I've seen that before..

I LOVE things like this.

Extremely complex and powerful.... Yet simple and, dare I say, "beautiful", too?

I was watching this behind the pharmacy counter at work. After about 30 seconds I realized the soundtrack probably made it sound like I was watching another form of entertainment.

Glad there were no customers at the time.

Serpicostraight, thanks for the posting. Very entertaining!

Some years back I saw one of these films done by Winchester. It was unique in that the high speed camera was mounted perpendicular to the bore axis but focused on a mirror at a 45 degree angle to the bore. The effect was such that you saw the bullet leaving the muzzle and heading straight for you until it impacted the mirror. They used various weapons and calibers as well as altering the distance from muzzle to mirror.

The long distance shots (approx 100 yds) were most interesting as, sometimes, you could track the bullet right from the muzzle to impact; others you lost sight of it against the background of muzzle blast and the round simply "arrived" quite by surprise. The trajectories were very clear in this film and, with some of the handgun rounds at this distance, rather exaggerated. In fact, comically so. More like "lobbed from a catapult" than "fired from a gun". Imagine a throw from deep right field to home plate and you have a pretty accurate mental picture of the arc.

5:05-5:13.... What's going on there, it looks like an entire unfired cartridge.... ?

Awesome, could do without the Euro-trash techno music though.

Physics question; from the 6:41 mark to around 6:50, the bullet smashing into armor plate appears to eject material back in the direction of the shot. This does not occur with the longer rifle bullets. Why?

I think it's cool that you can actually see a little bit of metallurgy in some of these shots.

In some of the shots against the steel, especially where the edge of the plate is in view, you can see what looks to be some "crystalline dust" kind of shatter and flake off - much like glitter. That's because as the metal hardens, it cools into a crystalline / granular structure. Yes, steel has a grain! And the shock of impact on the edge of the steel plates is actually loosening and sloughing off some of these grains AND breaking them apart into dust. (Can anyone tell I'm not a metallurgist by any stretch of the imagination?)

Also VERY interesting to see the differences in the AP ammo vs others as far as the penetration of the steel. Some of the bullets passed through almost without stopping / deforming while others punched through, but separated along the way.

Didn't someone already post this?

Still fun to watch again!
