Great video of bullet yaw and precession

As the title says, here is a great video of a bullet yawing and precessing.

Discussions rarely have good visuals for the phenomena.
Bookmark this one for when it's needed.

The good stuff starts at about 6:06.

It may be a very big bullet, but the physics are the same.
Note the shockwave that's visible, even when they weren't set up with the intent of capturing it.

That was beautiful, mesmerizing. I could watch stuff like that all day. What an experience it must be in person.

Amazing.

I would have lost a lot of money betting against something like that happening.

Wow. I try to keep up with them, but somehow I missed that one.

I knew that bullets yawed and precessed, but I didn't think it would be that much.

That was great. If seeing an artillery round deflect after hitting a watermelon doesn't disprove the theory that large caliber rifles don't get deflected by brush nothing will.

Fun stuff!

I think I once heard or read that a 155mm projectile weighs right around 150 pounds. Something like that can be deflected by a watermelon? Amazing.

I thought it odd how twice in the first firing the round starts to yaw and corrects itself. That shock wave, I've never seen it so clearly visible. Cool stuff!

rickyrick · May 25, 2020, 02:08 PM

Yeah the watermelon deflection was unexpected.

TXAZ · May 25, 2020, 03:03 PM

The definition of cool!

Very instructive, and not something that most people would be willing to accept unless they saw it happening.

That's what the rifling does for you. It probably keeps wobbling for quite a long distance downrange, but the spin keeps it stable. Otherwise it would just tumble.
