.308 ultra-high speed photography

Even the thin lightbulb tilts the bullet!
The chalk makes it do a 90 degree turn (you are looking at its rear).
 
The cleanup was not even bad: the apple for example was split in two parts. The tomato was inside out, but still mainly in one piece. The chalk was spectacular: the entire range was in a colored mist that gently drifted away to the bullet stop on the ventilation.
 
Thanks for sharing that. I also read the blog, pretty cool. also nice to see an electrical engineering (used an arduino huh?) type with a fettish for bullet speed and capturing a bullet in flight. Really great stuff!

everything makes bullets yaw. In fact they come out of the muzzle with a bit of yaw, until they "get happy." It usually take 50m or so for the bullet to stabilize fully.

M80 has been measures with up to 15deg yaw at the muzzle, and M855 has been measured with, IIRC, about 12deg yaw. It's believed that the yaw variation is responsible for variable bullet performance at short ranges.

Hatcher noted that .30-06 ball would penetrate more oak at 50yards than at the muzzle, for instance.
 
Hmmm...

Some sort of open vessel with some paint, like a cup or a rattle can..
The end of a wood dowel rod
Ice, H20 or Co2
A stack of Justin Beiber CDs.
just a few ideas..

Notice how the bullet has already passed through the target and most of the damage is being caused by expanding material.

It would be interesting to see if a hunting bullet would start to open up on an apple or tomato. Something tells me it would because of the high water content. The faster you hit water the harder it gets.
 
Bullet Picture

I would like to dee a picture of a bullet pasing through 1/2" steel plate at 100yrds. I've seen what the plate looks like but not the bullet (a lead nosed hunting bullet) the plate curls out on the front side. That should make an awsome shot. Al
 
Should be doable with supersonic bullets: just tape the mic to the target and impact will trigger the flash. Nice idea for next time.
