Wondering why the .40 velocity is so low? I always thought .40 blasted out close to 1300.

That's 10mm velocity
That is false. The study was probably using standard 40 s&w rounds. Hot 40 s&w rounds will reach 1300 velocity.

It seems that test is very old. Many different defense rounds in each caliber to choose from then and more now.
A 45acp in the 230gr flavor can be had closer to 950fps, 185gr closer to 1050-1100.
Meh, all the calibers tested will do just fine.
