Home Forums Hunting & Shooting Handguns The 40 SUPER!

I don't have a problem with your nickname for the 10mm, but I don't agree with your comparisons of it to the 40 S&W.
First of all, the 40 S&W has a SAAMI pressure standard of 35,000 psi. The 10mm, in a slightly longer, .85 vs. .992 inch case, has a SAAMI standard of 37,500 psi. That isn't a big difference. The .38 Special vs. the .357 Magnum have a much wider pressure difference. The .38 Special is rated at either 17,000 psi, or about 21,000 psi for the +P ammo. The .357 Magnum, however, is rated at 35,000 psi.
I'd also point out that the "original" 10mm ballistics cannot be duplicated unless one exceeds the 37,500 psi limit set by the SAAMI. E
