As a strictly mathematical calculation, since velocity squared times mass equals energy, the .357 Sig should have more "energy" to dump into a target because it's got more velocity and velocity is worth more than weight when it comes to energy.
But the .40 makes a bigger hole, will open-up or mushroom way bigger than the .357 will, and should penetrate deeper than an identical bullet in .357 caliber.
357
The .357 has a longer case and a heavier bullet; it is identical to a .38 in diameter but far more powerful. This is why a .38 will fire in a .357 but not the other way around.
Which .50 cal, and do you mean .357 Magnum? If you're comparing the .50 AE to the .357 Magnum, the .50 AE is more powerful, by far.
No
No.
32. Cal
Yes, the .500 S&W Magnum is a significantly more powerful cartridge than the .50 Action Express used in .50 cal. models of the Desert Eagle.
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
No
the 40 cal is a little bigger then the 357
a 357 cal. revolver cartridge WILL fit a colt 357 python. Also, a 38 special will fit a 357 cal. python. The 357 sig cartridge will NOT fit a 357 colt python................ The 357 sig cartridge ONLY fits the sig model pistol For clarity.....the sig 357 is a pistol. But, the 357 python is a revolver................
400
