Federal Vital-Shok 180 grain Cast Core Velocity

[Southern Shooter]

.357 Magnum Federal Vital-Shok 180 grain Cast Core Velocity

I am trying to find out if anyone has obtained velocity numbers on this ammunition from various revolver barrel lengths.

Specifically:
2.75"
4"
6"

Also, I would like to know which gun brands/models the rounds were fired from.

Thanks
