He was not demonstrating energy (KE= MV^2) , he was demonstrating momentum (Momemtum=MV) which is also a measure of bullet performance but is also a demonstration of it's ability to "move" things.grobin said:What he was demonstrating is muzzle energy. It increases as the muzzle velocity squared. The formulia can be found here in too much detail at

Note that the 22 and 380 weren't too different from each other. Also note that the 22 is responsible for more deaths than any other caliber
Irreguardless of the bullet weight a heaver bullet does not hit harder than a lighter faster one-it may well do more damage.
Weatherby was fixated on "hydrostatic shock", the ability of a bullet to disrupt tissue via shock waves through the flesh. It is related to velocity more than anything else, not just kinetic energy.micro said:Research the history of weatherby rifles design. Mr. Weatherby and all his engineers believed in velocity over everything since way back in the 50's. Check out the muzzle velocity of the weatherby 300 mag compared to all the other 300 mags, win, rem, etc.
Yep. The weatherby 300 mag was my deer hunting rifle. Never had to track a wounded deer thru the mountains, hehe.22/45 Fan said:Weatherby was fixated on "hydrostatic shock", the ability of a bullet to disrupt tissue via shock waves through the flesh.

If the bullet doesn't penetrate the target, as it does not with a steel plate, then momentum is the factor that causes the plate to move.
I don't know how to break this to you but Super Vel is back in business and touting the same fly-weight/super high velocity ammo.DGW1949 said:If it did, the 'Super Vel' company would still be in business, and we'd still be seeing the 'fly-weight/super high velocity' type of handgun ammo which they pioneered being touted as the 'do all-end all' of combat ammo.

However, you make a valid point that sheer velocity is not the only measure of ammo performance and, as I tried to describe above, there are situations where momentum is more a more useful measure than kinetic energy.
That's the weak assumption in this argument. A light high velocity bullet is much more likely to fragment against a hard target and dissipate it's energy and momentum in directions that do not transfer momentum in a useful direction.427mach1 said:You can have a 500 grain bullet moving 1000 fps or a 100 grain bullet moving 5000 fps and they will both deliver the same amount of momentum to the target, assuming an inelastic collision. Trust me, I'm an engineer and I stayed in a Holiday Express last night......

Even if it penetrates the target and remains completely within it, much of the energy and momentum are dissipated sideways and not as a unidirectional "push". That's why "knockdown power" of even heavy bullets is a myth.
I'm also an engineer and have stayed in Holiday Inn Express in the past, but not last night.
