I tried to get a photo of a 9mm bullet after it passed through an apple but my set up is not fast enough. I used a Miops Trigger set to the sound mode which would set off the flash set at 128 power.

I could get decent photos of the muzzle flash and the apple exploding but nothing of the bullet. The speed of the flash is based on the shortest flash duration. The flash I used w as a Nikon SB800 which gives a flash duration of 1/41,000
of a second. Further research indicated it would take a flash duration of 1 millionth of a second to totally stop a bullet.
How can this be done economically?

Dunno about a bullet but when I served in the US Field Artillery, I could stop 8mm howitzer rounds with (iirc) 1/500. Of course I needed no flash as this was outdoors during daylight hours. That was in the '50s though so maybe it was 1/1000, I can't remember for sure. I was shooting a Contax 35mm that I got through the PX in Korea. I started with a Voightlander, move up to the Contax. Sold it to a Dr. later when I got back to the states and returned to college at Ohio State, I was on the GI Bill and needed the cash. God, that was a long time ago, mid '50s iirc! :-) Harry PS I was in the Army '52-'54, in Korea '53. Damned NKs and Chinese were trying to kill me but we were beyond the range of their mortars while they weren't beyond the range of an 8mm howitzer which iirc was over 30,000 yards so I turned the tables on 'em!.

Usually this is done with expensive lighting.
PS, a 45 ACP is about 830 fps with a 230 gr bullet.
I can easily watch the bullet to the target when fired.
Try that.

Well you already have the photo of the apple exploding. Now just make a static photo of the bullet itself and paste it in! All done for pennies.

Lots of info, as to affordable, probably not!


Therein lies the answer. To stop a bullet I'm mid-air you need a flash duration of one-millionth of a second. I don't know if that kind of stroboscopic equipment is available outside of a laboratory setting. Perhaps somee ballistic analysis research is in order. I have seen images of bullets in flight showing their striations. I believe this kind of imagery is used in forensics investigations for specific firearms identification.

The next time you have company, serve the drinks in glasses like this. It should result in some interesting conversation.

My brother and I used to shoot across canyons to 200 yards at small rocks, 8-10 inches, on the other side with Smith and Wesson Chiefs Special revolvers in 2 and 3 inch barrel models, 38 Special caliber. By knowing where to aim the rocks were not that tough to hit. Dennis


Some people have a knack for this sort of thing. I do not, not at 200 yards.

It isn't a knack, it's a technique that requires a place to practice and learn the hold over. In a Canyon, you can practice safely, see the dust of misses and learn to correct. I won't claim Snubbies at that range, but been there, done that with a variety of others.

ROFLMFAO Dunno why I said 8mm, brain lurch I guess. I meant 240mm, biggest howitzer the army had at that time. We sat way behind the front, could shoot miles into NK. We didn't have quite the range of the 155 gun but we were more accurate. They'd wake me up every night that I wasn't on duty, firing H and I (harrassing and interdiction) after midnight. Loud mothers and the BOQ was on a hill right behind the battery. You couldn't sleep through those boys going off. We'd usually get up and have a Tuborg or two. Or mayne a Kiren. (to help us sleep, of course) Harry PS We got some horrible CA beer in the PX so I'd go down to Seoul to an import company and buy *real* beer! I'd bring back a 3/4 ton truck full of beer. Can't remember the name of tha CA beer but it was in a gray can with blue stripes. I'm a long time beer drinker (my fav is Labatts) and that CA beer turned my stomach. Everybody hated it. I was probably the most popular PX Officer in Korea! Harry

I was killer at 100 yards, still prety good at 200 but at 300 I was lucky to hit the d^mn target. Good thing that I didn't have a sniper MOS!

I love your post but surely you don’t mean an 8mm howitzer round. 8mm or .323 was the diameter of the projectile from a Model 98 Mauser in 7.92 or commonly 8mm Mauser cartridges. Of course there are many other 8mm cartridges. I chose just the one.

Exactly right my friend.

Some will call it luck but the more I practice the luckier I get.

I was thinking the same thing - fake it until you make it.
