We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
This demonstration makes the entire Magic Bullet theory of the Warren Commission look stupidly and criminally wrong!
That theory: a single rifle bullet penetrated JFK's and John Connally's bodies, causing six separate wounds , crashing through both skin and bones and emerging with only a slight deformation at the base of the projectile, was the basis for the Commission to conclude LH Oswald was the lone gunman/assassin in Dealey Plaza.
BS! Skin is a hundred times toughr than a balloon and bone is rock-solid. Yet a .44 magnum fired form 6 fett could only penetrate 4 water-filled balloons and was severely deformed.
Well, the bullet Oswald fired was a fully-jacketed military cartridge not much more than half the diameter of a .44, so I would expect it to have much higher penetrating power with far less deformation, than did this .44 round, which appears to have been a hollow point round, given the exceptional expansion we see at the end.
Though the two exhibit fairly similar ft-lbs of energy, you really can't compare the two in terms of ballistic performance.
You are correct that Oswald's rifle bullet was about half the diameter and also roughly half the weight and that it carried a lot more energy than a .44 magnum. However, IIRC, Oswald's bullet was supposed to have hit bone, too which would definitely have deformed it. Also, IIRC, the "magic bullet" was supposed to be a pristine projectile found on a gurney in the hospital. There is no way a bullet would have gone through even one person and not show some deformation.
The Warren Commission was a joke - regardless of validity of the magic bullet theory. Ultimately a joke on us. Why is it that a Kennedy (or pretty much any demoncrat) or what happens to him can't be honestly investigated?
