You don't have even the slightest clue what you are talking about. The sneering reference about anti-gunners is surprising and unnecessary.
Your math example presumes one bullet is "357" and the other "38." Then you determine a 357 is
over 9 times the caliber and therefor about 9 times the "power" because you divide one number into the other. Wrong.
A 357 bullet has a
diameter of .357 of an inch, not a "mass" of 357. A .38 has the
diameter of .38 of an inch, not a "mass" of 38. Virtually identical. That is how caliber is measured.
Since the bullets are virtually identical, except a .357 is a little longer, this is why a revolver chambered for .357 can fire .38 rounds also. Which I wrote about in my original post. Many people, like me, have a .357 revolver but target practice with that gun while using .38 ammo. Then "carry" the gun loaded with .357 rounds. Which are admittedly a more powerful round and which I never disputed.
James, you post some really good stuff here. But you whiffed on this one.
This is according to the Firearms Guide:
"the caliber of a bullet is the measurement of the diameter of the slug (or projectile) part of the bullet cartridge."
