Most .40" bullets are intended for .40 S&W velocities, so if driven at 10mm velocities, they'll be effective at long range, where .40 will have dropped out of the velocity window for maximum effectiveness.
I don't know that there are many .40" bullets on the market intended for 10mm velocities, other than the 135 grain from Nosler?
