High speed ballistic pictures

[Fingunner]

Here are couple early stage ballistic pictures of .22LR and 9mm.

.22LR Benelli MP90:

9mm STI Edge:

These are also posted in two US forums but thought you'd be interested seeing them here as well.
Surprisingly that 9mm shot was very messy with that shotgun like particle cloud flying.

cool shots!

that 9mm doesn't look like its gonna be accurate from that second shot. it looks like its low already and on a downward trajectory

Oddly enough that's not likely to impact accuracy all that much. Most bullets tilt and yaw somewhat upon leaving the muzzle, then spin stabilize after a few yards.

The amount of yaw is surprising, it is an issue in close-quarters wounding.
You can see why muzzle crown is important from the first picture.

I am surprised by the amount on muzzle fire on the 22lr! I thought it would be less!

Having spent sweeping time at an indoor range, I can attest that 9 mms put an enormous amount of unburied powder particles on the floor but 22s mostly burn completely their load.

:O Do I buy more guns, or a high speed camera? This is awesome

 

[JR Hartman]

cool, thanx for the info! its kinda like an arrow that way I guess. they flop about quite a bit in the first little bit, then stabilize too

Yep, they wobble quite a bit when leaving barrel. Not all of them though.

It can be done with a regular SLR camera, no need for anything fancy. Actually, the more manual it is, the better. A basic film SLR camera is ideal. You also use a regular flash unit to freeze the bullet, as close up a flash can be as short as 1/20,000 of a second in duration. A microphone is used to trigger the flash, so it is the gun going off that makes the picture. Normally this is done in total darkness with the shutter on the camera open, so the flash provides the only exposure. The microphone can be moved closer or further away from the gun to determine when the flash will go off and how far out of the muzzle the bullet will be when the flash goes off. I'm not sure how many ranges would like you firing guns in total darkness though.

This technique has been around since the 1930's, pioneered by Harold Edgerton, the inventor of the flash. He loved shooting things while taking pictures of them, see the famous apple picture:

And the playing cards:

 

[Fingunner]

Small sample on bullet wobble with silencer (in false color).

I try to put plain barrel vs. silencer comparison online during weekend.

 

[Fingunner]

Small comparison of naked barrel and silencer online. Go and check.

See how bullets are tilted. I took today couple tests with .308 and can say that they were line straight.

Two samples:

 

[Fingunner]

How about .308 for a change? This is Sako .308 with 147grs FMJ with plenty of moose kills.

Picture is a bit big and odd shaped for forum but you can find big one here.

Small dose of eye candy for you:

Three image set on site.

 

[Slavex]

nice pics dude! you should post these over at pistol-forum.com just make sure to include as many pics as you can and your descriptions in your posts, not just links back to your site. Otherwise the mods will think you are just spamming for hits. (guys do it with their blogs and youtube pages all the time)
