high capacity metal frame 45
Wow, sounds like I’ve been missing some good entertainment …
I know Wing you don’t take kindly to science but let me add my 2 cents here …
My calculations yield the following:
KE of a 230 gr 45 cal projectile leaving the barrel at 830 ft/sec equates to about 353 lb-ft at the muzzle.
A 700 gr 50 cal at 2700 ft/sec gives a KE ~ = 11.32 e3 lb-ft of energy at the muzzle.
On the surface one would think that there is more than enough energy to lift a human off the ground --- the issue is getting a significant amount of the energy from the bullet into the human in the right direction. In order for the bullet to lift the human off the ground enough energy must be transmitted in the opposite direction of the force vector holding the human to the ground, for 250lb man this is 250lbs.
So you have two problems:
1)Getting the energy into the human, (bullet can’t exit). (Assume that all energy is available at impact).
2)Applying the energy in the direction to counter gravity.
It is my guess that more than likely the 50 cal traveling at 2700 ft/sec is going to pass right through any material of the density and thickness of a typical human. But to be honest I have no idea what the transfer characteristics are for either round. Hitting something dense like a bone helps keep the energy in the body, but again I doubt that the bone does little as a directional element.
The real problem is that the applied force is generally normal to the force vector generated by the acceleration vector of gravity. If anything happens I would expect the human to rotate about a fixed point. Think force on a lever arm.
Here’s an experiment, get 250 lbs of ballistic gel, (or maybe a calf or pig carcass would be easier), and suspend it.
Shoot directly normal as if shooting at a standing human. Have your video cam going and note the direction of movement.
Does it jump up or does it rotate?

Hey WW,
Is the video being discussed in this link the same as the one you're talking about?
Read through all the discussion and you will see the varmit video ... is it the same as your's?

Looks like the link to the rock chucks were deleted from the previous link.
After reading the discussion on the previous link try this new one and click on the rock chuch video.
