But since it is "such an easy-to-quantify commodity", smokinrope should let us know how much velocity is needed for a bullet to be effective. He won't provide it because he cannot.
LOL, I said KE is easy to quantify. As far as the velocity needed for a bullet to be effective, it depends on the bullet. I thought that much was obvious, but I suppose things aren't obvious when you have your head up your ass.
Velocity is easy to quantify - even easier than KE.
But you say "... it depends on the bullet." In other words, velocity alone tells you nothing, as I've stated from the start.
If that is not correct, just tell us how much velocity is needed for a bullet to be effective?
Give us a table...
