Hybrid mechanical Bigbore Bullet

Okay so here is the idea,

I've shot crossbows with mechanical broadheads some are actually less than .45 diameter when closed. 

So what if a bullet was made that would deploy blades on contact creating a larger wound channel.

Now before I get a bunch of naysayers keep in mind there are now actual bullet cameras at a ripe price of something like $10 per bullet. Check out Hornady bullet cam..... 

If a bullet camera can be made a hybrid mechanical broadhead bullet could be. 

Expensive yes but when your big game hunting how much is it worth to get maximum lethality?

What is floating in the back of my mind is a lead sleeved system with a deployment trigger in the tip, or a counter weight hammer in the back so when the bullet hits the target the weight slamming forward opens the blades .

What do you think 
 
LOL, talk about sike! I wondered how they could record inside a spinning bullet 



DARPA actually funded a project that puts a camera into a 50cal bullet and it snaps a shot at the same point of each revolution so the picture stays 'stable'. It would be shot over the enemy positions for a 'snapshot' of the enemy's position. Remember video is usually 30 frames per second, and slomo is 120 or 240 Frames Per Second... just calculate the FPS of a .50 by the RPM of the twist rate. The picture stream is wirelessly sent back and has a 6 mile range so it works well on the close battlefield.

It was even tested using sniper rifles and shot into buildings to capture enemy positions inside but the signal transmission rate is too slow for that... the camera did 'see' in the room but the bullet impacted and destroyed before it could send back to the receiver.



UPDATE ON A HYBRID BULLET

I checked with a friend who is a precision micromachinest at his job and he told me "Sure, he could make a 3 bladed bullet of .357 no problem but it would be about $85 each. Said he could have 3 horn/nubs sticking out of the nose and when they impacted the sharpened blades would pivit out. It would be solid aluminium or copper as he said could not machine the lead. The blades would have to be stamped out or something.

Just sounds to expensive and delicate and I suspect the accuracy would be problematic due to balance issues around the center of rotation.
