing yet though. :oops:
Anyways, another interesting video link below I came across a while back.
